hi everybody.

 

1) i read that the diameter of the observable universe is about 93 billion light years. But the age of it is 14.3 billion light years.

how could the universe expand itself at a speed larger than the speed of light? is it possible that the universe started not by

one singe big bang, but by several sepparated big bangs that banged together in a chain reaction, distanced from eachother, like

wwII sea mines?

 

2) at quantic level, our laws i know dont apply, but is there a field of physics dealing with the laws that apply at the macromacrocosmos?

i would imagine that if at a very small level laws change, so should they at a very large scale...

 

thanx.

Andrei

General relativity allows for faster-than-light space expansion. The speed limit c applies to bodies moving in a fixed spacetime, but does not apply to space itself.
