+This is Hacker Public Radio episode 4,480 for Friday 3 October 2025.
+Today's show is entitled, Arthur C. Clark becomes successful.
+It is part of the series science fiction and fantasy.
+It is hosted by Ahouka and is about 14 minutes long.
+It carries a clean flag.
+The summary is, a look at Arthur C.
+Clark's rise to science fiction prominence.
+Hello, this is Ahouka for Hacker Public Radio.
+Welcoming you to another exciting episode in our ongoing series on science fiction and
+fantasy.
+And I'm continuing our look at Arthur C. Clark and how he became the prominent successful
+science fiction author that he's known as today.
+Because while the earlier works that we talked about previously against the fall of
+night and the city and the stars have gathered something of a reputation, you know, I think
+if he'd stopped there, he would have gined just a footnote at best.
+It was the third novel, Childhood's End, which was published in 1953.
+That really rocketed him to the top.
+Now it is based on a short story he wrote in 1950 called Guardian Angel.
+Then in 1952 he started working on expanding it into a full novel.
+In the latter part of the 20th century, as this novel takes place, the US and the Soviets
+are engaged in a space race.
+Now remember, he was doing all of this before Sputnik.
+So it was speculative, and he has it towards the end of the 20th century.
+It happened faster than he anticipated, I think.
+Well, all of a sudden alien spaceships arrive and station themselves above Earth's major
+cities.
+They announced that they are taking control over all international relations in order to
+prevent the extinction of the human race.
+This was at the height of the Cold War when nuclear annihilation seemed imminent and was
+right around the same time that Asimov was writing novels where the surface of the Earth was
+largely radioactive.
+So it was in the air at the time.
+These aliens became known as the overlords, and in time people become used to them.
+But they never show themselves.
+They say they will when the time is right, some time in the future.
+This does make some people suspicious of their intentions, though.
+But the overlords are clearly more technologically advanced than the humans, so there really isn't
+anything the humans can do.
+Now the overlords show a particular interest in psychic research, though they are interested
+in learning everything about humanity.
+By eliminating war, the overlords have created an age of prosperity for the whole planet,
+and people start to relax and enjoy its benefits.
+The curiosity still exists in humanity, and some people figure out the home planet of
+the overlords, and one man stows away on a supply ship heading back to their planet.
+Now finally, the overlords do reveal themselves, and they reason they hid this for so long
+becomes apparent.
+Their appearance resembles the classic pictures of demons in Christian mythology, with
+cloven hooves, leathery wings, horns, and barbed tails.
+But they waited long enough that this does not cause an uproar now because we are in
+a golden age of prosperity.
+Now about a century after the overlords' first appearance, human children begin to display
+mental powers, such as clairvoyance and telekinesis.
+And the overlords finally reveal their true purpose.
+They serve something called the overmind, a vast galactic intelligence.
+Their role is to serve as a bridge, to other species, to help them develop to the point
+of eventual union with the overmind.
+But the overlords themselves will never be able to join, that is their sad fate.
+Meanwhile, the time when humans were individuals is coming to an end.
+The children of humanity are already starting to merge into a collective consciousness.
+For their safety, they are moved to a continent of their own, segregated from the rest of humanity.
+But the parents left behind start to die off, many of them commit suicide, and no more
+children are being born.
+Now the overlords are still watching and monitoring.
+And as this happens, that stole away returns, he is now the last human on earth.
+And when the merged children start manipulating the moon and the planets, the overlords decide
+it is too dangerous to stay, and they are getting ready to leave.
+They offer to take the stole away with them, but he refuses and stays to report to the end.
+This is still considered a classic, and it was nominated for a retro Hugo for Best
+Novel in 2004, though it lost to Ray Bradbury's Fahrenheit 451.
+Well, it was in good company, because it also nominated that same year with Asimov's
+Caves of Steel.
+So that is the brakes, you know, you are up against some other really good novels, and
+Fahrenheit 451 is certainly a classic.
+Now Stanley Kubrick actually expressed interest in filming Childhood's End, but instead
+decided to go with 2001 Space Odyssey, we'll be getting to that shortly.
+Childhood's End also had an audio adaptation by the BBC.
+And that can be found at the Internet Archive.
+In fact, there's a lot of these BBC radio shows that you can find on the Internet Archive.
+So it's something to take a look at.
+And as I mentioned before, I think the Internet Archive is also deserving of support.
+In 2015, the sci-fi channel did a three-part ministeries adaptation of Childhood's End, which
+can be purchased as a DVD.
+I've put links to the DVD, the Internet Archive, etc. in the show notes, so you can access
+any of this if you are interested.
+Now this holds up much better as a novel than the City and the Stars.
+But while it's better novel, I again find little in it to support Clark's reputation
+as a writer of hard science fiction.
+Now I've enjoyed reading it several times.
+But while telepathy, group consciousness and the galactic overmind are clearly speculative,
+it is hard to claim that there is much science to it.
