Should you avoid alcohol when getting a coronavirus vaccine? It is not clear that we can even speak coherently about the creation of the universe, given that such an event can be conceived only with reference to time, and here we are talking about the birth of space-time itself.” At first all the matter and energy in the universe was crammed together in one … That might indicate that there's more unobservable Universe beyond the part of our Universe we can access, but it doesn't prove it, and it doesn't provide evidence for a Multiverse. “Why is there something, rather than nothing?” could be the oldest and deepest question in all of metaphysics. More logical, to me, is the bubbling, frothing multiverse situation—but okay, we still then have the same problem. It’s a big question, perhaps the biggest.

The idea that the universe simply appeared out of nothing is difficult enough; trying to conceive of nothingness is perhaps even harder. Most physicists now think that the universe began with the Big Bang.

By the same logic, nothingness is the highest entropy state around – you can shuffle it around all you want and it still looks like nothing.
