RT Video of Teachers’ Demonstration in Washington against Betsy DeVos

October 17, 2017

Betsy DeVos is Trump’s education secretary. She’s a multimillionaire member of the family behind the Amway pyramid scheme, who has never attended a public, that is, state school in her life, and as a bright red corporate Republican, hates them with a passion. She, like her master, Trump, wants to privatise them, and turn them into charter schools. This means that they will be able to circumvent the state legislation regulating teaching standards, the pay and conditions of teaching staff, just like Academies in the UK. And in the case of America, they will also be outside the legislation outlawing the teaching of religion in schools.

Teachers in America, like those in Britain, are extremely worried and angry. This is a video by RT America of a demonstration by public school teachers outside the Hyatt Regency Bellevue Hotel in the state of Washington last Friday, 13th October 2017. The assembled educators have placards proclaiming ‘Stop Fascism’, protesting the privatisation of the American school system, and demanding an end to the road from school to prison. I don’t know the particular symbolism, but some of the female demonstrators lined up to wear 17th/18th century dress with red capes, holding placards, which read out ‘This nightmare will end’.

Mike and I both went to Anglican church school in Bristol, and I have absolutely nothing against the teaching of religion in schools nor the state supporting faith schools. I’m not a secularist. Religious education in British schools hasn’t prevented the increasing secularisation of society. Religion, and more recently the attempts of secular philosophy to grasp with the deep issues of humanity’s existence, morality and meaning, have been part of human culture and identity for centuries, if not millennia. It can also be argued that we need proper teaching about each others’ religious beliefs as society has become more plural and multicultural, so that children do not get distorted or bigoted pictures of our fellow citizens and their religious beliefs or secular philosophies.

But I’m also aware that American society and educational tradition is different, and that there are quite legitimate concerns that what these schools will push is not education, but indoctrination. Just as there are concerns over here about the extremist agenda pursued by some of the new faith schools established in the UK.

Mine and Mike’s mother was a junior school teacher for many years, and I did my first degree at an Anglican teacher training college, and so have some understanding from the inside of what teachers face. Contrary to what the Republicans and Conservatives would have us all believe, teachers as a rule don’t want to indoctrinate children with lesbian feminist cultural Marxist propaganda, although they do want to make sure that girls as well as boys reach their academic potential, and they do have a statutory duty tackle prejudice, including homophobia. But most of all, teachers want to stand in front of a White board and teach. And those I know, who’ve done it state that it’s immensely rewarding. They want to see their pupils do well, and become bright, inquiring members of society. They want to pass on the interest and passion they have for the subjects they teach, whether English, maths, science, history, whatever to the children in their care.

I’m perfectly aware that there are some terrible teachers. But the good far outnumber the bad. Teachers in this country have been appallingly treated by successive governments ever since Margaret Thatcher, and the attempts to privatise, or part-privatise schools through their transformation into academies and charter schools threaten educational standards, as well as the pay and conditions of the teaching staff themselves. This country has suffered from wave after wave of qualified teachers leaving the profession as conditions have become worse, demands increased, and in some cases even dangerous. There have been cases where teachers are assaulted. At the same time, like other public sectors workers, pay has been cut or frozen. They have not been given the support they need by the authorities, and in the case of the Republicans in America and Conservatives over here, they’ve actually been demonised and vilified. Over the decades newspapers like the Scum, the Heil and even the Torygraph have run article after article trying to scare the British public with stories about how left-wing teachers are indoctrinating Britain’s children. Under Cameron, we had Michael Gove whining about history wasn’t being taught properly. It should be more patriotic, with children taught the approved Tory version of the First World War, rather than Blackadder. As Mike pointed out in a series of articles he put up about it, this would be to distort history for the Tories’ own benefit. As well as mistaking a comedy, based on history, with history itself.

In the 1980s, my mother felt so strongly about the threat to British education that she and the other teachers in her union took industrial action. As did very many others. This was not done selfishly to maintain their own privileges at the expense of their children. It was also because they were very much concerned that unless strike action was taken, the Tories would continue to run down the British education system. As they have, and Blairite New Labour as well.

The transformation of America’s public schools into charter schools is undemocratic, and hasn’t just been done by the Republicans. Obama also pushed for it. And like Blair in England, schools were often taken out of the state sector and made charter schools against the wishes of the community, parents, teachers, community groups, pastors and clergy. The Black community in particular has been threatened by the fall in educational standards that they represent. A year or so ago the veteran civil rights organisation, the NAACP, came out against them. There are books over here about the failings of academy schools. One of the pamphlets I’ve written is against them. If you want a copy, just let me know in the comments and I’ll get back to you.

But DeVos and the corporatists want a privatised school system both as a source of profit and because they would transform the school system from proper education, to a system of creating a passive workforce, who have enough knowledge to work for their corporate masters, but not enough to question, think for themselves, or even to be able to participate fully in art and culture. Art and music along with other humanities are being dropped from the curriculum in Britain as schools concentrate on the STEM subjects. And this is harming our children’s education.

C.P. Snow talked of the ‘two cultures’. He felt that there was a real gap between the arts and the sciences, so that the two formed distinct, separate cultures with little contact between each other. I think his fears, however true they were when he was writing, are somewhat exaggerated now. Science and mathematics has inspired much art down the centuries, as you can see from the weird paradoxes of Max Escher or the new scientific experiments that were painted during the 18th century by Wright of Derby. And scientists and science educators like the late Carl Sagan and even Richard Dawkins have expressed an extensive knowledge and keen appreciation of art.

This is why teachers are protesting against academies and charter schools: they want to preserve proper educational standards. They want to make sure that the poorest children have the same opportunity to achieve as the wealthiest. They want education to receive its proper status as a public good, not the preserve of the affluent, or simply another revenue stream for a grotty multinational like Murdoch’s. And although in Britain religion is taught, or supposed to be taught, in schools, there are safeguards and legislation against indoctrination. And teachers wish to preserve those as well.

So stand with your community teachers and teaching unions, and don’t let the Republicans in America or the Tories in Britain turn your school into an academy.

BBC 2 Programme on ’21st Century Race for Space’ Next Tuesday

August 30, 2017

Here’s news of yet another BBC programme on space exploration and science. Next Tuesday, 5th September 2017, physicist, broadcaster and massive Carl Sagan fan Dr. Brian Cox will present a programme, The 21st Century Race for Space, on BBC 2 at 9.00 in the evening, on the private companies planning to take humanity into the High Frontier. Among the scientists and engineers he interviews in the programme are Richard Branson and the founder of Amazon, Jeff Bezos. The blurb for it in the Radio Times runs

As a new age of interplanetary exploration dawns, it is private companies and their maverick owners who are planning to finance space tourism, asteroid mining and even colonies on Mars. Professor Brian Cox investigates the technical challenges that could stop these billionaires achieving their dreams and also finds out how they hope to overcome the daunting obstacles to human space travel. Sir Richard Branson is among the stargazers explaining how they plan to fly through the heavens. (p. 76).

