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.

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.

Conspiracy Theorist Alex Jones Claims NASA Operating Child Slave Labour Base on Mars

July 1, 2017

More madness from the very warped mind of Alex Jones. Jones is the head honcho behind the internet conspiracy theory show, Infowars, and its companion website, Prison Planet. Jones believes, or affects to believe, that the American government, the UN, the ‘globalists’, the elite and liberals, Socialists and feminists are engaged in dire and foul conspiracies against the world and its people, and particularly those in America.

Over the years he has claimed that the richest 1 per cent of American society and industry, or at least their menfolk, sacrifice children in Satanic rituals at their annual secret meetings in Bohemian Grove in California. The Twin Towers collapsed because of a conspiracy by the American government, and not because Saudi-backed terrorists hijacked and flew two planes into them. President Obama was going to use to the legislation permitting the establishment of refugee camps to house disaster victims to seize power and herd people into what were really concentration camps. Humanity and the world were under attack by evil extradimensional entities, who might be demons or simply alien intelligences. And Barack Obama was fully under their control. He was truly the Devil’s emissary, because, apparently, he looked demonic, smelt bad and flies were always hovering around him.

Ditto Hillary Clinton. She was also under Satanic influence. She was part of a vast, paedophile conspiracy supplying children to leading politicians from a pizza parlour in Boston. She was also some kind of robot or cyborg, because something metal fell out of her trouser leg when she had a fainting fit during her campaigning. When she momentarily had some kind of problem swallowing a glass of water, Jones seized on this as evidence that she was either demonically possessed, or carrying some kind of alien spawn, which was about to come bursting out of her like the xenomorphs in the Alien movies. She was herself also a participant, with Bill, in black magic ‘spirit eating’ orgies put on by a performance artist.

The UN, Socialists and feminists are all engaged in some weird plot to take over the world and enslave everybody in it, particularly White men. Gay and transgender rights activists are a ‘transhumanist UFO cult’ to create a new, genderless, form of humanity.

How much of this Jones actually believes is a moot point. His ex-wife was suing him for custody of their children, on the grounds that he was utterly made and it was damaging their kids to see their Dad ranting and raving in the TV studio he has at his home. Jones’ lawyers responded by stating that Jones didn’t believe any of it, and it was all ‘performance art’.

Recently Jones has also been forced to issue apologies to people he has libelled on his programme. Someone took his comments about the pizza parlour in Boston very seriously indeed, and walked into it waving a gun around in order to free the child captives in the basement. There weren’t any children kept prisoner there, in the basement or anywhere else. Fortunately, no-one was shot or hurt in this incident.

Then he was threatened with legal action from the Turkish owner of a Yoghurt factory, who had a deliberately policy of employing immigrants. Many of these were Middle Eastern. Jones claimed that this, entirely respectable businessman, who was another paedophile, and that his employees had been responsible for a series of rapes. The businessman wasn’t, and his employees were also innocent. After being threatened with a writ, Jones ended up making a statement that he was entirely mistaken about it all on air.

Now he’s done the same to NASA. On Thursday, Jones had on his programme Robert David Steele, a former Reform Party presidential candidate, who claims to have been a case officer with the CIA. Steele spun a yarn that NASA had been kidnapping children to send them on a 20 year journey to be used as slave labour on Mars. Oh yes, and they were also been frightened and then killed, so that their blood and bone marrow could be harvested for use by the elites. The children had to be terrified when they died as this would enrich it with adrenaline.

NASA responded by denying everything, and pointing out that they didn’t have any kind of child labour camp on the Red Planet.


This story is, of course, absolute nonsense. For a start, 20 years is far too long for a journey to Mars. Spacecraft have to go at a certain speed – escape velocity – to escape the Earth’s gravitational pull if they are to go anywhere else in the Solar system, whether it’s the Moon or the other planets. I think current plans for a Mars mission estimate that it would take about 2-3 years or so to get there. A long time, certainly, but not as long as 20.

