So,I'm kinda confused here... Is the idea that we could be the 1000,000,000 universe or the 1st universe?

The multiverse theory says that the multiverse is continually creating new universes so we could be the first universe but its improbable. If this is true then the universe will eventually die out and then disappear from the multiverse to rejoin the cycle of creating universes over and over again

Depends of which THEORY you want to believe.

I tend to believe there is only ONE Universe, and the Big Bang was just an event that occurred. The Big Bang was not the creation of the universe or the creation of time.

The Universe has always existed and was not created. The Universe goes through a series of evolutionary steps, and the Big Bang is just one of those steps. There will be another Big Bang. Currently the Matter in the Universe is expanding, soon it will slow down and start collapsing. When it fully collapses there will be another big bang and the process will start over again. Big Bang to Big Bang takes 100 Billion Billion years.

If your supporting the big bang theory (which I don't) then there has to be a big crunch as well if you keep the Multiverse/bubble theory out of the question and only focus on BB then we could be the 1,000,000,000th universe, if you are including the multiverse theory maybe in this universe the big crunch won't happen and we live off peacfully.

If this is not the answer you wanted then I misread the question so please tell me if you didn't want this answer!

The big bang theory is, so far, a correct explanation for this universe. The same theory could certainly be true for other universes.

The multiverse theory is one that proposes many universes, each completely independent of the others.

The Big Bang theory does not address and does not depend upon how many universes there could be.

The person above me used the word speculative and that certainly does apply to this kind of question. Once one begins to speculate about multiple universes, there is no particular reason to speculate that they are all in one time series. There could be trillions of new universes (big bangs) starting every microsecond and zillions of universes existing at the same time. Pure speculation.

The idea that our universe is the first of many universes is absurd. An appreciation of the Mediocrity Principle is needed here.

It's apart from the Big bang theory which is concerned with our Universe alone.

When we go beyond it, we are in a very speculative realm.

It is the first and only one.

I think it is one of those in between.