Another piece about the programme on the previous page, page 75, by David Butcher, also adds the following

When the likes of Richard Branson or Amazon founder Jeff Bezos enthuse about space travel it’s easy to be skeptical. But when Brian Cox meets both billionaires for this engaging look at “the prospect of us becoming a space-faring civilization” he comes away convinced by their vision, their desire to push boundaries and to make sci-fi stuff happen.

And for us, it’s hard to see the various hangars and labs and prototypes and launches and not get the feeling that space tourism, mining on asteroids and trips to Mars really aren’t that far off.

Cox is a good guide, leaning towards the deeper questions implicit in the subject. Ultimate, one designer argues, space travel is about “building life insurance for the species.” Though you hope we won’t need it.

That snippet also has a photo of Cox and with the space scientist, Brian Lillo, in space suits outside a Mars Society Research Station in Utah, ‘exploring the Red Planet’.

I went to a symposium 17 years ago on space tourism at the British Interplanetary Society’s headquarters in London. There are no end of really great ideas, and very motivate, intelligent people out there planning and discussing ways to take people up into the Deep Black for their holidays. One of the scientists, reviewing previous spacecraft designs going back to the early days of spaceflight, showed how sophisticated some of these were. He made the case that we’re actually decades behind schedule in our ability to explore and commercially exploit space and its resources.

Radio 3 Programme Tonight on the Voyager Interstellar Record

August 29, 2017

Tonight, 29th August 2017, at 11.00 O’clock Radio 3’s contemporary music show, Late Junction, has an edition marking the 40th anniversary of the golden record, which has taken sounds from Earth into interstellar space aboard the Voyager space probe. The blurb for it in the Radio Times reads

Late Junction marks the 40th anniversary of the Voyager Golden Record, a sonic time capsule sent into space by NASA to transmit earthly music , sounds and languages to extraterrestrials. A committee chaired by Carl Sagan selected the contents of this ‘message in a bottle cast into the cosmic ocean’. Nick Luscombe wonders what sounds we would send out into the universe were we to do it again, as well as playing the best bits from the original Golden Record, including a Navajo field recording, mariachi from Lorenzo Barcelata and court gamelan music from Robert Brown.

Stephen Hawking’s Defends NHS as Hunt Lies about its Privatisation

August 22, 2017

I know the Tories will immediately complain about the title of this article, but that’s exactly what’s going on. The Tories have been privatizing the NHS piecemeal since the 1980s, when Maggie Thatcher wanted to sell it off completely and replace it with an American-style insurance based system. Thatcher was prevented from doing so through a massive cabinet revolt, plus the fact that her private secretary, Patrick Jenkin, found out how appalling the American system was after he actually did some research and went there.

But the privatization is still going on. There was a mass exodus of dentists in the late ’80s-early ’90s, after Maggie – or was it Major?-refused to give them any more money. Then came Peter Lilley and his Private Finance Initiative, in which hospitals were to be built and run for the NHS by private contractors. Then New Labour expanded this massively, breaking up the NHS internal structure to model it after the American private healthcare system, Kaiser Permanente. Blair was approached by a whole slew of American private healthcare companies. His idea was that hospitals and clinics should be taken over by private healthcare companies, like Circle Health, Virgin Healthcare and so on. The community care groups of doctors, which were supposed to commission healthcare for their patients, where to obtain it from both private healthcare providers as well as the NHS. And they were also given the powers to raise money from private enterprise.

And before anyone objects that Blair was a Socialist, no, he wasn’t. He had Clause 4 removed from the party’s constitution. He was also profoundly hostile to the trade unions, who have formed part of the very core of the Labour party since it was founded in the very early 20th century.

Blair was a true, blue Thatcherite. The first thing he did when he got into power was invite Thatcher round. And she responded warmly, declaring New Labour her greatest success. Remember, this is the woman, who proudly shouted about how she was going to destroy socialism.

And the Tories have carried on her project of gradually destroying the NHS, bit by bit, while loudly proclaiming how much they’re in favour of it.

The present Health Secretary, Jeremy Hunt, is a prime example of this. He even wrote a book in which he declared how much better everything would be if we had a private healthcare system, like America.

Yeah, like America, where the poorer parts of the country don’t have any doctors at all, because it isn’t profitable. Where once a month, in Virginia, people sleep in cars overnight in order to join the queue for the doctor’s or dentists’ surgery offering free dental care that Saturday.

Where something like 20 million Americans can’t afford their medical coverage, and 30,000 people die every year because of this.

And where the Republicans and corporate Democrats have been lying and smearing Bernie Sanders, because he dared to run on a platform of ‘Medicare for all’. You know, giving Americans state-funded healthcare, like in the other parts of the world.

This is what the Tories are doing to Britain. And last week, as Mike reported on his blog, Stephen Hawking, the great cosmologist, called them out on it. He also accused Hunt of cherry-picking the data about the supposed deaths caused by NHS staff not working Saturdays.

Hunt got terribly upset about this, and declared that Hawking didn’t understand statistics.

This is a joke from a professional moron. Statistics are a vital part of science and medicine. Much of modern science, including astronomy and cosmology, is going through the data, trying to find something that is statistically significant. It can be time-consuming, tedious work, requiring sophisticated techniques to sort out what’s importance from apparently random results.

Hawking’s a physicist, who has been working with some extremely advanced maths as part of his investigation into the origins of the cosmos and the nature of Black Holes for his entire career. I don’t believe in his ‘No Boundaries Solution’ to the problem of the origin of the universe, but it’s abundantly clear that he understands stats. And as a man stricken with Motor Neurone Disease, a terrible illness, which has left him confined to a wheelchair, unable to speak and scarcely a muscle, Prof. Hawking clearly has first-hand experience of NHS care.

In short, don’t believe Hunt. Believe Hawking.

And yesterday one of the doctors weighed in, to request that a televised debate should be held between the two. See that story on Mike’s blog.

I’ve got no doubt that this will never happen. The schedules are full already, and the last thing the Tories will want is putting their man in a position where he’ll lose against a vastly more popular, far more respected and definitely more intelligent opponent.

Although they’re both authors. Hawking’s most famous work was A Brief History of Time, published back in the 1980s. It was a national bestseller, following very much in the footsteps of Carl Sagan’s epic Cosmos, another pop-sci blockbuster from a great science communicator, as well as a concerned scientist who attacked militarism, imperialism and man-made global warming.

As for Hunt, very few have read his book, which is why he can still repeat the lie that the Tories aren’t privatizing the NHS with a straight face, despite having advocated himself.

