If you think of the big-bang as the blowing up of a finite sized object,
then that would be true.

That is not how cosmologists consider the big-bang. There is nothing to
say that the universe has not always been infinite in size, but then
started expanding at the the big bang.

Even if the universe has an edge of some sort, it could have been so far
away at the time of the big bang that the expansion puts it forever
beyond Earth's light cone, meaning that we'd never see it, no matter how
long we wait.