Then there’s the logistics and engineering problems of getting people to Mars. You need rockets of a certain size and power. Furthermore, any colonists for Mars, whether free or not, would have to carry all their food, water and air with them. The spaceships will also have to be shielded against cosmic radiation and solar flares. These weren’t much of a problem when going to the Moon, because of the relatively short length of the journey – about a week. Even so, if a coronal mass ejection – a type of massive flare known as a sun storm – had occurred, it would have fried the Apollo astronauts. These are a real threat for those intrepid souls going on the lengthy journey to the Red Planet.

There are also other medical problems caused by the lack of gravity in space. As the astronauts’ bodies don’t have to fight against the pull of the Earth’s gravity, muscles shrink. They also go to the toilet more than they would on Earth, and so start to lose calcium, weakening their bones. Hence their health is monitored, and those crews staying in space for a long time, such as during the Skylab programme from 1973-5, have to devote a certain amount of time each day to doing their exercise.

As there is no ‘up’ or ‘down’ in zero gravity, and the fluid in your inner ear that tells you which is which also starts to float along with the rest of you, some astronauts suffer from ‘space sickness’, similar to the sea sickness some people feel travelling by ship.

There are also psychological hazards that may endanger the lives of the space travellers. I heard Dr Kevin Fong, who’s a specialist in space medicine, talking about them one year at the Cheltenham Festival of Science. Fong pointed out that the strange environment of space can also affect astronauts’ mental health. Several of them have reported hearing sounds, such as dogs barking and babies crying, while in orbit. They can also find themselves doing strange, irrational things, which can potentially kill them, before being snapped out of it. One astronaut aboard Mir described how he was asleep one night, before being suddenly awoken by a noise. He then found one of his fellow astronauts suited up, ready to take a spacewalk. But the poor fellow hadn’t connected the air hoses. It takes about seven hours or so to put on and inflate a spacesuit, so that it protects its wearer from the hard vacuum outside their craft. None of this had been done, and if the astronaut had walked through the airlock, he would have been killed. Fortunately, the other astronaut was able to wake his friends and colleagues, who woke up and managed to stop him.

These are the hazards facing the extremely healthy men and women, who manage to pass the rigorous testing and gruelling grueling training programmes. Hopefully, one day we’ll have learned enough to make space travel sufficiently safe so that families with children can venture into the Deep Black. But we very definitely aren’t anyway near that level now.

This is sheer bullsh*t, and it’s not hard to see where it’s ultimately coming from. Somewhere in there is the influence of Alternative 3. This was an April Fool’s Day joke, broadcast by ITV in 1975. It was a bogus edition of a fake science programme, ‘Science Report’, which claimed that the Earth was dying, and so the Americans and Russians had secretly shelved their differences in order to colonise Mars secretly. Leading scientists were disappearing as they took up their new lives on the Red Planet. Ordinary people, meanwhile, were also disappearing. They were being kidnapped, lobotomised and ‘de-sexed’ to turn them into slaves as ‘batch consignments’, serving their elite masters.

The programme was a hoax, but unfortunately many people were genuinely taken in and didn’t realise that it was a joke. There was also a tie-in novelisation, which until recently was unavailable in the US. This led to rumours that it was all true, and had been deliberately suppressed by Them.

The result has been that a number of other conspiracy theories about secret government space projects have grown up around it, or been inspired by it. This latest nonsense appears to be one of them.

I don’t know how many people actually believe Steele’s story. Possibly very few, the kind of people, who bought into the lurid revelations of Commander X and his tales about secret collaboration with aliens. Or the late Bill English and his rubbish about meeting the Zeta Reticulan ambassador, Omnipotent Highness Krill, at a military base.

I doubt very many people actually believe the story, but that hasn’t stopped Jones having an effect. During the American presidential elections, he gave very vocal support to Donald Trump, who was a guest on his programme several times. He has libelled various blameless individuals, such as the Turkish yoghourt manufacturer. It’s a mercy that his stories about paedophile gangs didn’t result in someone being shot at that pizza place. He also notoriously claimed that the Sandy Hook school shooting was all staged, and that the children and others, who were killed and injured were ‘crisis actors’. This has led to people approaching and accusing the kids’ grieving parents with these claims.