Such a debate would be so unequal in Hawking’s failure that I’ve no doubt that the Tories in charge of BBC News, the same people, who gave Corbyn such overtly biased coverage during the general election, are blanching at the very thought of it. Such a debate will never happen, just as the BBC will never own up, and confess that they, and particularly Laura Kuenssberg, are massively biased and everyone, who has complained about this painfully obvious fact is absolutely right.

The Young Turks on the Republicans’ Hatred of College Education

August 20, 2017

‘Do I detect an air of anti-intellectualism in this country? Came in about four years ago.’

-Bill Hicks, American comic, speaking four years after the election of Ronald Reagan.

Earlier today I posted a piece commenting on clip from Sam Seder’s Majority Report, about Rush Limbaugh’s mindlessly stupid ridiculing of NASA’s announcement that they may have discovered flowing water on Mars. Limbaugh’s a right-wing radio host, who’s been fouling the airwaves with his views about liberals, socialists, communists, gays, feminists, anti-racism activists and so on since the 1980s. He sneered at NASA’s announcement because – wait for it – the agency was part of a ‘leftist’ plot to promote global warming!

Not only does he not understand the science, nor the reality of global warming, I don’t think he knows anything about NASA. I know quite a few people, who are fans of space exploration and research from across the political spectrum, including Conservatives. None of them have ever considered that the space agency was ‘left-wing’, although some of its leading scientists and advocates, like Carl Sagan, were. And the accusation that the agency’s data on global warming is faked for political purposes is risible.

But this shows the contempt Limbaugh has for science, and for education generally.

Florence, one of the many great commenters on this blog, has a background in microbiology and has been very interested in the question of life in space. She has posted a long comment to my piece. I recommend that you read all of it. But the end is particularly important, as she wonders how we got to this point where science is so despised.

And of course, back to NASA. I was fairly sure the alt-idiocy had already “proven” it was part of the deep state and the heart of black ops and skunk works and a branch of the CIA. These latest revelations only serve, as you say, to illustrate the total lack of education to an acceptable level in this day and age, more worryingly the lack of scientists in government in the USA and across the world. The charge against the scientific community lead by Trump and his “business men” ilk, with the violent and thuggish self styled fascist enforcers and militias coming out the woodwork in the last year, make the premise of the Handmaids Tale seem worryingly prophetic. How did this happen?

I think it’s part of a general distrust of intellectuals in American culture, which has increased massively amongst Republicans in recent years. In the piece below, The Young Turks discuss the finding that a majority of Republicans and Republican-leaning people distrust college education. They also note that they don’t just look down on higher education. They also hate and distrust the media and science. 58 per cent of Republicans and Republican supporters state that colleges and universities have a negative effect on the country, compared to 45 per cent a year ago, in 2016.

Cenk Uygur suggests that part of this is the use of propaganda by the party’s leaders. Part of the problem is that Conservatives tend to be more authoritarian than left-wingers. Thus, they’re more likely to follow the opinions of their leaders, and in the case of the Republican party, these leaders despise higher education.

Ana Kasparian, his co-host, who I believe teaches political science herself, argues that it’s because the Republicans want to keep you stupid. They’re trying to privatize education, and get children instead to attend private schools through voucher schemes, where the normal educational standards do not apply. There’s more than an element of hypocrisy in this. Those public figures trying to destroy the American educational system and minimize the benefits of higher education are themselves highly educated. Many of them have gone to Ivy League universities. Anne Coulter is one example. In her book, which Kasparian laments she has had to read, ’cause she’s got to debate her, Coulter states that the only purpose of college education is to produce ‘social justice warriors’. Yet this woman went to Cornel. Yet education is one of the great indicators of how well an individual will do in the future. And as she points out, it also protects you from scams.

Yet the Republicans themselves are also slightly divided on the issue of the benefits of higher education. 46 per cent of Republicans earning less than $30,000 a year say that college has a beneficial effect on how well you do. This declines for those earning over $30,000 all the way down to 32 per cent.

Uygur and Kasparian admit that there are caveats and qualifications to this issue. Higher education has a down side, in that students are saddled with an immense amount of debt. This needs to be reformed. But Republicans don’t see college as a negative because they feel sorry for the students burdened with this debt. No, they want to keep people stupid and misinformed, so they don’t climb the economic ladder and they can’t fill them with some of the nonsense they believe.

Uygur concludes ‘So don’t go to university, because if you go to a real university, you might not go to a Trump university, and that would be bad for Trump.’

Once again, this is an American issue that applies almost in toto to Britain. Continental visitors and emigrants to Britain have commented on how anti-intellectual British society is. And this anti-intellectualism is again part of British Conservatism as well. Way back in the 1980s Private Eye reviewed a book on Conservative by the right-wing British philosopher, Roger Scruton. Scruton declared that Conservativism wasn’t an intellectual force, but was largely unspoken, and based on the power of tradition. For which the reviewer thanked Scruton for being honest about how anti-intellectual it was. Intellectuals and science are distrusted, because many of their findings contradict or cast doubt on traditional attitudes. For example, feminism attacks traditional notions of gender roles. Black and Asian intellectuals and activist have also undermined commonly held racial assumptions about White superiority and the subordinate role of their ethnic groups. Left-wing historians and political scientists have also challenged the class basis of western, including American and British society, as well as the supposed beneficial nature of western imperialism.

Some of the Republican distrust of science comes from Biblical literalism. The findings of geology and cosmology contradict a literal reading of the creation of the world in Genesis. That said, one study found that the people, who had the greatest faith in science were actually Creationists.

The Republicans and some of their British counterparts, like Nigel Lawson, also deny the reality of global warming. Hence Trump’s decision to close down that part of the federal government that researches and publishes studies of climate change and the pollution and decline of America’s epic natural beauty. It’s why Theresa May and Dave Cameron get annoyed whenever anyone shows how terrible fracking is for local people and the environment.

Science can be particularly difficult for the layperson to understand. It can involve very careful statistical analysis of complex data. And some of the raw phenomena are extremely weird. Quantum physics is a case in point. The world of subatomic particles is contradictory and very different from the macroscopic, everyday world. Subatomic particles dart into and out of existence in the quantum foam at the very lowest layer of matter. Light can be simultaneously a wave and a particle. Particles may be in two places at once, under their position is recorded by an observer. They can also move between one place in the atom to another without physically crossing the space in between. And two entangled atoms can behave as one, even though they may be separated by light years. It’s so bizarre that the scientists studying it have said that ‘you don’t understand it. You just get used to it.’

Also, some of the pronouncements made by intellectuals themselves have given critics ample ammunition. Like the statement by one professor a few years ago that snowmen were racist and sexist. Or the £20,000 in grant one scientist received for researching the terribly important issue of why cornflakes get soggy when you pour milk on them.

There’s also the problem that scientific opinion also keeps changing on medical matters. Every so often researchers discover that certain foods are harmful for you. On the other hand, certain others are beneficial. Only for these opinions to be revised a few years later.

