Last night I watched Moon and it struck me that the gravity seemed to change depending on Sam's location:
- On the Moon's surface, gravity seemed to be as expected, as evidenced by Sam's slow movement.
- Inside the base, the gravity was just like on Earth. Was there some kind of "gravity generation device" like most "soft" sci-fi, eg Star Trek?
- Most surprising, to me, was that the gravity even seemed Earth-like inside the lunar rovers! Was that just a production error?
I ask because I've read that Moon was intended to be hard sci-fi but this was (to me) an obvious failing.
Was this a production error or was there an in-universe explanation?