And anti-racist activists are worried about the links Jones and his show have with the racist Alt-Right. This includes his fellow presenter, Paul Joseph Watson, who has inveighed against the threat Islam and Muslim immigration supposedly poses to western civilisation.

Jones is a clown, and his ranting can be hilarious, but there’s a very serious, very dark side to his show. It’s almost the very definition of ‘fake news’, and it is having a pernicious effect on politics in the US, as more citizens are encouraged to fear the terrible, but entirely imaginary Others that mean to harm and enslave them. While, of course, supporting right-wing Libertarian policies, which will deny them proper, decent medicine, welfare support, housing, clean water and education.

Radio Programme Tonight on Bishop Grosseteste’s Medieval Big Bang Theory

June 14, 2017

Science Stories on Radio 4 tonight, `14th June 2017, at 9.00 pm is on ‘The Medieval Bishop’s Big Bang Theory’. According to the short description about it in the Radio Times, the programme’s presenter, ‘Philip Ball tells the tale of a medieval Big Bang Theory forged by Bishop Robert Grosseteste in the 12th century’.

Grosseteste was the 12th century bishop of Lincoln, and was one of the leading figures of the 12th century renaissance. As well as leading English churchman, Grosseteste was a pioneering natural philosopher. In his Hexaemeron, a theological and philosophical meditation on the first six days of creation, according to the story in Genesis, he worked out a theory that is surprisingly close to that of the modern ‘Big Bang’. In Genesis, the creation of the world begins when God separates the light from the darkness. Grosseteste believed that God had created the world beginning with a tiny point of light, which exploded outwards. Its expansion created ‘extension’, or space, and the material from which God subsequently created the material universe over the next five days.

A.C. Crombie, in his Science in the Middle Ages, Vol. 1: Augustine to Galileo (London: Mercury Books 1952) writes

The first important medieval writer to take up the study of optics was Grosseteste, and he set the direction for future developments. Grossetest gave particular importance to the study of optics because of his belief that light was the first ‘corporeal form’ of material things and was not only responsible for their dimensions in space but also was the first principle of motion and efficient causation. According to Grosseteste, all changes in the universe could be attributed ultimately to the activity of this fundamental corporeal form, and the action at a distance of one thing on another was brought about by the propagation of rays of force or, as he called it, the ‘multiplication of species’ or ‘virtue’. By this he meant the transmission of any form of efficient causality through a medium, the influence emanating from the source of the causality corresponding to a quality of the source, as, for instance, light emanated from a luminous body as a ‘species’ which multiplied itself from point to point through the medium in a movement that went in straight lines. All forms of efficient causality, as for instance, heat, astrological influence and mechanical action, Grosseteste held to be due to this propagation of ‘species’, though the most convenient form in which to study it5 was through visible light. (99-100).

This makes it sound very close to the modern theory that all the forces – gravity, electromagnetism and the strong and weak nuclear forces – were united at the Big Bang, and subsequently separated out from this primal Superforce.

Grosseteste was also one of the medieval writers, who first posited the Moon as the causes of the tides. The association between the Moon and the tides had first been made by the Stoic philosopher, Posidonius, who was born c. 135 BC. Crombie writes

Grossetest in the next century [following Giraldus Cambrensus in the 12th] attributed the tides to attraction by the moon’s ‘virtue’, which went in straight lines with its light. He said that the ebb and flow of the tides was caused by the moon drawing up from the sea floor mist, which pushed up the water when the moon was rising and was not yet strong enough to pull the mist through the water. When the moon had reached its highest point the mist was pulled through and the tide fell. The second, smaller monthly tide he attributed to lunar rays reflected from the crystalline sphere back to the opposite side of the earth, these being weaker than the direct rays. (126-7). It’s not quite right. The tides are simply caused by the Moon’s gravity acting on the oceans as a whole. Mist isn’t involved. Nevertheless, he was right in pointing to the Moon as the cause of the tides.