But the nature of science is that it is a process, not a set body of knowledge, and that it’s conclusions and statements may be revised as and when later discoveries are made. It’s why no-one now believes that an immaterial fluid – the ether – permeates the universe, with atoms only whirlpools in it, as they did over a century or so ago.

And so the right-wing press, like the Scum all the way up to the Torygraph, and particularly the Daily Heil, will publish endless numbers of articles attacking ‘left-wing’ intellectuals. Paul Johnson, the Conservative pundit, who used to write for the Daily Mail and Spectator, amongst other rags, wrote a book on them. Entitled Intellectuals, Johnson used it to explore what right intellectuals had to tell us what was right and how to order our lives. Private Eye also reviewed this as well. You will not be surprised to read that most of the intellectuals Johnson wrote about were left-wing, and many of them had shabby personal lives. Karl Marx is one example. Others were gay, or otherwise had colourful sexual tastes, like Kenneth Tynan, who apparently was into S&M.

But none of this actually refutes the value of their work, which has to be judged on other terms. Marx’s own bad behavior as a man doesn’t contradict his philosophical and economic theories any more than Alan Turing’s homosexuality refutes his work on mathematics and computers. But this doesn’t stop Johnson trying to tell you that their own bad behavior disqualifies intellectuals from having the right to explore how society may be improved. An attitude that, incidentally, is apparently shared by that other Johnson, Boris. This should rule Boris out as well as a serious politician, if true.

In the meantime, don’t let the Tories and Republicans run down public education. And stick up for proper intellectuals and intellectual discourse. As someone once said, ‘Eggheads of the world, unite! You have nothing to lose but your brains.’

Rush Limbaugh: Evidence of Flowing Water on Mars Is Leftist NASA Plot

August 20, 2017

Here’s another right-wing gasbag, who should lose his radio show. In this clip from two years ago – 2015 – host Sam Seder of The Majority Report comments on Rush Limbaugh’s pronouncements about signs of flowing water on today’s Mars by NASA. NASA announced that they had found evidence that water still flows today on the Red Planet at the right season. The space agency states that this is a survivor from the period, 3 billion years ago, when the planet was much warmer and wetter than today, and a great ocean may have covered the entire northern hemisphere. The discovery is of immense importance in the search for possible life elsewhere in the solar system.

This is science, but it’s too much for Rush Limbaugh, who sees a conspiracy where there is none. NASA is part of the leftist plot to delude the world into believing in global warming, and this announcement, he goes on to suggest, may be part of it. He ridicules his producer, Sneedley, who was excited and enthusiastic about NASA’s announcement. Limbaugh then declares that he is a ‘big time science guy’ who gone past ‘science 101’. He then goes on to cast scorn and suspicion about the announcement. It’s part of some leftist plot being pursued by the agency, but he doesn’t quite know what yet. But it’s probably about global warming. Soon, he predicts, they’ll announce that they’ve found a graveyard.

Limbaugh’s a Republican broadcaster, who’s been a fixture of American right-wing radio since the 1980s, loudly applauding Ronald Reagan and ranting about how the ‘Leftists’ are trying to destroy his country. In the clip, Seder and his co-hosts and producers ridicule Limbaugh not only for his scientific ignorance – what, pray, is ‘Science 101?’, as well as the way he has openly sneered at and belittled his producer.

They then conclude the programme by further mocking him. They imitate Obama’s voice to declare that Islam is the one true religion. The Martians rejected this, which is why they were hit by a devastating drought. That’s why Obama is going to declare shariah law, and have a child from every White family in the mid-West sold into slavery in the Middle East.

This is to poke fun at Limbaugh, and the stupid, paranoid opinion amongst many American Republicans that Obama is a secret Muslim advancing the plans for an Islamic takeover of the US.

The clip shows much of what’s wrong with the American right’s attitude to science, their massive ignorance, which they think shows how perceptive they are, and their stupid paranoia about ‘leftists’. Which in this case, means anything and anyone, who isn’t as crazily right-wing as they are.

I’ve put up several pieces here about the possibility of life on Mars, and the use of certain genetically modified organisms to terraform the Red Planet. I know that several of the readers of this blog have science backgrounds and similar interests. I’ve put this up because I thought people might like to see just how stupid and ignorant Limbaugh, and by extension, his audience, is about this whole issue.

Firstly, as Seder points out, when NASA made the announcement they said it was about the state of Mars 3 billion years in the past. It’s nothing to do with global warming.

Absolutely correct. Planetary scientists now believe that there was a period during the early history of the solar system, when Mars was warm and wet. I think the National Geographical mentioned this when they did a piece on Mars in the 1980s or ’90s. It’s also discussed in Kim Stanley Robinson’s epic SF novel about the colonization of Mars, Red Mars.

What killed Mars was not global warming, but global cooling. Mars has no tectonic plates, and so it is theorized that the planet’s atmosphere was not renewed through releases of gases released from its rocks through geological forces. Over millions or billions of years, the atmosphere evaporated into space. The surface pressure is about 5 milibars – that of a laboratory vacuum. Without an atmospheric blanket to focus and increase the sun’s light, the planet cooled. Without atmospheric pressure to sustain it, water rapidly sublimates into vapour on the Martian surface. What water has survived is locked up in the ice caps, and may be as permafrost below the Martian surface.

Mars has never been cited as a warning of the dangers of global warming. That’s always been Venus. Venus lies closer to the Sun than Earth, and so has suffered runaway global warming as ever increasing amounts of carbon dioxide was released from its rocks. The result of this is that the planet is covered by a permanent cloud layer. Surface temperatures reach something like 400 degrees C, the rain is sulphuric acid, and its surface pressure is enough to squash a human flat. If you want an example of how different the histories of Mars and Venus are, go have a look, or read, the chapter ‘Blues for a Red Planet’ in Carl Sagan’s Cosmos. Sagan was a major believer in the threat of global warming, and in that episode of his epic science history blockbuster, explicitly drew a parallel between Mars’ fate and that of our own world, if we don’t cut carbon emissions.

As for finding a graveyard on Mars, some scientists have speculated on the possibility that we may find fossils of the creatures that may have lived on Mars, far back in ancient geologic time. There are also serious scientists, who have suggested that we should look for evidence of advanced extraterrestrial civilisations in the planets of our solar system. Our solar system lies in a part of the Galaxy, where the stars are an average of a single light year away from each other. That’s a short enough distance for an advanced civilization to make the difficult journey across interstellar space to another solar system. And the solar system is so old, about 4 billion years if not more, that it is statistically likely that intelligent life has arisen elsewhere in our Galaxy. And just as the Earth orbits the Sun, so the Sun orbits the centre of the Galaxy, taking 225 million years to complete one revolution. This is long enough for our Solar system to have come close to one of those other stars, harbouring alien life.

