Physics, Astronomy & Cosmology / Way should there not be a center of the universe?
« on: 04/12/2009 14:06:01 »...as with a normal explosion - all thing moving outward somewhat evenly in all direction. If you turn the arrow of time then backward all things move back to the center of the explosion. So in other words even if all objects in space are moving away from each other as space expands, somewhere logically it all started as a singularity and all things move out in all directions somewhat evenly so again why no center of the universe?

This is how I understand it, but I could be wrong: Imagine the universe as represented by an inflated balloon which has spots drawn all over it to represent the galaxies. When you deflate the balloon, all the spots move inwards towards a central point. Physically, the deflated balloon exists inside a room, but in reality the entire universe has just collapsed in on itself and there is nothing outside it to act as a reference point, therefore no centre.
