Is there another 'you' in a parallel universe ?

The 'many worlds' hypothesis suggests the existence of countless other universes similar to ours but different.
The idea that we live in one of a practically limitless number of near-identical realities is nothing new.

In one universe for instance you may have died in a car accident last month, while in another you might have even become the President of the United States. Every conceivable outcome has happened in at least one of these universes - each version of history has played out somewhere.

In his recent book Something Deeply Hidden, physicist Sean Carroll from the California Institute of Technology delves into this concept in more detail.

The idea of parallel universes, he argues, is a definite possibility.

"It's absolutely possible that there are multiple worlds where you made different decisions," he said during a recent interview with NBC. "We're just obeying the laws of physics."
"We don't know whether the number of worlds is finite or infinite, but it's certainly a very large number."

According to the theory, each decision a person makes might split reality into two new iterations, each following a different possible outcome. On this basis, Carroll argues, parallel universes may not be situated at any particular place or time but may instead exist relative to the observer.

In the peculiar world of quantum mechanics, such a concept wouldn't be all that surprising.

"Before you look at an object, whether it's an electron, or an atom or whatever, it's not in any definite location," said Carrol. "It might be more likely that you observe it in one place or another, but it's not actually located at any particular place."

As for visiting such alternative realities however, Carroll remains skeptical.

"[They] don't interact, they don't influence each other in any form," he said. "Crossing over is like traveling faster than the speed of light. It's not something that you can do."

For there to be a "me" in another alternate universe, EVERYTHING up until my conception would have to take place exactly as it happened in my universe.  That very sperm has to meet that specific egg at the exact moment for me to be conceived.  If there is an opposite action for every decision, then there would be infinite parallels.  Most of them wouldn't have me in them, but also, another infinite amount would have a version of me in them.  Yes, there are an unlimited amount of sets of infinity and each decision would have it's own set of infinity.  It's definitely not comprehensible.

I think that quantum physics is not yet understood. The theories behind the subject by (among others) Max Planck and Albert Einstein in the early 20th century. This was a time when the notion of "dark" matter, dark energy, dark field etc had not been discovered. If you consider the wave/partial duality experiment that shows wave interference patterns forming when a single electron is fired at a barrier with double slits, is it not feasible that the interference patterns are a result of a subatomic particle reaching a higher energy level. This particle interacts with "dark" matter (which presum... [More]

I love Phillip K. Dick stories because the end is always up in the air, you have to decide for yourself what really happened.

Is there another 'you' in a parallel universe ? Only in video games

No, also in your imagination, always in your imagination.

Without a doubt I would swap places with the other identical me, surely his life can’t be worse than mine.

On the topic of ‘Quantum-Physics’; I wonder how many sub-atomic particles make up a flea-fart ????

If there is only the one universe, we have a definite problem. There are so many different values the four forces of nature, and a great many physical constants could have randomly assumed. The odds that these all came together with the right values to permit us to even exist are vanishingly remote. Yet this is supposed to have happened in only one try? I don't think so! Either there is a multiverse, or we live in an intelligently created universe.

Maybe. Sometimes I feel I enter parallel universe for no reason.

How many other values are there, and how have you determined them?   Argument from incredulity.