So signs of an extraterrestrial civilization may well exist on Mars. However, Mars has been dead for so long, that it’s unlikely that there exist any remains of an indigenous Martian civilization on the planet’s surface. In their entry ‘The Surface of Mars’, subtitled ‘Desert’, in their book Catalogue of the Universe, astronomers Paul Murdin and David A. Allen write

If once great cities stood here, they have crumbled to unrecognizable shapes. If trees bowed before moist zephyrs, they have returned to the dust whence they rose. If aircraft landed here, they too have vanished, or been buried beneath unknown depths of sand and rocks. (pp. 205-6).

Not all scientists are convinced that the features NASA suggested was evidence of flowing water were actually produced by it. Others believe that the marks on the surface may instead be produced by the release of other chemicals in liquid form from the underlying rock.

But if liquid water still flows on Mars, albeit it occasionally, not only does it augur well for the possible survival of some life, even if only primitive bacteria, but it also makes the planet more hospitable for possible colonization.

NASA’s claim to have found evidence of surface liquid water was therefore immensely exciting. And Limbaugh’s producer, Sneedley, was actually absolutely right to be excited about it. It’s his host, Limbaugh, who’s ignorant. And dangerously so.

No-one expects ordinary people to be experts on science. Science has advanced at such a rate that it’s too much for many ordinary people to keep update with scientific advances, some of which can be very arcane to laypeople.

But we do need people to be reasonable well-educated. And especially about threats to the planet, like global warming. It’s why there’s a need for good scientific writers and broadcasters to explain the issues clearly.

Limbaugh with his stupid denial of global warming, and his paranoid suspicion that NASA is part of some larger ‘left-wing’ plot, is actually doing the opposite. He’s disparaging real science and trying to keep people ignorant in order to promote his own, extreme right-wing views.

He’s also a danger on racial issues. A day or so ago I reported that Trump had cut funding for FBI and Department of Homeland Security initiatives against White racist terrorism. This included a charity, Life After Hate, that helps former Nazis leave these organisations without being attacked by their fellow stormtroopers. It’s a real danger. Matthew Collins, one of the founders and leaders of the anti-racist/ anti-religious extremism organization, Hope Not Hate, had to migrate to Australia in the 1990s after he appeared in a documentary exposing the violence of the NF and BNP. Obama had given $400,000 to the charity. He would have funded them sooner, but he was prevented from doing so by the ravings and possible denunciation by Limbaugh.

It’s debatable, however, how long Limbaugh will actually carry on. Far from being the influential Republican spokesman he thinks he is, his radio station in recent has been haemorrhaging sponsors and advertisers. His ratings have fallen to the point, where fewer people listen to him than to College radio stations with the range of only one or two miles. The only thing keeping him on air is money from Republican and similar extreme right-wing think tanks. If they pull out, he’s off the air.

Torygraph Journo’s Book on Interstellar Travel Through Artificial Black Holes

August 10, 2017

The Iron Sun: Crossing the Universe through Black Holes, Adrian Berry (London: Jonathan Cape 1977).

No, not the Iron Sky, which was a Finnish Science Fiction film that came out a few years ago, in which the Nazis secretly colonized the Moon, and fight an interplanetary war with an America governed by a female president, who bears a certain similarity to Sarah Palin. This is the Iron Sun, a book in which Telegraph journalist Adrian Berry explains his theory that it should be possible to explore space using artificial Black Holes to travel faster than light. Berry was a Fellow of the Royal Astronomical Society, a Senior Member of the British Interplanetary Society, and a member of the National Space Institute of America. According to the potted biography on the back flap of the dust jacket, he also covered two of the Moon Landings from Cape Kennedy and Houston. Along with this book, he also wrote The Next Ten Thousand Years and The Great Leap.

The latter book was published in the 1990s, and is also about interstellar travel and exploration. It’s a good book, though marred by Berry’s Libertarian politics. Towards the end of the book, he devotes an entire chapter to argue for Von Hayek’s daft and destructive economic ideas. So did a number of other space and extreme technology groups at the time. The transhumanists, the crazy people, who want to transform themselves into cyborgs, explore the Galaxy, and ultimately achieve immortality by uploading themselves into computers, were also very much into Von Hayek and Libertarianism. I have a feeling that this has gone by the way now. A friend of mine, who was also into it, told me a year or so ago that the Austrian economist is rather passe now. One of the leaders of the movement has said that Hayekian economics was just something they were into at the time, and they’re now distancing themselves from him, so that his ideas aren’t synonymous with the movement as a whole.

In this book, after taking the reader through Einstein’s Theory of Relativity and explaining what Black Holes are, Berry then advances his book’s central idea. This is that humanity will be able to use a fleet of automated Buzzard ramjets as cosmic bulldozers to create an artificial Black Hole of a particular size one light year from Earth. The Buzzard ramjet was a type of spaceship devised in the 1970s. Instead of taking its fuel with it into space, like conventional rockets and spacecraft, the ramjet would scoop up the necessary hydrogen for its nuclear fusion engines from the surrounding interstellar medium, in the same way that a high-performance ram jet sucks in the air it needs to reach supersonic velocities from the Earth’s atmosphere. It was an immensely popular idea amongst space scientists, SF fans and advocates of the human colonization of space, as it appeared a practical way of creating a spacecraft that could reach the very high speeds approaching that of light needed to cross space to the nearest stars within a few years, or tens of years, rather than centuries and millennia.

Berry believed that strong electromagnetic fields could be used to collect and push the necessary hydrogen atom ahead of the spacecraft. Once in place, the hydrogen and other gaseous material would be forced together into a single mass, until it was so large that it collapsed under its own gravity, forming a Black Hole.

It was Carl Sagan, who first suggested the possibility of using Black Holes as cosmic subways to travel across the universe faster than the speed of light. Einstein, Rosen and other scientists hypothesized that the gravity inside Black Holes was so massive, that not only did it crush matter out of existence, but it also created a wormhole through space and time to, well, elsewhere. An object, including a spaceship, could enter a Black Hole to travel through the wormhole, to exit from a White Hole somewhere else in the universe, or even in a different universe altogether.

The Black Hole would be built a light year away, as this would be a safe but accessible distance. The construction ships would be automated as they would not be able to pull back once construction of the Black Hole was underway, and would be allowed to fall into it.

Berry admits there is one problem with his scheme: no-one knows how far away, nor in what direction, the resulting wormhole would extend. He therefore argues that the first astronauts to use the new wormhole would also have their own fleet of construction vessels, in order to build another Black Hole at their destination, which would create the White Hole needed for them to return to the Solar System. The process would take about forty years.

He explains the details of his proposal in a fictitious interview. There’s also an epilogue, and three appendices, in which he gives further information on Black Holes, including the navigable apertures created by Black Holes of varying sizes.

