Infinity

The question of whether the universe is indeed infinite or finite. Could the universe be contained by some sort of an edge or boundary, and if so what is beyond, if there is a beyond? Can there be truly nothing? What are the possibilities? Perhaps there are an infinite number of other universes, possibly existing in different dimensions.

Have you ever wondered how large the universe is? and if it really is infinite? Whilst it is still unknown, it looks very likely that our universe is infinite, but what about the possibility of infinity in both directions, from the infinitely large to the infinitely small?

It is thought that the big bang was the beginning of space, matter and time, and that all space and matter were created from absolutely nothing. How can we conceive of something from absolutely nothing? New understanding suggests that this might not be the case, and there could have been something before the big bang.