Which is more than can be said of Bill O’Reilly. Until recently, O’Reilly was the lead anchor on Fox News, Rupert Murdoch’s right-wing news network over in America. The host of the ‘O’Reilly Factor’, he specialised in right-wing harangues which occasionally ended with him insulting and screaming at his guests if they dared to disagree with him. He did this to the son of one of the firefighters, who lost his life in 9/11. The lad committed the unpardonable offence of saying that his father would not have blamed all Muslims for the attack, and would not have wanted America to go to war over it. This was too much for the veteran newsman, who screamed at the lad that he was a disgrace to his father, and then had him thrown off the show.

He also showed himself massively ignorant scientifically in an interview with the head of American Atheists, the atheist movement, which I think was set up and headed for years by Madalain Murray O’Hair. Trying to refute whatever point the man was making, O’Reilly seized on the notion of the tides as something that was scientifically inexplicable. There are clips on Kyle Kulinski’s Secular Talk and other left-wing news programmes of O’Reilly repeating, ‘Tides go in, tides go out, you can’t explain it’. All the while the lad looks at O’Reilly with a bemused expression on his face, and simply comments, ‘Perhaps its the mighty Thor’. O’Reilly, however, didn’t get the hint that he was being justifiably mocked, and so simply carried on with his daft refrain.

O’Reilly’s comments and use of the tides shows that O’Reilly knew precious little science, and that Grosseteste had a better idea of what caused it 900 or so years ago, in an age when books had to be copied out by hand and western science was beginning the recovery of ancient Greek and Latin scientific and mathematical texts and learning from the great natural scientists and mathematicians of the Muslim world.

Given O’Reilly’s massive ignorance on something I can remember being discussed in some of the text books we had at school, it’s no wonder that American scientists, educationalists and the general public are seriously worried by Trump’s attack on science education in America, and particular in his attempts to cover up climate change.

As for O’Reilly, he was sacked from Fox News a few months ago after his sordid and vile attitude towards women finally caught up with him. Like the head of the network, Roger Ailes, O’Reilly used his position to try to exploit women sexually. In the early part of this century he was forced to settle a case brought against him by a female colleague to whom O’Reilly had made an uninvited and very unwelcome sexually explicit phone call. This was followed by a series of allegations by other female journalists at Fox News of sexual harassment. This got to the point where the advertisers on the network got fed up, and started taking their custom elsewhere, at which point the veteran reporter lost his job.

Bishop Grosseteste, however, remains one of great figures in the history of western science. While many scientists would not share his religious beliefs, and would question the grounding of his scientific views in them, he is nevertheless important as one of the leading medieval scientists, who contributed to the foundation of modern science through his study of optics, mathematics and the natural world.

The Saturn Five Variants that Were Never Built

May 4, 2017

And now a little break from the elections. This is a short video from Vintage Space, discussing the variants of the Saturn V moon rockets that were designed, but never built. These new space vehicles were designed to be bigger and better. From what is said about them in the video, it seems the designers adopted a modular approach, or something like it, so that stages and rocket motors could be swapped around and altered to allow the rockets to be customised to suit different missions.

It’s a pity that these awesome machines were scrapped at the end of the Apollo missions. I’ve read letters in Spaceflight, one of the magazines published by the British Interplanetary Society by scientists, who believed that the proper way into space would have been through building Big Dumb Boosters. Although not reusable, they could be mass produced, which would mean they could be constructed for the cost of a battle ship, and bring launch costs down to about $100,000.

Some space scientists are still bitter about the destruction of the Saturn Vs and even the plans for them. They were the only rockets capable of taking people out to the Moon, and potentially further out into the Deep Black. John Lewis in his book, Mining the Sky, on how humanity could expand into space to exploit the rich material and energy resources of the solar system, compares the destruction of the Saturn V to the destruction of Chung He’s fleet. Chung He was a Fifteenth century Chinese explorer, who led an expedition that sailed around the world. One of the places he reached was the Bight of Benin in West Africa. On his return, however, the eunuchs of the imperial court decided that the fleet represented a threat to the stability and order of the Chinese empire. So they destroyed it, thus helping to keep China isolated from the outside world for centuries. The bureaucrats, who ordered the destruction of the Saturn V moon rockets were, in Lewis’ view, guilty of the same kind of thinking.