+The overlords clearly have advanced science and technology, but we never really see anything
+more than the effects of it.
+The science behind this technology has never brought up and is really not part of the
+plot to any degree.
+But the next story remedies this.
+And that story is called a Fall of Moon Dust, published in 1961.
+Now Clark published other stuff between those two, but we're just trying to look at the
+highlights of this.
+One of the dangers in writing hard science fiction is opposed to fantasy is that the facts
+can change as new science comes in.
+For instance, when Giovanni Shaparelli described what he called the Canali of Mars in 1877, he
+used a word which meant channels in Italian, but which later got translated as canals.
+And those are two very different things.
+You know, a channel is a natural formation.
+A canal is something that has been built by somebody.
+And well into the 20th century, these canals were seen by astronomers.
+And since they were obviously built by somebody that meant there had to be inhabitants of
+Mars who constructed them.
+So HG Wells could use these inhabitants as characters in his The War of the Worlds, 1897.
+But like canals, science fiction writers developed a whole mythology about this.
+The canals were clearly built to transport water.
+They could see the polar ice caps expanding contract seasonally.
+So the canals must have been to carry water from the poles to the inhabited areas.
+Of course, now we know that the polar ice caps were real, are really made of carbon dioxide
+that freezes out of the atmosphere and then sublimates back into the atmosphere seasonally.
+Now in Well's story, Mars was starting to dry out.
+And that's why they invaded Earth.
+And I'll mention how all those stories look after we have been to Mars, robotically at this
+point, but we've been there, and discovered that there never were any canals.
+It was all an optical illusion caused by the human brain's tendency to look for patterns
+in random data.
+And there are no Martians.
+Similarly, Venus was covered in clouds, so writers imagined a planet that was swampy
+and humid, thus causing the clouds.
+And thus it would be filled with inhabitants adapted to swamp conditions.
+Now we know that Venus' clouds are made of sulfuric acid, and the surface temperature
+is 464 degrees centigrade.
+Well, let me bring this up.
+At one time there was a theory that large parts of the Moon's surface were covered in
+deep layers of dust.
+We know now that that's not the case.
+There is a layer of dust, it's not particularly deep, and every land or spacecraft to touch
+down is landed on a solid surface.
+But Clark, like many science fiction writers, went with what was clearly a possibility
+at that time, and extrapolated from it, you know, what if the Moon was covered in deep
+layer of dust?
+So he's let down a little by the advance of knowledge, but you got to get him a pass.
+He didn't know what we now know, and his extrapolations were legitimate given the then
+state of knowledge.
+So in this story, the Moon has been inhabited at this time by scientific missions for a while,
+and now tourists have started to come.
+One company offers a tour of a lake full of dust on which a boat floats.
+The dust is so fine, it behaves like water, so this is working, it's possible.
+Then the disaster strikes, a cave in below the boat causes it to sink into the dust, and
+now it is a race against time to find a way out.
+In the boat, they are mostly waiting to be rescued, they are in a sealed vessel, and
+are fine for the moment, but problems are looming.
+The dust is a very efficient insulator, and the heat starts to build up.
+Air supply is limited.
+Communications are impossible, so they have no way of communicating.
+On the outside people know the ship has been lost, but they don't know exactly where
+it is.
+They might have to abandon the search.
+But then an astronomer in a satellite above the Moon says he has found a heat signature.
+Well, they send out a rescue vessel and are able to make contact, but time is running
+out.
+They do finally succeed in running a pipe into the ship to deliver oxygen, but the heat
+build up is still going on.
+They know they have to get the people out, and hit on a plan to drop a case on onto the
+buried ship with the tube running back to the rescue vessel, so the people can climb
+out.
+But then the sunken ship lurches into an angle instead of being level.
+They have to try a different approach.
+But another problem arises when the holes they have cut are leaking in dust, which gets
+into the batteries and shorts them out.
+This starts a slow burn that will ultimately create an explosion.
+Now in the end everyone is saved, but the suspense is maintained throughout.
+This is a really enjoyable story that keeps you on the edge of your seat all the way through.
+And this is exactly the kind of story people mean when they talk about hard science
+section.
+The problems they face are perfectly reasonable from a scientific and engineering perspective.
+And they are solved one by one through the application of science and engineering.
+There is no use the force luke going on here, no made up imaginary future science.
+The fiction, once you give Clark a pass on the idea of deep moon dust, is entirely the
+location.
+It is happening on the moon.
+Now this story was adapted for radio by the BBC in 1981.
+It is available for purchase.
+It was released as a CD audio, but it is out of print.
+So you'd have to look for it.
+But it is also available again at the internet archive.
+And I've put a link to that in the show notes.
+So you can get the audio adaptation if you want.
+And so this is a hook up for hacker public radio signing off and is always encouraging you
+to support free software.
+Bye bye.
