Discussion Overview

The discussion centers around C.S. Lewis's portrayal of gravity in his science fiction work, particularly in "Out of the Silent Planet." Participants explore the accuracy of his representation of gravitational forces in space travel and the implications of bending scientific rules for storytelling purposes.

Discussion Character

  • Debate/contested
  • Conceptual clarification
  • Exploratory
  • Meta-discussion

Main Points Raised

  • Some participants argue that C.S. Lewis misunderstood gravity, suggesting that he believed astronauts would feel less gravitational force as they approached the Moon.
  • Others point out that Lewis's works are more religious allegories than true science fiction, indicating a lack of concern for scientific accuracy.
  • A participant recalls their experience studying various sci-fi authors, noting that character development often suffers in favor of scientific accuracy.
  • There is a mention of Jules Verne's inaccuracies regarding gravity in his work "De la terre à la lune."
  • One participant questions whether it is possible for a spaceship on a straight path to experience different gravitational effects, prompting a counterargument about the complexities involved in such a scenario.
  • Another participant reflects on their enjoyment of Lewis's atmospheric descriptions in "Out of the Silent Planet," despite questioning his understanding of gravity.
  • Some participants assert that superficial knowledge should not disqualify someone from writing fiction about scientific topics.

Areas of Agreement / Disagreement

Participants express multiple competing views regarding C.S. Lewis's understanding of gravity and the nature of his writing. There is no consensus on whether his portrayal of gravity is acceptable within the context of fiction or if it undermines the scientific basis of his stories.

Contextual Notes

Participants highlight the tension between narrative creativity and scientific accuracy, with some expressing frustration over the blending of the two in Lewis's works. The discussion also touches on the broader implications of how science fiction can be influenced by the author's understanding of science.

CS Lewis didn't really get the gravity thing. In a spaceship the astronauts are attracted to the center of the ship, enough so that they seem to have fairly normal gravity. When they get close to a planet this is screwed up and they have a hard time keeping their balance.

The hero at first mistakes the Earth for the Moon. He can tell they are different though because the Earth is larger.

Can you give us some context here?

What book or story of CS Lewis had this gravity confusion thing?

Out of the Silent Planet
 
Okay, I haven't read that book.

This is not uncommon where the rules of reality are bent to make better stories.

In college, we studied several great sci-fi authors with the two profs one an English Lit ripping the poor character development and the other a Physicist ripping the science got me so depressed I couldn't read another sci-fi novel for at least ten years.

Some of the authors we discussed were Larry Niven's Ringworld and Heinlein's Starship Trooper stories. Niven's story scored well in the science aspect but still had some problems.

I remember folks wondering about how a Ringworld could be built and how stable it would be. Larry Niven to his credit, factored the criticism into his future novels.
 
How Starship Trooper ruined science?
ON: that Gravity seems lame to me...
 
Many of the stories were ripped apart due to character development. So many characters were simply names on cardboard in a beautiful or not so beautiful alien landscape.
 
This was not simply a situation "where the rules of reality are bent to make better stories." C.S. Lewis really believed that, as the rocket ship moved toward the moon, the people would feel less and less "gravitational" force toward the Earth until they reached the point where the gravity of the Earth and moon "balanced", then would be attracted toward the part of the rocket ship closer to the moon.

Of Course, "Out of the Silent Planet", "Perelandra", and "That Hideous Strength" were really "science fiction" books. They were, rather, Christian allegories. C.S. Lewis did not know much physics and was not really concerned about scientific accuracy.
 
Jules Verne got it wrong too in De la terre à la lune.

Isnt it possible, if the ship is going on a straight line instead of an orbital path?

No, it is not! In order to get the ship to go in a straight path, given the gravitational pulls of the Earth and moon, you would have to have some very complicated accelerations that would cause some very complicated "pseudo gravitational" effects in the ship.

Having just stumbled into this thread, I've not yet blown the dust off my fragile paperback edition of 'The Silent Planet'. But I do well recall my puzzlement from long ago concerning the gravity issue. Was CS Lewis aware of his lack of understanding about gravity, I wonder? Or did he consider it a non-issue in the first place? On the other hand I remember enjoying the way he handled the atmosphere of Mars and how its varying density affected the various Martian species - I can't at present recall their names. It may not have been accurate, but it certainly left a vivid impression upon me at the time.

C. S. Lewis did NOT write "science fiction". He wrote religious allegory sometimes clothed in a science fiction robe. He really did not know enough science to write science fiction.

Since when is more than superficial knowledge of any subject a requirement to write fiction about it?
