: Hi,

: The universe is infinite but on the other hand, at the begining (at the big bang), it was all concentrated in one point.
: I was wondering if their wasn't a paradox here because as the velocity of ligth is a limit you cannot go over, the entire universe should be in a sphere which center would be this point, and which radius wold be the age of the universe multiplied by the velocity of light.

:

who says objects can't move slower than light so the universe might have just an irregular shape as anything else. Still, estonians (us), have invented a laser, in University of Tartu, where light particles start moving slower than the usual ones, but they speed up over the speed of light and still finish the distance at the same time - this is called something like lightbullet, or i don't know how's it in english.