There are alternative crewed space vehicles under development, and it is believed that the Chinese are planning to send a crewed mission to the Moon, quite apart from the various schemes to land people on Mars.

In the meantime, this video shows some the spacecraft that could have been.

TTA Spacecraft 2000 – 2100: Videos, Spacecraft and Book Cover Art

April 19, 2017

I put up a post at the weekend about a video I’d found on YouTube, in which a fan of Stewart Cowley’s Spacecraft 2000-2100 had made a short CGI film as a tribute. The film was a promotional video for the book’s fictional Terran Trade Authority, the global governmental organisation that had overseen the construction of the spacecraft which had taken humanity to the planets, and from then on to the nearest stars, meeting friendly creatures from Alpha Centauri, and fighting a war against aliens from Proxima Centauri.

The book Spacecraft 2000-2100 was a ‘future history’, of the type that was quite common in SF from the 1950s to the 1970s, when scientists and science fiction writers were confident that it would only be a matter of decades, perhaps only a few years even, before humanity established colonies in space – orbital cities, bases and then colonies on the Moon and Mars. FTL – Faster Than Light travel would be invented, and humanity would go on into the Galaxy ‘to seek out new life forms and new civilisations’, in the words of the Classic Trek.

The spacecraft in the book all came from SF book covers by some of the great space artists of the ’70s – Chris Foss, Angus McKie, Peter Elson, Bob Layzell, Fred Gambino and Jim Burns, around which the author, Stewart Cowley, wove his story of invention and exploration. It’s one of my favourite space books. The spacecraft depicted and their settings had a strange, otherworldly, literally alien beauty, even when the scenes were of industry or simple rocket launches. After I found the first video, I found another. This one is rather more complete. It uses the same computer techniques to recreate the spacecraft, as well as a whole scenes from the book. The spacecraft race across alien landscapes, rise into the air, hover above vast future cities, or prepare to dock with huge space stations.

I also found this video by Scott Manley on YouTube, where he talks about the book. He found it amongst his father’s old things, which rather dates me. Along with some of the other facts he mentions, he talks about the picture of an alien spaceship, which was plagiarised a few years ago by another artist, who entered his version for the Turner Prize. Apparently, the book was also republished in 2005, but was not well-received. The future history had to be rewritten, and some of the pictures were replaced by computer art. There has, however, also been a Role-Playing Game created, which is set in the same universe as the book.

Here’s a few of the book covers, from which the art was taken. Top far left is by Angus McKie; top let is Tony Roberts, bottom left is Bob Layzell, while bottom right is by Peter Elson. Neither of the two bottom images appear in the book. Other pieces by them do appear, and these show Layzell’s and Elson’s style
This and other great pieces of SF art can be found in the book Sci-Fi Art: A Graphic History by Steve Holland (New York: HarperCollins 2009).

Soviet Space Art and Music

April 19, 2017

This is another fascinating space video I found on YouTube. Russia had a very strong space culture, possibly because it was the one area where they were undoubtedly in front of the Americans and the rest of the world for so long, arguably right up to the Moon landings. At one point there was a regular spot on Soviet television, where schoolchildren spoke to the cosmonauts on board the Salyut space stations.

The paintings in the video come from a magazine called Tekhnika-Molodezhi, which I think translates into English as ‘Technical Youth’. It shows how the Soviets imagined a future in which the Soviet Union, and by implication, the rest of the Communist bloc, were conquering space, landing on the Moon and colonising Mars. Back on Earth, they were pioneering new forms of transport technology, including giant walking robots, trains powered by magnetic levitation and futuristic cars. Many of these illustrations seem to have come from the 1950s. This was an optimistic decade for the Soviet Union. Stalin was dead, and Khrushchev had pledged himself to destroying the old b*stard’s ‘cult of personality’ in his 1953 Secret Speech. Living standards were rising, and consumer products were being developed and becoming more widespread. Something like an ‘affluent society’ was developing in the Soviet Union. At one point it looked like the Soviet Union was going to realise its potential and overtake the West as the most developed, progressive economy, a prospect that terrified the Americans. For more information on this, see the book Red Plenty.