It says something for the optimism about the future of spaceflight in the 1970s that Berry considers that we should have the capability to do all this sometime around 2050. The 1970s were the decade when it seemed almost anything was possible after the Moon Landings, and astronomers and writers like Sir Patrick Moore seriously predicted that by now we’d have bases and colonies on the Moon and Mars, holidays in space, orbital habitats at the L5 points, as suggested by Gerald O’Neill, and would be gradually expanding into the rest of the Solar System.

If only that had happened!

Despite the formation of public groups, like the Mars Society and the Space Frontier Foundation, for the colonization of space, humans so far seem stuck in Low Earth Orbit. There have been plans over the past few years for crewed missions to return to the Moon, and to Mars, but these haven’t materialized. NASA is planning an expedition to the Red Planet in the 2030s, but I’m really not confident about that every happening. And if it’s a struggle for us to get to Mars, sixty or seventy years after the Moon Landings, it’s going to be impossible for us to build a Black Hole.

Part of the problem is the difficulty of building a viable Buzzard ramjet. After the idea was proposed, someone worked out that the interstellar medium was so rarified that the vehicle would need a ramscoop 3,000 miles long to collect all the gas it would need. I’m not sure if this makes it completely impossible – after all, firms like the Hanson Trust back in the 1980s tried selling themselves to the general public with commercials telling the world that they made enough plastic chairs to go round the Earth so many times. And it might be possible to develop superlight materials for the scoop so that it would not be impossibly heavy. Such a material would similar to the mylar suggested for the solar sails for the Starwisp mission. This is a suggested mission to send a 50 kilo instrument package to Alpha Centauri in a journey lasting thirty years or so. And the construction of a space elevator, which would have to be of a light material strong enough to take the weight of cable cars and carry them tens of thousands of mile into space out of the Earth’s gravity well seems to me to present even greater problems. But even if a ramscoop of that size isn’t impossible, it would be very, very difficult and extremely expensive.

Not all scientists are convinced that it should be possible to use wormholes in this manner anyway. Philip’s Astronomy Encyclopedia state that one particular type of Black Hole, rotating Kerr Black Holes, which don’t have the singularity that eventually destroys all the matter passing through it, ‘have fascinating implications for hypothetical space travel to other universes’. (‘Black Holes, p. 57). However, the entry for ‘Wormholes’ states that, although they’re predicted by Einstein, ‘such wormholes cannot exist in reality, since the occurrence of white holes is forbidden by the second law of thermodynamics.’ (p. 440). On the other hand, Russian physicists have shown that it’s possible to create a wormhole a few light years in extent, though this would take more energy than is currently available in the universe.

I hope that it may one day be possible to construct such wormhole subway routes through the cosmos, as suggested by Sagan. I also wonder if the book may also have influenced comic writer Pat Mills in the creation of the Black Hole and White Hole bypasses for Termight – Earth thousands of years in the future – in the Nemesis the Warlock Strip in 2000 AD. This was an artificial Black Hole and its White Hole counterpart, constructed by Earth’s engineers to provide instantaneous access to space. ‘Nemesis the Warlock’ appeared about 1979, and while it’s definitely Science Fantasy, Mills actually did some reading in science as research for the comic. He said in an interview nearly four decades ago that he shocked the comic’s management because he bought a whole stack of books on science and then invoiced the comic company for them as research. He was annoyed that the attitude to comics at the time was so low, that the idea of doing basic research for them was looked upon with horror. Ah, how things changed after Frank Bellamy and ‘Dan Dare’. Bellamy’s studio for Britain’s greatest space hero, with the exception of Judge Dredd, included a model maker and researchers. Unfortunately, this was all cut away as an unnecessary expense when the Eagle changed hands. Sales had fallen, and the comic was then making a loss. Hence the decision to cut down the number of staff in the studio. But it does show the initial commitment to quality of strip’s creators, and Dare and Bellamy’s superb artwork are still admired as one of the greatest pieces of British comic art and literature.

Two ‘Super Earths’ Discovered around Nearby Star, Tau Ceti

August 10, 2017

Today’s I newspaper, for Thursday 10th August, has the news that two planets, which may be suitable for human colonization, have been found around Tau Ceti, a nearby star similar to our Sun.

The paper says on page 2

Astronomers have discovered two potentially habitable “super-Earths” orbiting a star 12 light years away. British led experts have identified four rocky planets, similar in size to Earth, in Tau Ceti’s “habitable zone” orbiting the nearest Sun-like solar system, neighbouring ours.

John Von Radowitz’s article, The Climate’s Nice 12 Light Years Away on page 5 also adds that the two ‘super-Earths’ are at the edge of Tau Ceti’s “habitable zone”, and that

British-led astronomers speculate that the system might be a potential candidate for future interstellar colonization. But there is evidence of a massive debris disc circling the star, increasing the chances of the planets being pounded by asteroids and comets.

Dr. Fabo Feng, the lead researcher from the university of Hertfordshire, said: “We’re getting tantalizingly close to observing the correct limits required for detecting Earth-like planets.

“Our detection…is a milestone in the search for Earth analogues and the understanding of the Earth’s habitability.”

The findings are to be published in ‘The Astronomical Journal’.

Philip’s Astronomy Encyclopedia (London: Philips’, 2002) states that Tau Ceti ‘is the most Sun-like of all the nearby single stars’. (‘Cetus’, p. 81), and that it is a G8-type star lying at a distance of 11.9 light years. This means its a yellow dwarf star like our Sun.

Tau Ceti is one of the stars making up the constellation Cetus, and is quite visible, unlike some of the other nearby stars, like Barnard’s Star. It’s so much like Sun that it was one of two stars, the other being Epsilon Eridani, which were the subject of Project Ozma in 1960. This was a program led by Frank Drake, using the 26 metre radio telescope at Green Bank to listen for possible signs of alien civilisations broadcasting messages along the 21 cm band. That wavelength was selected because it’s close to the wavelength occupied by the noise of cold hydrogen in space. Drake and his fellow scientists believed that it would therefore be a natural wavelength for advanced alien civilisations to use to broadcast to each other across the vast gulfs of space.

The search was, however, unsuccessful, and after a couple of months it was discontinued. Frank Drake still remains an influential figure in the Search for Extra-Terrestrial Intelligence (SETI) for his formulation of the Drake Equation, a formula which allows the number of possible alien civilisations in our Galaxy to be calculated.

The Equation has also come under attack. James E. Oberg, a NASA scientist, criticized it over thirty years ago in his article, ‘New Case Against Extraterrestrial Civilisations’ in the 1981 Yearbook of Astronomy. Part of the problem with the equation is that no-one actually knows how common Earthlike planets are, nor how likely the emergence of life is, and how like intelligent, technological life is either. According to the numbers selected, the Equation gives an answer for the number of alien civilisations in our Galaxy as anywhere from several to several million. I have a feeling Carl Sagan, one of the greatest advocates of the search for alien life, believed that there may have been around a thousand or so extraterrestrial civilisations out there in our Galaxy.

