This is not 'Hard SF'. This is science fantasy. Comic book SF. I'm really happy to learn this now.
Because otherwise it would gone to see the movie and that would be bad. Because once, in a theater watching 'Mission to Mars', I literally stood up and screamed, "That's not how orbital physics works!" during the 'conga-line-in-space' scene.
Yes, I really did that. It was embarrassing.
