I meant to be speaking of these quantum fluctuations. If they occured and created our universe, they will have created an infinite amount if the universe is infinite.
And infinite amount of what?
Since you think the universe is finite, you do agree that there is an "outside". We'll call the outside the void, where there is nothing. If quantum fluctuations occured in the void to make this universe, why can't it be happening again.
1. I'm not sure our common sense idea of "outside" works here. IOW, if 'nothing' is the absence of spacetime and matter/energy, I'm not sure there is anything left of the "void" after the universe appeared.
2. However, if there is, I can't see any reason more quantum fluctuations couldn't make more universes.
Or maybe, it is not dimensional at all. The expansion occured from a single point, and can only occur from a single point. But, now we have many points existing in our uiverse "bubble". Will it continue to expand?
The data says the universe will expand forever.
However, here again is where our common sense is a hindrance. When you say "single point" you are implicitly talking about a point within an
existing spacetime. What "single point" is meant to convey is that the universe was infinitely small at its inception.
Our "bubble" refers to what we can see. Since it is spacetime exanding, at some point from us the velocity of spacetime expanding is greater than that of light. So we can't
see beyond that because the light emitted beyond that can't ever get to us.
And no, this is not a violation of Relativity. Relativity refers to objects moving
thru spacetime. But here we have spacetime itself expanding.
