I was just wondering, what exactly is movement?  Like if we are all part of space, then what exactly is our movement within space? We can't move relative to space obviously, but what exactly is happening to space as we move?  Wow this is hard to explain. I have this weird incomplete picture in my head of space like a thick web of strings and when we move its like the mass of strings moves with us but pulls and sways on other masses of strings from other objects. Why strings instead of water I do
