It’s hard to build models of inflation that don't lead to a multiverse. It’s not impossible, so I think there’s still certainly research that needs to be done. But most models of inflation do lead to a multiverse, and evidence for inflation will be pushing us in the direction of taking [the idea of a] multiverse seriously.

The question of the origin of the matter in the universe is no longer thought to be beyond the range of science - everything can be created from nothing. It is fair to say that the universe is the ultimate free lunch.

The Big Bang theory says nothing about what banged, why it banged, or what happened before it banged.

It's actually safe to create a universe in your basement.

Despite its name, the big bang theory is not really a theory of a bang at all. It is really only a theory of the aftermath of a bang.

Space is certainly something more complicated than the average person would probably realize. Space is not just an empty background in which things happen.
