We have never observed infinity in nature. Whenever you have infinities in a theory, that's where the theory fails as a description of nature. And if space was born in the Big Bang, yet is infinite now, we are forced to believe that it's instantaneously, infinitely big. It seems absurd.

I'd like to convince you that the universe has a soundtrack and that soundtrack is played on space itself, because space can wobble like a drum.

The Earth isn't an infinite sheet that carries on for ever, but it doesn't have an edge, either. It's compact and connected.
