# People from other universes here: do they really "walk among us"?

Perhaps, the "people" you speak of are the ghosts we seem to be frightened of?

On a serious note, the multiple-universes theory is simply a conjecture backed by theoretical mathematics. No serious experiment has proven their existence at this point.

It's really much ado about nothing.

I already explained this, though I'm certain my logic can be argued with.

There are an infinite number of universes. That means there are an infinite amount of civilizations, infinite amount that learn inter-universe travel. Infinite amount that would find us and come here. That would mean their infinite mass would collapse the universe into a black hole.

Now, even if they have technology to render their mass unnoticable, keep thinking. Of the infinite aliens that come here, an infinite amount would be evil and seek to kill us all, so an infinite amount would activate their mass and collapse the universe regardless.

Clearly, this doesn't happen, which leads to 3 options.

1:Interuniverse travel isn't possible; either you can't travel between them, or there is just 1 universe.

2:There are limitations on what universes can be traveled to.

3:There are a finite number of universes.

The universe has gone from unimaginable, featureless heat to complexity and it will return in time to unimaginable, featureless cold.

I can't really fault that! Very good logic. The only explanation I could come up with is that our minds are simply too basic as of now to fully understand the way the multiverse works.I already explained this, though I'm certain my logic can be argued with. There are an infinite number of universes. That means there are an infinite amount of civilizations, infinite amount that learn inter-universe travel. Infinite amount that would find us and come here. That would mean their infinite mass would collapse the universe into a black hole. Now, even if they have technology to render their mass unnoticable, keep thinking. Of the infinite aliens that come here, an infinite amount would be evil and seek to kill us all, so an infinite amount would activate their mass and collapse the universe regardless. Clearly, this doesn't happen, which leads to 3 options.1:Interuniverse travel isn't possible; either you can't travel between them, or there is just 1 universe.2:There are limitations on what universes can be traveled to.3:There are a finite number of universes.

Very interesting. Here's another option:

4:No one wants to visit our universe.

Our universe might be considered bad or dangerous. Maybe in our universe, the Higgs Boson is not at its true vacuum state, meaning our universe could literally cease to exist at any moment (for all we know, the decay has already started somewhere and the shockwave will hit Earth tomorrow). Obviously, that would deter people from other universes from coming here.

It might also explain Fermi's Paradox. Assume that, once an intelligent alien species reaches the level of science and technology we'll reach in, say, 2200 AD, it discovers the Higgs Boson is not at its true vacuum state. It also discovers how to travel to other universes that don't have this problem and/or how to create universes that don't have the problem. Intelligent species by definition make intelligent choices, so they all leave our universe. This happens long before any of them have had enough time to colonize more than a few light years of space.

I've had a thought. Since there are theoretically an infinite number of universes, and most of us here think that travel to parallel universes will be possible at some point in the future, do you think that anybody from a parallel universe has ever or will ever visit this universe, or more to the point, this very planet? It's never really occurred to me until a day or two back.

If there are an infinite number of universes what are the odds that any inter universal travelers would pick this one?

On the contrary, if there are an infinite number of universes generating the infinite number of travelers, the odds that someone of them will pay us a visit must be relatively high.

He seems to have answered the question as to why infinite numbers of travelers haven't come to our universe, filling it up with so much mass that it collapses into a black hole.

It like a fraction whose numerator and denominator are both infinity.
