The root of the idea is in explaining why our universe's physics are so finely tuned to allow a universe that can end up producing something like us. The odds that our universe would be this make-up, rather than another, are enormous. So either we're super special or, taking the "as above so below" notion, every potential universe make-up exists and we are seeing this one because it's the only one where we can emerge. The notion of energy ("energy to maintain itself") might not even apply to other universes because their physics are unknowable. And whether energy exists between universes, now we're in the realm of "just making it up."

In terms of the theories that grow out of that and how everything is rationalized and explained, honestly it's untestable and pretty useless from a scientific view. If something is in another universe, by definition, we cannot access it. All we can do is infer the possibility but never get closer than "maybe." It's an interesting idea but what's the point? Whether it is true is inaccessible knowledge.

No... we have statistical proof that it is the way it is. We have zero proof it could arise a different way.

So far the laws of nature don't fluctuate.

Given how we understand the way nature works. Our universe and time is the ONLY way for it to turn out; unless we prove other universes.

Furthermore there is no reason to think we couldnt detect other universes. Some speculate that may be the cause of dark matter. Hell it could explain quantum entanglement.

That’s what they’re saying though. Laws that govern nature is measured in THIS universe. We don’t know if the laws works differently in another.

Thes laws of nature doesn’t fluctuate in THIS universe

If thats what they are saying... your statement i responded to is wrong.

Which was why i said it

But to be clear. Evidence shows that if there was another universe it would have to follow our physics. Because there are no other instances of anything different.

That’s a different multiverse theory where different areas of a potentially infinite cosmos have different laws of physics. I believe the OP is referring to the Everettian multiverse where instead of the wave function collapsing the cosmos “branches” into multiple universe. In this model the laws of physics don’t change.

It rubs people the wrong way for various reasons, mostly because a huge number of universe seems unreasonable.

There is yet another idea based on string theory. It proposes that the universe has more than 4 dimensions, but the additional ones are "rolled up" to quantum size. It would be possible that different sets of four out of ten dimensions exist, with different ones rolled up. These universes would be "perpendicular" to ours and thus unobservable.
