I can barely grasp the concept of infinite, let alone space time...
Branes: An object, which appears to be a fundamental ingredient of M-theory, that can have a variety of spatial diemensions. in general, a p-brane has a length in p dierections, a 1- brane is a string, a 2-brane is a surface or a membrane, etc.
A good example of Space-time is the bending of light. Imagine a peice of grid paper, held loosely with a marble in the middle. The paper will slope down, and that is a good example of a Massive star bending gravity, which in term effects space and time. When light goes near it, it is bent by the curveature of space-time, which is effected by the massive star. A black hole is basically a hole in space-time, or a hole in the grid paper, which leads to a different peice of grid paper. the 2nd peice of grid paper is a different dimension. a good example is like 2 funnels, with the small ends connected together. When a black hole forms, it has 2 dimensions, but which one was created first? is our universe created by a black hole or is it a line of infinitely created black holes forming infinate universes?
Still, I do the best I can with it, and still get confused and set it down before I go insane...
