How Many Multiverse Are There?

Our universe is big. It’s huge. It’s massive. And it’s expanding. But expanding into what? Does our universe resemble a balloon, expanding out into some grander space? Questions like this may seem simple, but they have stymied scientists and philosophers for centuries. From what we mean by “universe,” most people think of the things we can see — stars, galaxies, everything between that. But there is a limit to what we can observe. Light from the most distant galaxies has traveled billions of years to reach us, but the light has not had time to arrive beyond a certain distance. That’s the edge of our observable universe, the portion we can study. But what’s beyond that edge? Is there more? Or is there... nothing?
