Theoretically easier to travel to an alternate universe according to the diagram.
Getting to a multiverse might be even harder though if that diagram is correct and there is an inflating empty space.

If Occams Razor is to be applied. A parallel universe must be on the outside the fabric of this universes reality assuming space time is the fabric.

We can't even reach the edge of the observable universe because of the very small acceleration of expansion; this is called the cosmic event horizon.
In eternal inflation -- the most popular scientific multiverse theory -- it is even worse: the space between universes is still undergoing inflation, with distances growing rapidly and exponentially.

We won't even escape this solar system. The only thing to do is to hide our asses in a giant computer and live in simulated reality.

Thanks for the response.
I didn't assume there would be much certainty in either position but it's interesting to me because it 's at the cusp of our understanding.

Do you assume that a parallel universe will have the same composition as ours?
I am talking about the cosmic laws here.

We might not even be able to exist in a parallel universe.

I'm just wondering if it is theoretically possible. It doesn't have to be likely or a necessarily tidy framework.

I mean it's an out there question. I'm sure no one will have a certain answer.

It's pretty much going to be the last hurdle if a civilization is ever perfect enough to survive indefinitely in our universe.

It's basically an updated version of Asimov's Last Question.

It would probably violate conservation of mass.

This is simply a connection between arithmetic and topology

This was probably the most elegant and mesmerising thing I've seen all year.
