Question

If there was a Big Bang, shouldn't there be a large void in the center of the universe?

Answer 1

If there was a center, yes, but there is no center.

Explanation:

I know this is frustrating to say but the big bang cannot be easily visualized, because we instinctively think in Newtonian terms. Matter was not blown during the big bang, it was space itself. And it didn't explode, rather it expanded uniformly.
