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.”

Given the speed the earth move through space I don’t see how you would get the space and time to align for materialization on a past earth.

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

"Cause it cost like 2 Billion Dollars., Sheeesh."

I believe time to be a human construct.

I was taught in classical physics that time is simply the movement of a system from a state of higher energy to higher entropy. To "go back in time" would mean to be able to create energy from chaos, to unburn the steak, unpop a balloon, and unring a bell.

It's ludicrous to even contemplate.

Let alone all this hokum about multiple universes ...

This was central conceit of Michael Crichton's novel Timeline. They weren't really "time traveling". They were going into a side universe where it was still medieval France simultaneously with the modern era of "our" universe. A person was destroyed at the quantum level here, then "faxed" through holes in Wheeler Foam into the "dark ages France" timeline.

Sounds pretty cool. Except that at one point one of the heads of the project confesses something rather dark: that they have to destroy a person in order to recreate them elsewhere... but they don't know who is doing the recreating. It's not technology which THEY possess themselves. So when they send one of their marines - a female incidentally - to scout ahead, they are destroying her existence and that's ANOTHER marine from somewhere else in the multiverse who is coming back on the return leg. From a timeline almost precisely identical.

Probably one of Crichton's best novels. And among his scariest.

If I could, I’d like to go back to the Allman Brothers playing Fillmore East. Best live record I’ve ever heard - must have been amazing in person.

1. The act of traveling back if it happens likely won’t have an effect per rules of the universe that say what has happened is past.
2. Suppose you can travel back and change something - this probably creates a NEW parallel reality. You may be able to come back, but you haven’t changed YOUR past.
3. Let’s suppose going to the past is actually an alternate dimension for us. There are a LOT of reasons going back in another timeline or even a parallel universe in current time is a bad idea.

The only way you go back in time is if it doesn’t affect the timeline. Miscalculating the position of the Earth means your time traveler is floating in space light years from Earth, embedded in Earth’s crust, or if lucky, floating in the atmosphere hurtling toward the surface.
Too many stories assume you’re standing in the same spot so it will be the same spot there, not a dinosaur standing in that same place or mangrove forest you now merge with.

"Given the speed the earth move through space I don’t see how you would get the space and time to align for materialization on a past earth."

I've said such many times regarding time travel in our known Universe. Not only does the Earth revolve around the Sun. The Solar System revolves around our galaxy, the Milky Way. Then, our galaxy is moving through the Universe at tremendous speed. Without the incredibly complex time/space computations, you could wind up in space or in the middle of another cosmic body and not the exact place you left on Earth.

There was a movie called, "The Philadelphia Experiment", when a Navy ship came back to its day from future time travel, and half the crew's bodies/atoms were interlaced with the atoms of the ship.

Again, time is a human construct. It is not malleable nor fungible. Doing the backward math of the galaxies' travel from the Singularity, time does not exist as a universal force like mass, electro-magnetism, light photons, and the unsolved physics of gravity.

As for parallel dimensions if they are not made up of our known forces, what are they made of? Pure energy? Hey, what do I know? Like I said above, that could explain UFO's. Question: If from a different plain of existence, why must they have so many lights on the outside that is witnessed? Or is that their cross-dimentional time-traveling power of propulsion?

Still think its physicists trying to reconcile their math equations with theories, much like climatologists with their models of global warming.

I did see something once on the science channel where a physics guru suggested the spacial problem may be overcome with a beacon of sorts. But then you could only travel to a time the beacon was active.
