In “It,
the Terror from Beyond Space” (s. Jerome Bixby), early on in the movie a
crewmember is cheerfully pouring steaming hot coffee into the coffee cups of
the crew on a sleek cylindrical spaceship which has several ‘decks’ and there
is no explanation of how gravity is explained in any way.
But maybe that is good because in a lot of these old movies they make it
a science lesson with every move they make (in ”Destination Moon”
there is a Woody Woodpecker cartoon shown to prospective big wheeler-dealers to
explain how rocket propulsion works), explaining why they do this or do that,
usually to some guy from Brooklyn in the crew that keeps mentioning the
Brooklyn Dodgers..
Many SF movies do the same thing: “Forbidden Planet,” the redoubtable “Angry
Red Planet,” “Rocketship X-M,” the Flash Gordon serials, Star Trek, Lost
in Space, almost any SF movie or TV show, and Star Wars.
In Heinlein’s “Destination Moon” and others, like “Flight to Mars they explain
about why one has to be strapped in so as ‘not to float’ on the nuclear-powered
ship run on steam thrust.
Also done in the Willy Ley inspired ”Conquest of Space” (p. George
Pal) but the movie goes as step further as the Earth-orbiting space station
revolves and spins to create artificial gravity.
It was not until “2001: A Space Odyssey” that there was an actual rotating
living quarters on a ship that generated some centrifugal force to create
artificial gravity, and again in the sequel, “2010.”
Even in “Alien” there is no explanation for the induced gravity in the ship. In
the Star Trek movies they finally explained it all with convenient Anti-Gravity
devices.In H.G. Wells “The First Men in the Moon” there is a “Cavorite”
substance which works the same way. .
In many spaceships in older movies there is no space below to account for the
mechanics that make the ship run. If you ever look at a V-2 rocket diagram
you’ll see Werner Von Braun’s genius apparatus that made it go. Look what it
took for the Apollo missions.
In very ‘cheap’ movies you’ll see the gangplank to get into the ship is at the
very bottom of the ship. In Jules Verne’s “From the Earth to the Moon” the ship
is just a large bullet but we realize that shooting a large manned projectile
is essentially “Spam in a Can” to anyone within the projectile..
In James Blish’s novels he came up with this: SpinDizzy: A
device that made use of a relationship between electron spin, electromagnetism
and gravity allowed any object to leave the Earth’s surface. ;.Famed Astounding
Editor John W. Campbell, Jr was big on the Dean Drive, which did not work. He
was obviously a legend as an SF editor. He often talked about Scientology and
Psionics as well. The Dean Drive:
The Dean drive was a device created and
promoted by inventor Norman Lomer Dean (1902–1972) that he claimed to be
a reactionless drive.[1] Dean
claimed that his device was able to generate a uni-directional force in free space, in violation of Newton's third law of motionfrom classical physics. His claims generated notoriety
because, if true, such a device would have had enormous applications,
completely changing human transport, engineering, space travel and more.[2] Dean
made several controlled private demonstrations of a number of different
devices, however no working models were ever demonstrated publicly or subjected
to independent analysis and Dean never presented any rigorous theoretical basis
for their operation. Analysts conclude that the motion seen in Dean's device
demonstrations was likely reliant on unsymmetrical frictional resistance
between the device and the surface on which the device was set, resulting in
the device moving in one direction when in operation, driven by the vibrations
of the apparatus
Woodward effect. A reactionless thruster would have many practical
applications, including the propulsion of spacecraft. According to Dean, his
drive is a reactionless thruster, and his models were able to demonstrate this
effect. He received two patents for related devices that are known to be unable
to generate a uni-directional force, but he occasionally demonstrated devices
that were different. Dean’s claims of reactionless thrust generation have
subsequently been shown to be in error; the thrust generated is understood to
be reliant on friction with the surface on which the device is resting. .
Sidenote: I read that Phil Dick sent him a lot of stories but that Campbell
thought that PKD was ‘insane,’ just plain crazy. That is, his stories were so
far-fetched that he did not understand them. So he never bought anything by
PKD. .
I wrote a short story about twenty years ago called ”Jimbob Goes to
Mars” which essentially took from Steinbeck’s ”The Grapes of
Wrath” about how one of the Joad boys had ‘a certain way of knowin’ about
engines and trucks and could just fix ‘em’. I just applied that to
rockets and had pimple-faced Jim-bob Johnson offworld on Io applying the
courses of a Dr. Biddle, etc. .
I’ve also left out here 99 percent of what is left to talk about propulsion in
literature or reality, star drives or ion drives or fusion drives. When I was a
kid in all our Encyclopedias they had diagrams of potential moon shots and
potential Mars shots and how we would get there. I never did outgrow the
sense of wonder about the way we could get to a destination in space. I
remember reading books on how to build a Moonbase, whether to dig out a vast pit
on the surface and cover it, hence the base is completed.
When I was a kid I realized while watching enough space launches that certain
things in science fiction movies were taken for granted and there is not much
verisimitude. I just know that Nasa astronauts don’t talk much about the
Brooklyn Dodgers while inflight.
