This question is inspired by the movie Interstellar but asks a basic question about relativity. Everyone talks about gravitational time dilation but I am wondering if gravity has an effect on space as well, after all it bends space time. I have not found a lot of information on length contraction in the context of gravity (velocity, yes, but not gravity). If we were to look at a clock on a planet with a very strong gravity, we would see time move extremely slow but would we also see the clock stretched/contracted? Also, would light "appear" to travel faster/slower on this planet when externally observed?
