Answer 1

The “big bang” is a misnomer.

Everything, everywhere came into existence at once. It didn’t start in a pinpoint, and expand like a globe.

Infinite pinpoints are expanding. It’s easier to imagine that the universe is already infinite in size, you could travel forever and never reach an edge. And yet, that infinite space is expanding, even further.
