My current picture of how gravity works is this (its probably wrong because it doesnt work for light. I’d like a better explanation from you guys):
objects have to move in the speed of light in space time, so when they encounter a position in space in which time is slower (this is the result of gravity. and my point of misconception probably), they have to compensate with movement in space . but this doesn’t make sense for light. it travels in the speed of light in space always, and therefore does not advance in time (from its point of view). so there is no reason for light to change its course in space.
if this is wrong i would very much appreciate a better explanation?