The music’s electronica from 1984, according to the website. It’s interesting looking through some of the videos on the site, which also show that Russia produced some very interesting electronic/ synthesizer ‘pop’ music. The impression we always had when I was at school was that in popular music, the Russians were way behind us in the West. It’s fair to say that the Soviet authorities did distrust ‘decadent’ western music – Boney M’s ‘Ra-Ra Rasputin’ was banned because it was all about the Mad Monk, who was a non-person to the Soviet censor and official history. But it also shows that there was also a thriving youth musical culture as well, something I only found about at College.

Animated Video Based on Terran Trade Authority Spacecraft

April 14, 2017

Looking through YouTube, I found that someone had made an animated video about the spacecraft depicted in Steward Cowley’s Spacecraft: 2000 to 2100 (London: Hamlyn 1978).

The book’s supposed to be a handbook of 21st century spacecraft, published by the Terran Trade Authority. In fact, it’s a collection of illustrations from SF book covers by the great space artists Angus McKie, Bob Layzell, Tony Roberts and others, which Cowley then described as real spacecraft. These were part of a ‘future history’ of human space exploration and colonisation which included humans travelling to encounter intelligent alien civilisations on Proxima and Alpha Centauri, and fighting a war with the Proximans. As well as Spacecraft 2000-2100, Cowley also wrote Great Space Battles, the Tourist’s Guide to Transylvania, based on Horror book covers, and Home Brain Surgery and Other Household Skills. The artwork is stunningly beautiful. Here are a few examples.

As with so many books on space written in the 1970s, it had a timeline of what we could expect in the coming decades, predictions which now seem hopelessly dated and optimistic. For example, the ‘key historical dates’ in Spacecraft: 2000 to 2100 are

Arthur C. Clarke Book on the Terraforming of Mars

March 18, 2017

Arthur C. Clarke – The Snows of Olympus: A Garden on Mars – The Illustrated History of Man’s Colonization of Mars (London: Victor Gollancz 1994).

A little while ago I put up a number of articles on the possible terraforming of various planets in our solar system. The prime candidate at the moment would be Mars, but people have also suggested ways to terraform Venus and the Moon. I’ve managed to dig out from my bookshelves a copy of Arthur C. Clarke’s book, The Snows of Olympus, which I bought way back in the 1990s. Clarke’s been called ‘The Space Prophet’ because of his article published in a radio hobbyists’ magazine shortly after the War predicting geostationary communications satellites. He has jokingly said in an article ‘How I Lost a Million Dollars in My Spare Time’ that he should have patented the concept, and so made himself a billionaire because of its immense value to the telecommunications industry. This book is no less prophetic in that it uses computer simulations to depict the gradual greening of the Red Planet over a thousand year period from the next few centuries to c. 3000.

The book has a prologue, in which Clarke gives the text of a speech he gave to future Martian colonists as part of the Planetary Society’s ‘Visions of Mars Project’. Launched by the late and much-missed astronomer and space visionary, Carl Sagan, this was a project to send the future colonists the gift of a collection of SF short stories about Mars aboard two probes due to land there. There’s then a short introduction in which Clarke lays out the aims of the book. The first chapter, ‘Prelude to Mars’, discusses the history of the exploration of the Red Planet by terrestrial astronomers and writers, such as Giovanni Schiaparelli, Percival Lowell, H.G. Wells and Edgar Rice Burroughs, C.S. Lewis in Out of the Silent Planet, and the controversy surrounding the supposed ‘face’ on Mars, made by Richard Hoagland and others.

Chapter 2 – ‘The Curtain Rises’ – is on the probes sent to explore Mars, such as the Mariner probes and discussion between himself, Sagan, Ray Bradbury and the JPL’s Bruce Murray at the Jet Propulsion Laboratory on the probes and their findings. He goes on to discuss Viking probes and the debate about American and Russian cooperative ventures in space research. This last ended for a time because of international tensions created by the Solidarity crisis in Poland.

