Missions of Antigravity

I was tempted to call this blog post "Probability Zero". In 1942, Asimov published one of the first stories in the Probability Zero series: "Time Pussy", a silly story about animals with temporally-warped physiology. Much later, in 1987, Asimov published "Left to Right", which I read in Gold. "Left to Right" takes as its starting point the physicist Robert L. Forward. In this nerd joke story, Forward is transformed into Robert L. Backward during a physics experiment. Forward dabbled in science fiction and wrote about topics such as antimatter and antigravity.

My first introduction to weird science fictional physics came in Asimov's novel The Gods Themselves. Asimov imagined an alternate universe where the laws of physics were different than what exists here in our universe. Asimov also made use of imaginary positronic brains for no better reason than to have a cool-sounding futuristic alternative to electronics.

Gravity Nullification
Gravity nullifying materials such as Cavorite have long been used in some science fiction stories. If you want your spacecraft to more easily blast into outer space, simply shield it from the Earth's gravitational field.

Antimatter-powered space travel and antigravity were integral to the imagined future of Star Trek. Could floating cities such as Laputa and Stratos use materials with negative mass in order to defy gravity?

I recently mentioned the story "Noise Level" by Raymond Jones which is not content to simply imagine a future with antigravity technology. In "Noise Level", readers are dropped into the middle of a research and development project aimed at developing the first practical antigravity device.

Sci Fi stories that tackle the details of fictional science risk alienating readers. I recently commented on "Do I Wake or Dream?", a story by Frank Herbert that has annoyed many readers with its jargon-filled handwave account of how to create a conscious computer.

What about "Noise Level"? How did readers react to the fictional R&D program described in that story? Lucky for us, we have quantitative data from the 1950s.

story popularity analytics
John Campbell printed reader rankings of the stories that were published in Astounding. At the end of 1952, Asimov was ranked number 1 for the first two parts of his story "The Currents of Space". However, in December, "Noise Level" was more popular than the final part of Asimov's story.

I get the feeling that given Campbell's background in physics, Astounding was something of a bastion of hard science fiction. Other Sci Fi magazines such as Galaxy moved in other directions and probably had a different kind of readership.

One Penny per Word
A details-oriented story such as "Noise Level" was popular with the science nerds who subscribed to Astounding while the technical details in "Do I wake of Dream?" only annoyed the readers of Galaxy. How could an editor like Campbell efficiently attract Sci Fi story writers who appealed to his readers? Beginning in April of 1953, Campbell began giving a monetary bonus to authors who were ranked as having the most popular story in each issue of Astounding.

In May of 1952, Thomas J. King and Robert Briggs published an article describing how to clone frogs by nuclear transplantation. The January 1953 issue of Astounding contained an article about human clones called "Un-Man". Sadly, "Un-Man" was written by Poul Anderson who had a background in physics, not biology.

Genes in 1953
In the text of "Un-Man", Anderson tells readers that "a gene is nothing but a set of giant protein molecules". In making this false claim, Anderson was probably under the influence of Alfred Mirsky, who erroneously believed that proteins, not DNA, made up the linear molecular filaments of chromosomes (for example, see THE COMPOSITION AND STRUCTURE OF ISOLATED CHROMOSOMES).

Mirsky wrote in 1951, "protein is itself a microscopic thread, whereas DNA is not, the protein seems to be the fundamental fiber of chromosomes". In 1953, Watson and Crick published their DNA double helix model which shows how a sequence of nucleotides might store genetic information in a long DNA polymer. Despite its bogus molecular biology, "Un-Man" was the most popular story in the January 1953 issue of Astounding.

Antigravity in 1966
In the 1970s, when I entered into my personal golden age of science fiction, I was discovering re-runs of Star Trek and I read Born Under Mars by John Brunner. When I found antigravity technology in stories such as "The Cloud Minders" and Born Under Mars I was not surprised. I always assumed that devices such as Nomad and M-4 were able to float because of antigravity technology. In Born Under Mars, Brunner was concerned about his imagined Martians, human beings who had lived on Mars for many generations. The Martians could not easily survive on worlds with strong gravitational fields, particularly if they did not have a nulgee bed to sleep in.

And of course, artificial gravity could be used to boost gravity, too. The main character in Born Under Mars frets about the inevitable coming time when gravity would be boosted inside Martian cities for the convenience of people from Earth who were used to higher gravity.

Born Under Mars is set perhaps 1,000 years in our future. There have been almost no significant technological developments since the time of Einstein beyond the "natural" developments of a faster-than-light spaceship drive and related technologies such as that for artificial gravity control. Brunner does adopt for his story the existence a torture device, a whip, that directly stimulates pain sensory neurons without leaving any residual tissue damage. Sadly, the interior art for Born Under Mars depicts the Hi Tek™ neuronic whip as being a conventional whip.

The main background premise in Born Under Mars is that humans have reached some natural limit for technological development. Further progress will only be possible by genetic selection for an improved type of human being with greater cognitive abilities.

How will this brain boost be achieved? Brunner imagined a secretive conspiracy that reminds me of Asimov's saga of the Foundations, where the Super Secret™ Second Foundation must guide galactic civilization towards a better future. In Bunner's imagined future, as Humanity spreads outward into the galaxy, half of the expanding human civilization (a faction known as the Centaurs) has a rigid social structure, including a planned breeding program. However, nobody likes the tight-assed Centaurs. The other half of the galaxy is populated by the easy-going Bears. The plan is for the Centaurs to evolve a new type of  superhuman by selective breeding, but then the new Super Genes™ will stolen and spread among the Bears.

Born Under Mars is a relatively short and fun mystery adventure. It reads like a story set in post WWII England with bumbling spies from America, Russia and China all trying to figure out what is going on while a Super Secret™ organization based in London on Mars is able to come out on top.

More Brunner
In the March 1953 issue of Astounding is Brunner's first story published in America, "Thou Good and Faithful", which is also a fun little story. It was the most popular story for readers of Astounding that month and also was the cover story for that issue.

"Thou Good and Faithful" has a great premise: that if we were to visit distant exoplanets, we should not be surprised to meet artificial lifeforms of alien design rather than biological creatures such as ourselves.

In Brunner's imagined future of "Thou Good and Faithful", humans from Earth are relentlessly spreading through the galaxy, ready to blast any native lifeforms that get in the way of their colonization efforts. It is a surprising revelation for the humans when they come across some aliens who offer to be friends.
