Creation Without A Creator?

If nothingness is really impossible, then the universe should not be expanding (there was no Big Bang), the universe should be of infinite expanse and age. Maybe there is some clever way to get around this.

Perhaps our resident physics can comment better, but my understanding is that the universe has energy equal to zero. And that every region of empty space can’t be empty forever so any region of empty space a whole new universe can pop into existence (one Big Bang per universe). From GR this universe is of infinite expanse and does go on forever in time.

Well not really. His main premise from QM is that nothingness is an impossible state. Eventually something has to come into existence. So why not whole universes? So before the big bang there was no space, time, matter, energy - nothing. But nothingness is unstable. So poof, out of nothing comes the Big Bang. Really amazing, it is just like God creating the universe without the God.

This is not creation from nothing. You don’t need a physicist to tell you this, as this is a philosophical question. Krauss thinks that “nothing” means “quantum vacuum plus all the laws of physics”, which is the most empty a physical world obeying our knowledge of quantum mechanics can be. This is a lot of things.

Philosophers ask different questions: where does the laws of physics come from? Where does the physical world comes from? etc
