The scientists say the universe has been expanding since the Big Bang. Since our universe is made up of everything (so it's said), then the question arises as to what it's expanding inside of?

Here's another case why I think the multiverse can exist.
Couldn't our universe expand inside of a larger universe?
Otherwise how do you account for our expanding universe? Where is the room for it to expand?

To slightly paraphrase something I posted in an alternate thread:

...not only extends omnidirectionally away from our universe, but it also extends omnidirectionally away from any other context of reality imaginable (including those of a transcendent nature).

Therefore, it is “infinite nothingness” into which the universe is expanding.

First of all, of course a multiverse can exist.

Secondly, the multiverse concept does not see universes as existing within each other, but as parallel entities.

And lastly, there is absolutely no reason to assume that what is represented by the blackened area surrounding the bubble of reality depicted above would impose any restrictions on the size or perpetual expansion of anything contained within its endless and boundless reaches.

There are two definitions of a multiverse:

1. Countless universes existing side by side. This means that our own universe is only a small fraction of "the whole multiverse". In theory you could travel between them, since they don't have barriers. Each universe would probably have its own unique physical constant.

2. Our universe is a multiverse in itself. Frequencies seperate them. They are alike, but small differences makes each one slightly different from the others. The idea is inspired by quantum mechanics, and the question: Where are the particles before the wave collapses? The concept is often used in science fiction.

The concept of a small universe, inside a wormhole, in a larger universe is (as mentioned by the previous poster) not a multiverse. I actually consider the idea that it could exist at all, to be close to absurd. The time it takes to pass through the wormhole is much to short to allow any considerable action or development. And: How would such a mini universe come to exist at all? It would demand it's own physical constant! (Like I said: Absurd!)

That is a good observation. That however couldn't be a good argument in favor of multiverse since infinity can expand without changing.

Are you saying our universe is infinite?

Our universe or the multiverse should be infinite otherwise it is embedded within something bigger.
