Time travellers could use parallel dimensions to visit the past, scientists claim

Physicists reveal sensational findings which could allow science fiction dreams to become reality

Professor Howard Wiseman and Dr Michael Hall, from Griffith University’s Centre for Quantum Dynamics, claim that the idea of parallel universes is more than just science fiction.

Fellow researcher Dr Dirk-Andre Deckert, from the University of California, helped further the researchers’ theory, which goes against almost all conventional understanding of space and time.

If there really are multiple, interacting universes, then it would be possible for time travellers to visit Earth, and every imaginable scenario would be played out in a parallel universe at some point.

The team’s ‘Many Interacting Worlds Theory’ provides a whole new perspective on the ideas underpinning quantum theory, a notoriously complex strand of physics.

Professor Wiseman said: “The idea of parallel universes in quantum mechanics has been around since 1957.

“In the well-known ‘Many-Worlds Interpretation’, each universe branches into a bunch of new universes every time a quantum measurement is made.

“All possibilities are therefore realised – in some universes the dinosaur-killing asteroid missed Earth. In others, Australia was colonised by the Portuguese.

“But critics question the reality of these other universes, since they do not influence our universe at all.

“On this score, our ‘Many Interacting Worlds’ approach is completely different, as its name implies.”

According to the theory, our universe is just one of many enormous worlds, with some identical to our reality and others completely different.

The Express reports that the worlds are all real, and all on the same timeline, but interact when they essentially bump into each other.

Dr Hall believes that the group’s sensational theory fits with current scientific understanding, offering a new perspective rather than rewriting the physics rule book completely.

He said: “The beauty of our approach is that if there is just one world our theory reduces to Newtonian mechanics, while if there is a gigantic number of worlds it reproduces quantum mechanics.

“In between it predicts something new that is neither Newton’s theory nor quantum theory.

“We also believe that, in providing a new mental picture of quantum effects, it will be useful in planning experiments to test and exploit quantum phenomena.”

Here's a further explanation of the Many Worlds Interpretation of Quantum Mechanics...

From Wikipedia

The many-worlds interpretation is an interpretation of quantum mechanics that asserts the objective reality of the universal wavefunction and denies the actuality of wavefunction collapse. Many-worlds implies that all possible alternate histories and futures are real, each representing an actual "world" (or "universe"). In layman's terms, the hypothesis states there is a very large—perhaps infinite[2]—number of universes, and everything that could possibly have happened in our past, but did not, has occurred in the past of some other universe or universes. The theory is also referred to as MWI, the relative state formulation, the Everett interpretation, the theory of the universal wavefunction, many-universes interpretation, or just many-worlds.

The original relative state formulation is due to Hugh Everett in 1957.[3][4] Later, this formulation was popularized and renamed many-worlds by Bryce Seligman DeWitt in the 1960s and 1970s.[1][5][6][7] The decoherence approaches to interpreting quantum theory have been further explored and developed,[8][9][10] becoming quite popular. MWI is one of many multiverse hypotheses in physics and philosophy. It is currently considered a mainstream interpretation along with the other decoherence interpretations, collapse theories (including the historical Copenhagen interpretation),[11] and hidden variable theories such as the Bohmian mechanics.

Before many-worlds, reality had always been viewed as a single unfolding history. Many-worlds, however, views reality as a many-branched tree, wherein every possible quantum outcome is realised.[12] Many-worlds reconciles the observation of non-deterministic events, such as random radioactive decay, with the fully deterministic equations of quantum physics.

In many-worlds, the subjective appearance of wavefunction collapse is explained by the mechanism of quantum decoherence, and this is supposed to resolve all of the correlation paradoxes of quantum theory, such as the EPR paradox[13][14] and Schrödinger's cat,[1] since every possible outcome of every event defines or exists in its own "history" or "world".

I could binge watch the Sliders series.

The short lived but good series Time Trax played on the idea somewhat as well.

How do I go back and not marry my ex, but still have my kids now?

I guess if I’d shot her when I first wanted to, I’d have been out by now, still had my kids and not her.

Did George Harrison, a member of the Beatles, time travel to tell us this?

the problem is interacting

parallel..... yes

interacting..... only by designated phantoms. Odo is one

This article is humorous... The author is making the same mistake as Einstein. They automatically assume multiple universes as they are missing the main variable, the frequency of consciousness of the viewer.

My Father’s mansion has many rooms and they are all right here in this reality. One must merely tune their consciousness to perceive and enter the alternate reality.

If we could sell this to snowflakes who wish to go back before Trump was elected, we could make an absolute fortune.

Silly. Can never be proven.

In laymen’s terms nothing has any meaning at all except what you give it at the time.

That’s not even a theory. Wild speculation is more accurate.

Any time a sci-fi show gets into time travel, it is best that you try not to think too much.

But, if they can return, would they remember what they learned in the past? Otherwise, it’s just a thought experiment.

Question: Why haven’t we been visited by an infinite number of travelers from all the universes that have mastered this?

Its obverse can be proven by positing the overdetermination of cause and effect. In this scenario every act is substantially overdetermined by every prior overdetermined act. Sadly, on this continuum there is no free will. Ah well, give a little take a little.

Kind of moot because the time traveler wouldn’t change events in his own timeline.

How could you be sure you came back to the right dimension?

Wild as speculation is all it is: If I say ducks are superior alien life forms here to observe us, I believe my “theory” is just as valid. At least that is what the talking wine bottle told me.
