Why is there no “Center” of the universe if there was a big bang?

I mean if I drop a rock into a lake, its makes circles and the outermost circles are the oldest. Or if I blow something up, the furthest debris is the oldest.

Answer 1

The responses you got so far are spot on and explain the subtle details of an expansion of the universe without a center with many examples.

I would like to add an explanation that is visual and has helped me to really understand what is going on:

Here you just have to align a picture with its “expanded” version and see for yourself that, whatever you do, it will seem like the expansion is moving outward of the center that you choose.
