Morning, gang. Let’s get those science synapses firing with some layman’s terms explanation of why ‘The Multiverse is Inevitable and We’re Living in It‘:

Imagine that the Universe we observe, from end-to-end, is just a drop in the cosmic ocean. That beyond what we can see, there’s more space, more stars, more galaxies, and more everything, for perhaps countless billions of light years farther than we’ll ever be able to access. And that as large as the unobservable Universe is, that there are again innumerably more Universes just like it — some larger and older, some smaller and younger — dotted throughout an even larger spacetime. As rapidly and inevitably as these Universes expand, the spacetime containing them expands even more quickly, driving them apart from one another, and ensuring that no two Universes will ever meet. It sounds like a fantasy picture: the scientific idea of a Multiverse. But if the science we accept today is correct, it’s not only a valid idea, it’s an unavoidable consequence of our fundamental laws.

Basically:

…the Multiverse is a theoretical prediction that comes out of the laws of physics as they’re best understood today. It’s perhaps even an inevitable consequence of those laws: if you have an inflationary Universe governed by quantum physics, this is something you’re pretty much destined to wind up with.

Thus proving what I always knew: DC Comics were right all along!
