At this point, if we discovered something resembling the current conceptions of parallel universe, we would probably just re-define "universe" to refer to what we traditionally think of as a universe. In much the same way that we do not have any problem with talking about sub-atomic particles; even though that is sub-atomic is a concept that does not make any sense. In this case, from the article, it sounds like ther…

>even though that is sub-atomic is a concept that does not make any sense. Can you please explain this? How is sub-atomic nonsensical? It just means "constituent particles of an atom."

That's exactly it. Atom comes from atomos, meaning indivisible; if you take the literal meaning, it has no constituent parts.

Imagine the look on Stephen Hawking 1011156B's face when he finds out Stephen Hawking 7086C published the exact same paper that he did, died two weeks later, and the combination of those events compelled scientists in that Universe to eventually master interdimensional travel, when 1011156B only got laughed at.

How is the Hawking ID generated? Which universe is used for synchronization? Do we need a new UUID level? Will the NISTs of all universes ever come to an agreement? So many questions...

Multiversally-Unique ID's are going to be so long...

but thing is we called it that because we thought there was nothing smaller than a atom.. although there is something smaller.

atoms are made of protons neutrons and electrons each which is made of 3 quantoms.

Same with universe, we think it encompasses everything but according to our current definition it might now.

And similarly, we called it a universe because nothing observable can be outside it. Unless...

The analogy is quite apt, really, just switching out bigness in place of smallness.

Depends on how many of them there are. If there is infinite, there is no MUID, if it's finite and below 2^64 then a traditional UUID should be enough to assign a UUID per universe and then assing a UUID for objects within.

There cannot be a mathematical proof of a physical fact. You can have infinite number of theories that are all mathematically correct, yet contradict each other. You need data from experiments to falsify the wrong ones. And I think that's why the article means - paper shows what experiment needs to be done to falsify some theories that assume multiverse.

Technically you might be able to do a proof by exclusion if you can show that only one of all the possible theories is sound and consistent.

I can personally assure you that String Theory is mathematically robust, and the only sound and consistent TOE; and as all other TOEs are excluded, therefore String Theory must be, and just has, been proven.

But that's pretty unreasonable as a line of argument; the derivation of a word from a long dead language has no bearing on the semantic in modern discourse. Atoms have been known to be divisible for over 100 years, the consequences of this knowledge are everywhere in our society!

I think it's commonly held that an entities Universe is everything that has or could physically interact with that entity. So, everything that is out of the light cone for you is external to your universe.