Astronomers have since found many tens, if not actually hundreds of extra-solar planets since then, some of which are rocky worlds like our own. This is very encouraging for SETI advocates and researchers, but later projects to search the sky using radio telescopes have still not found any conclusive evidence of alien intelligence.

As for missions to neighbouring stars, the costs of constructing a suitable spaceship that will get there in decades, rather than centuries or millennia, is immense. However, it has been estimated that the global economy should have grown sufficiently to make such a mission affordable by the 22nd Century A.D. Always supposing that Donald Trump and Kim Jong Un haven’t destroyed the world before then.

Apollo Astronaut Michael Collins on Sexism, the Fragile Earth and Banning Guns in Space Colonies

July 13, 2017

Last week I put up a post about a clip of Buzz Aldrin, the second man to walk on the Moon, pulling faces at a rambling, incoherent speech made by Donald Trump. Trump was signing into law an act affirming America’s commitment to the space programme. His speech about it was less than inspiring however, and Aldrin, who not only went to the Moon himself, but has also been a staunch supporter of opening the High Frontier up to ordinary women and men, was very definitely less than impressed.

One of the books I’ve been reading recently was Flying to the Moon: An Astronaut’s Story, written by the third member of the Apollo 11 crew, Michael Collins. Collins was the pilot, who flew the Apollo spacecraft to the Moon, and then waited in lunar orbit while Armstrong and Aldrin made their historic landing, before flying back with them on the return journey to Earth. The book is Collin’s account of how he came to be astronaut. Determined to be a pilot after being allowed to hold the joystick of a passenger aircraft on which he and his family were travelling as a child, he joined the USAF and became a test pilot. He then moved on to join NASA’s space programme. He describes the rigorous training required, and his first flight into space with John Young in Gemini 10 in July 1966. He also explains how he came, reluctantly, to leave the astronaut programme for a variety of reasons, not least was the way it was stopping him from spending time with his family. And in his final chapter he, like Aldrin, looks forward to the future spread of humanity throughout the Solar system and beyond, with humans going to Mars and then Titan, a moon of Saturn, which may hold the key to the origin of life.

This isn’t an explicitly political book. Nevertheless, Collins does comment on specific issues as they affect the racial and gender composition of the astronaut programme, his perspective on the importance of the environment and why he believes guns would be banned by the inhabitants of a space colony. These are all issues which Trump, his supporters and donors in the gun manufacturers and lobbyists would strongly oppose.

In the passage where he discusses how he and the other astronauts became part of a panel, whose job was to select a fresh batch of astronauts, makes a point of explaining why only white men were selected. He then goes on to comment that although this was what was done at the time, he believes and hope that this will change, and that Blacks and women are just as capable of flying air- and spacecraft equally well. He points out that the highly technological nature of modern aircraft means that there is absolutely no biological obstacle to women piloting such high performance machines. He writes

Note that I have said “he”, because there were no women in the group, nor where there any blacks. In thinking about that, it seems to me that there were plenty of women and blacks who could get the highest marks in categories 1 and 4 [their intelligence and how badly they wanted to be astronauts], but in 1966 categories 2 and 3 [education and experience] tended to rule them out. There simply did not seem to be aeronautical engineers and experienced test pilots, who were black or women. I think, and hope, that will change in the future. Flying a modern jet aircraft does not require a great deal of strength, for one thing. Hydraulic flight controls, like power steering in a car, prefer a light touch, and women should do as good a job as men. Obviously, an airplane has now way of telling the skin colour of the person flying it. (pp. 72-3. My comments in brackets).

He describes how looking at the Earth from space made him aware how fragile it was, and of the importance of preserving the environment.

I will never forget how beautiful the earth appears from a great distance, floating silently and serenely like a blue and white marble against the pure black of space. For some reason, the tiny earth also appears very fragile, as if a giant hand could suddenly reach out and crush it. Of course, there is no one giant hand, but there are billions of smaller hands on earth, working furiously to change their home. Some of the changes being made are good, and others bad. For example, we are learning more efficient ways of catching fish, and that is good because it means more people can be fed from the oceans. If, on the other hand, these new methods result in the disappearance of species, such as whales, then that is bad. The automobile gives us great mobility, but pollutes our atmosphere. We cook cleanly and efficiently with natural gas, but we are running short of it. Newspapers and books spread knowledge, but require that trees be chopped down. It seems that nearly every advance in our civilisation has some undesirable side effects, Today’s young people are going to have to acquire the wisdom to see that future changes help our planet, not hurt it, so that it truly becomes the beautiful, clean, blue and white pea it seems to be when viewed from the moon. The earth truly is fragile, in the sense that its surface can easily shift from blue and white to black and brown. Is the riverbank a delightful spot to watch diving ducks, or is it lifeless greasy muck littered with bottles and tires? More people should be privileged to fly in space and get the chance to see the fragile earth as it appears from afar.
(p. 146).

Further on in the book, he states that future orbiting settlements would get their power from solar energy, as this would not only be abundant and free, but also clean, unlike coal. (pp. 150-1).

He also remarks on the way the Apollo missions differed from previous historic expeditions in that the explorers were unarmed, and suggests that the future inhabitants of a space colony at one of the libration points where the gravity of the Earth and Moon cancel each other out, and so named ‘Libra’, would similarly see no need for carrying weapons.

Apollo set a precedent for the future in another interesting way. It was probably the only major human expedition in which no weapons were carried. In similar fashion, no weapons would be permitted on Libra and Librans simply would not be able to understand why earth people continued to shoot one another. On Libra, if people felt hostile, they would be urged to put their energies into athletic contests or other competitive events, or simply to let off steam by going flying.

He then describes how the lower or zero gravity in the colony would allow people to fly aircraft power by their own muscles. (pp. 154-5).

Most of this is, or at least should be, non-controversial. Scientists have been warning us about the immense danger to our ecosystem, and the horrific decline in its natural wildlife as more and more habitats are destroyed, and an increasing number of species threatened with extinction, since the early ’70s. Among those warning of the ecological perils to the planet was the inspirational astronomer and NASA scientist, Carl Sagan. And indeed, one of the most powerful images that stimulated ecological awareness and the burgeoning Green movement was that picture of the Earth as a fragile, blue orb hanging in the blackness of space taken from the Moon by the Apollo astronauts. Way back in the mid-1990s the Beeb’s popular science programme, Horizon, devoted an edition, ‘Icon Earth’, to how this photo had influenced politics and culture.

