Does each universe have their own Infinity Stones?

No. The Infinity Gems/Stones only operate within their home universe. Darkseid discovers that the Infinity Gauntlet operates in a different universe from his own, and is thus worthless to him. And there are multiple sets of Infinity Gems/Stones, from their own universes.

Are the Infinity Stones useless outside of their universe?

It’s pretty well established in the comics that the Infinity Stones are useless outside of their universe. The only reason they worked in Endgame was because they are from the same universe in a shared/same timeline. The TVA is outside of that universe.

How did Ultron use the Infinity Stones in different universes?

First of all, Ultron isn’t using the Infinity Stones to manipulate other universes. Instead, he’s using the stones to give himself more power and abilities, so technically, as a being of his own universe, he’s still using the power of the Infinity Stones within his own universe.

Why does the Infinity Gauntlet not work in other universes?

The infinity gems have power over everything else that came from the same being. Other realities in the marvel multiverse (or even DC) would have not originated from this being, so the infinity gems do not have power over them.

Do Infinity Stones work in the multiverse?

No. The Infinity Gems/Stones only operate within their home universe. Darkseid discovers that the Infinity Gauntlet operates in a different universe from his own, and is thus worthless to him.

Is the MCU’s multiverse based on real physics?

The MCU took that one step further, with Endgame ‘s time travel and Loki ‘s multiverse very loosely based on a real-world interpretation of quantum physics known as the “many worlds theory.” A different quantum outcome (read: result) in a test results in a slightly different reality.

Is it possible to avoid the multiverse?

“You almost can’t avoid having some version of the multiverse in your studies if you push deeply enough in the mathematical descriptions of the physical universe,” he says. “There are many of us thinking of one version of parallel universe theory or another.

Do other universes exist?

Brian Greene: A Physicist Explains ‘The Hidden Reality’ Of Parallel Universes It is possible that there are many other universes that exist parallel to our universe. Theoretical physicist Brian Greene, author of The Elegant Universe, explains how that’s possible in the new book, The Hidden Reality.

Is there such a thing as a parallel universe?
