Hmm.. Lets say we have two points, A and B. Both points are in a vacuum and the surroundings are irrelevant (ie not going to collapse). What separates point A from point B? I can't feel anything or see anything. But A obviously isn't B. And if there were any light, the same object at either point would appear different depending on where the observer stood. Or would it?
So no, I haven't answered my question.. I'm even more confused than I was when I asked it.
On a similar subject, do points in space move? Or does matter move about points? From what I understand, gravity is the bending of space around objects with much mass. But what is bent? Gravity obviously exists in a vacuum, so matter isn't what is bent. And you can't bend nothing. So you're apparently bending space, and the actual points that represent where objects are move. And in what way is space bent? I don't believe it goes left, or right, or up, or any of the basic three dimensions we can observe. Does it bend time-space, just the time aspect? In which case, is time the bending of space? Do massive objects distort time? How would bending of time be observed? Would we observe it as speeding up? Slowing down? Could you do this infinitely (ie stop time)?
So much I don't fucking understand. Can anybody point me to some literature that explains any of this?