Chapter 3 – ‘Going There’, describes the problems and suggested methods for reaching Mars, establishing crewed bases there, including various types of rocket from the conventional chemical to nuclear-thermal and atomic; solar sails and space elevators, George Bush seniors’ intention to launch a crewed mission to Mars by 2019, and the tasks that would immediately face the astronauts landing there.

Chapter 4- ‘Virtual Explorations’ is on the use of computers and VR to explore and map Mars, and particularly the Vistapro programme used in the generation of many of the images in the book.

Chapter 5 is on the artistic and computer depictions of Olympus Mons, the planet’s highest mountain and the gradual reclamation of its surface by vegetation, beginning with lichens, during the long centuries of terraforming. This culminates in the emergence of liquid water and creation of a sea surrounding the mountain.

Chapter 6 does the same for Eos Chasma, the ‘Chasm of the Dawn’, in the Valles Marineris.

Chapter 7 shows the same process as it would affect the Noctes Labyrinthes – the Labyrinth of Night. This forecasts the growth of forests in this part of Mars, beginning with pines but later including deciduous trees.

Chapter 8 – ‘The Longest Spring’ discusses the various methods that could be used to terraform Mars, such as coating the ice caps with carbon from Mars’ moon, Phobos, the use of orbiting mirrors to melt them, raising its temperature by turning Phobos into a miniature sun for about 40 days using ‘muon resonance’ – a form of nuclear reaction, and bombarding the planet with comets to cover it with water, and ‘Von Neumann’ machines that would gradually terraform the planet automatically.

‘Disneymars’ looks forward to a museum display and audiovisual presentation that would show the colonists what their planet would look like in the future as the terraforming progresses.

Chapter 9 – ‘Concerning Ends and Means’ discusses the moral dimension of terraforming, the immense historical importance of exploration and the need to continue this exploration to the Red Planet in order to preserve human civilisation and progress.

There are two appendices. The first is an extract from a speech, The Mars Project: Journeys beyond the Cold War, by US senator and WWII hero, Spark Matsunaga. The second, ‘So You’re Going to Mars’, is fictional advice given by the immigration authorities to people moving from Earth to Mars.

The quality of the computer graphics is mixed. Many of them, which were without doubt absolutely astonishing for the time, now look rather crude and dated as the technology has improved. Others, however, still stand up very well even today. The quality of the computer simulations of the terraforming process can be seen from this image below of what Eos Chasma might look like in 2500 AD.

There are also plenty of illustrations of Mars, rendered using more traditional artistic methods such as painting, including photos of Percival Lowell’s own drawings of what he believed was the planet’s network of canals.

Although the computer tools may have been superseded and improved in the decades since the book’s publication, I think the science, and the social issues Clarke discusses, are still solidly relevant and contemporary. Certainly there is now a popular movement to send humans to the Red Planet at some point in the coming decades, and prospective future colonists have even come forward to volunteer a few years ago. There is, however, a greater awareness of the medical dangers from radiation and microgravity that would affect – and possibly destroy – a mission to Mars. The dream, however, is still there, as shown by the success of the film The Martian a few years ago.

7 Earthlike Worlds Discovered Around Star Trappist-1

February 25, 2017

More awesome space news! This week, NASA announced that their Spitzer telescope had discovered a system of seven worlds orbiting the ultra-cool red dwarf star, Trappist-1. The star takes its name from the Belgian operated observatory, which found it. Astronomers from Liege university discovered two of these worlds. Three of these rocky worlds lie in the planet’s habitable zone, which means they could have life, and all of them have temperatures which would permit liquid water to exist. Because of the star’s small size and extremely cool temperature, they are closer to their star than Mercury is to the Sun. This video from the Kepler Telescope Channel also looks forward to the development of spacecraft that will be able to reach something like lightspeed, so that humanity may at some point in the future be able to expand into space. And at just 39 light years away, Trappist-1 and its worlds are a suitable nearby target for exploration. The scientists, who made the discovery, also say that the planets are so close together, that you’d be able to see all of them from the surface of one of the planets. They would loom larger than Earth’s Moon, and it would be possible to see even clouds and geological features on their surface.