The picture hasn’t just made more people aware of the urgent need to protect the environment. Some of the astronauts have spoken about how it brought home to them how artificial racial and national divisions are. They point out that there are now boundaries visible from space. Helen Sharman, the British astronaut who flew with the Russians to Mir in the 1980s, states in her book about her voyage that space helps to foster international understanding and cooperation. She observes that astronauts are the least nationalistic people.

As for guns, it doesn’t take much imagination to realise that shooting in the enclosed environment of space habitat could have truly disastrous consequences through the damage it could do to the machinery and fabric of the colony itself, and their ability to preserve human life in the harsh environment of space. A bullet through the outer skin of a spacecraft could lead the escape of its air, causing those within to die of suffocation and decompression.

Trump, however, is supported by the racist and misogynist Alt Right, who would like to roll back Black Civil Rights and women’s social and political gains since the 1960s, while the Republican party as a whole is generously funded by the NRA and the gun lobby, and the Koch brothers and other industrial magnates. The Koch brothers own much of the American petrochemical industry, and so, like many of the other multimillionaire businessmen, are very strongly opposed to any kind of environmental protection. The Kochs in particular are responsible for closing down awkward parts of the American meteorology and environmental science laboratories when they dare to issue warnings about the damage industry is causing to the country’s natural beauty and wildlife. They are then replaced with other institutions, also funded by the Kochs and those like them, which then conveniently deny the reality of climate change. The Republicans and their supporters in industry have also set up fake ‘astroturf’ Green movements, like Wise Use, which seek to undermine the genuine environmental movement.

Given the way the experience of looking back at our beautiful planet from space has transformed political, social and cultural perspectives all across the world, you can understand why some astronauts just might feel they have excellent reasons for pulling faces at their president.

Stephen Hawking and Other Celebs Urge Public to Vote Labour

June 6, 2017

Mike over at Vox Political has put up a piece reporting that Ricky Gervaise, Dr Stephen Hawking and Mark Ruffalo, the actor, who played Dr. Bruce Banner, the alter ego of the Incredible Hulk, have all urged the public to vote Labour on Thursday.

Gervaise issued a Tweet stating he wasn’t telling people which way to vote, but it was a fact that the only way to keep the Tories out was to vote for Jeremy Corbyn.

Mark Ruffalo stated that he humbly endorsed Jeremy Corbyn, as he offers people an alternative to the corporate status quo, which never ends well for people. This prompted John Prescott to Tweet ‘Hulk smash Tories’.

Indeed he would. Banner and the Hulk in the original Marvel comics were profoundly countercultural figures. The Hulk was anger incarnate, born in the radiation blast of an American nuclear test when Banner tried to save teenager Rick. And Rick was very much a ‘rebel without a cause’, a youth, who’d driven into the test zone, heedless of his own safety, because he didn’t feel society had anything for him.

While Banner was very much a square, whose girlfriend was the daughter of the commanding officer in charge of the test, the tenor of the strip was very much anti-militarist. The commanding officer hated the Hulk, and had resolved to destroy him. The Hulk, however, really only wanted to be left alone, and so one constant theme was the running battle between the Hulk and the US army. Ang Lee’s film version of the strip, which unfortunately flopped, got this part of the Hulk’s characterisation absolutely right. And in the 1970s, the anti-militarist message of the strip became stronger. In one story, for example, Banner discovered and did his best to oppose dehumanising military experiments to link soldier’s brains to battle robots, experiments that had resulted in the troopers themselves feeling robotic and mechanical.

The influence of the Vietnam War in dehumanising a generation of American young men, to turn them into ruthless monsters responsible for horrific atrocities, is shown very clearly here.

And one real-life physicist, who has also come out for the Labour party is Cosmologist Dr. Stephen Hawking. Hawking told the Independent and the Mirror that he was voting Labour, because another five years of the Tories would be a disaster for the NHS, the police and other public services.

His endorsement has been welcomed by people like Dr. Alex Gates. Hawking is best known for his book, A Brief History of Time, though his background is in Black Holes. Dr Hawking even has a variety of radiation named after him. Black Holes, or rather the Event Horizons around them, are gradually evaporating, and the radiation they give off is called ‘Hawking Radiation’.

And so Dr. Gates quipped that Hawking had spotted the Black Hole in the Tories’ NHS budget.

One space scientist, who I feel would definitely have supported Jeremy Corbyn over here and Bernie Sanders in his own country, is Dr. Carl Sagan. Older readers of this blog may remember Sagan from his TV blockbuster history of science, Cosmos, and his SF novel, Contact, which was turned into a film with Jodie Foster as the astronomer heroine, who travels through a wormhole to make contact with an alien civilisation.

I very definitely don’t share Sagan’s views on religion. He was a religious sceptic and a founding member of CSICOP. But he was also a man of the Left, who hated imperialism and militarism, and supported the burgeoning Green movement. In the 1980s he warned that a nuclear war would result in a devastating global ‘nuclear winter’ of the type created by the asteroid that wiped out the dinosaurs 65 million years ago.

It’s since been shown that this wouldn’t actually occur. But Sagan was right to press for nuclear disarmament, and absolutely right to oppose the new Cold War Reagan and Maggie Thatcher were trying to whip up against the Russians.

He was also critical of the design of the space shuttle. This was supposed to be the vehicle that would open space up to just about everyone, provided you were fit enough to stand the three Gs of acceleration into orbit. The Challenger disaster put an end to that.

Sagan informed the public that the original design for the Shuttle had been for a smaller vehicle, which would have been purely civilian and much safer and more effective. However, the American military had stopped this, because they wanted a larger vehicle to carry their spy satellites. The result was the over-engineered machine, which exploded at least twice, and whose launches had to be cancelled because of engineering problems.

Sagan died of prostate cancer in the 1990s. He was a brilliant scientist and visionary, who speculated about life on Mars and Venus, and, like Hawking, was a staunch advocate of the colonisation of space. And he was inspiration to a generation of young people to have an interest in space and science. One of the most obvious examples of this is Dr Brian Cox, who freely acknowledges Sagan’s influence.

One feels that Sagan would have firmly resisted everything Bush, Blair, and now Trump, Cameron and May have done to destroy the environment and spread carnage around the world through their wars in the Middle East, quite apart from the Trump’s administration hatred of mainstream science.

You don’t have to use Sagan’s ‘spaceship of the imagination’ to travel light years to see the immense harm Theresa May and her party have inflicted on the NHS, the public services and our national security.

And you don’t have to be a great scientist to realise that the Tories’ attacks on education – their spending cuts, privatisation of schools, and burdening students with tens of thousands in debts – will stop the country’s young people fulfilling their academic potential, regardless of the bilge they may spout about encouraging the STEM subjects.

And I think Hawking has spoken out about the dangers of May’s cuts to science funding and research.

The only party that is ready to undo all of this is Labour.

So please, vote for Corbyn on June 8th.
