Cranly’s eleven true Wicklowmen to free their sireland
When we hear the word “universe,” we think that means everything: every star, every galaxy, everything that exists. But in physics, we’ve come upon the possibility that what we’ve long thought to be everything may actually only be a small part of something that is much, much bigger. The word “multiverse” refers to that bigger expanse, the new totality of reality, and our universe would be just a piece of that larger whole.
Scientists have many proposals. In some, the other universes have the same laws of physics and the same particles making up matter. So except perhaps for some environmental differences, pretty much what we see here is what happens there. In some multiverse proposals, the other universes could be radically different from what we know, the particles could be different, the laws of physics could appear different. And in others—ones that frankly don’t compel me—even the kinds of mathematics that govern the physics in those realms might be different from the math that we are familiar with.
