New Proof from Oxford: Parallel Universes Exist

Dcmultiverse_2 Parallel universes aren’t just the stuff of sci-fi, according to a mathematical discovery by Oxford scientists. The breakthrough is being described as "one of the most important developments in the history of science".

The parallel universe theory was first proposed back in over half a century ago in 1950 by US physicist, Hugh Everett. The theory helps make sense of the many mysteries of quantum mechanics that have left scientists scratching their heads for decades. In Everett's "many worlds" universe, every time a new physical possibility is explored, the universe splits off. For each possible alternative outcome, each one is played out in an alternate universe. The implication would mean that the number of alternative scenarios in every individual’s lives would be bizarrely and unfathomably endless.

Partly because the idea is so uncomfortably strange, it’s dismissed as sci-fi by many critics. But there are also many credible, respected proponents of the theory—a group that is continuously gaining new adherents as new research unveils new evidence. The new research stemming from Oxford now—for the first time—offers a mathematical answer that sweeps away one of the key objections to the controversial idea. Their research shows that Dr Everett, a Phd student at Princeton University back was indeed on the right track when he came up with his multiverse theory.

Dr Andy Albrecht, a physicist at the University of California at Davis commented, "This work will go down as one of the most important developments in the history of science."

According to quantum mechanics, nothing at the subatomic scale can really be said to exist until it is observed. Until then, particles occupy uncertain "superposition" states, in which they can have simultaneous "up" and "down" spins, or appear to be in different places at the same time. The mere act of observing somehow appears to "nail down" a particular state of reality. Scientists don’t yet have a perfect explanation for how it works, but that hasn’t changed the fact that the phenomenon appears to be real.

According to quantum mechanics, unobserved particles are described by "wave functions" representing a set of multiple "probable" states. When an observer makes a measurement, the particle then settles down into one of these multiple options, which is somewhat how the multiple universe theory can be explained.

The Oxford team, led by Dr David Deutsch, showed mathematically that the bush-like branching structure created by the universe splitting into parallel versions of itself can explain the probabilistic nature of quantum outcomes.

The work has another very strange implication. The idea of parallel universes would apparently sidesteps one of the key complaints with time travel. Every since it was given serious credibility in 1949 by the great logician Kurt Godel, many eminent physicists have argued against time travel because it undermines ideas of cause and effect to create paradoxes. An example would be the famous “grandfather paradox” where a time traveler goes back to kill his grandfather so that he is never born in the first place.

But if parallel worlds do exist, there is a way around these troublesome paradoxes. Deutsch argues that time travel shifts happen between different branches of reality. The mathematical breakthrough bolsters his claim that quantum theory does not forbid time travel. "It does sidestep it. You go into another universe," he said. But he admits that there will be a lot of work to do before we can manipulate space-time in a way that makes “hops” possible. While it may sound fanciful, Deutsch says that scientific research is making the theory sound much more believable.

"Many sci-fi authors suggested time travel paradoxes would be solved by parallel universes but in my work, that conclusion is deduced from quantum theory itself."

In an alternate universe they discovered that only one universe existed. Are we in the wrong one?

In the story of Indra and Vishnu, as related by Joseph Campbell in The Inner Space of Outer Space, Vishnu elaborates to Indra, in order to teach the vainglorious godking humility, a scheme of infinite universes co-existing, each with its own Vishnu, Brahma, and so on. The story is at least 3000 years old, and probably far older.

Once again: It is common usage, but "parallel" is not an accurate representation of the notion of these branching universes. If they were parallel, they could not branch, or diverge (which word is derived from a word for branching).

Oops. Sorry about that. Don't know what happened. Only submitted it once.

Words alone do not constitute science...this is a lecture in Philosophy...from a soap box, no less. Please be more selective in you meandering.

Dear Jack,

Do you suppose that there is a link between "co-existing infinite universes" (science is just now beginning to understand) and the work of Walter Cruttenden, Archeoastronomer ... The Great Year and The Binary Research Institute? Do the Yugas co-exist?

e.

They didn't prove shit that any of the alternatives like de-broglie Bohm hadn't already established...
In which there is NO parallel universes so does this mean we havve proven there is no parallel universes ?
Jesus christ get your facts straight or dont write articles

Dear Misleading:

Not so. Review paragraph 3:

"But there are also many credible, respected proponents of the theory—a group that is continuously gaining new adherents as new research unveils new evidence. The new research stemming from Oxford now—for the first time—offers a mathematical answer that sweeps away one of the key objections to the controversial idea."

They did prove that it was possible. This is an important step, because humans have a tendency to not even attempt things they consider impossible; in some cases, they can't even percieve something too far out of their realm of experience.

You can go back and kill your grandfather, just make sure your grandfather has already sired your father!
Also, your family history needs to state your granddaddy died early?

i belive that there could actually be parallel universes and i also believe that we are not alone in this great vast universe.

I've often wondered what mysteries would be evident if we could actually live in the present, but we can't, we can only exist in a past, before the light from across the room enters my eyes, times past, before the thought is registered, time has past.

Dears,

Time Travel will never be possible, cause if it was, and we change one thing by going back in time, that means one universe has just disappeared from its natural events, and if it disappeared, then the question is where did it reappear.

You must always remember that the universe is one big mathamatical equation and changing one factor can only mean you changed the formula so somehow it must balance its self once more.

That's a facinating thing to say. However, no one said that one universe would cease to exist. Wouldn't another just be created by changing an event? Just a possibility.

@ Armstrong Does that means whatever we see is 8 mins and some secs what already had past, I mean to say that whatever happens when its night are those events what we see are really present or just few secs late as compared to what we see in daylight.

The rose oil(cats eye) nebula which has been seen by the hubble telescope is millions of light years away and probably already finished. Wikipedia has got good info on this. There is possiblity that current universe is out come of that. However, creation of parallel or sequential universe seems possible. I used the word sequential. Since we are open here to talk about myths also, we may have to go back to some old myths for example in Hindus, a person has 7 incarnations. On other hand in Abrahmic religions, there is theory that there are 7 skies. If we lookinto hind u mythology, a person pass through 7 stages of life, question is does he pass through 7 incarnations in current universe or move to another universe which is parallel to ours? We may have to think of parallel and sequential universes. For the person it may be sequential if he move from one incarnation to another but actually the universe itself is parallel. Here we may need help from mathamatical calculations. The purpose is to share an idea not to hurt someones believe. Please take it positive. Thanks MSR.

well, really, if anyone moved from one time into another, they would still arrive in the present moment that they're in.

we live in the present timlesness all the time. its life, its all there is.

Mathmatical equations does not a theory make. Science is based on verifiable falsification of an hypothesis, not the metaphysical speculation and hand waving of this article and most of the field of cosmology.

kasf;kdhf shut up

I think that the theory of parallel universes if found to be true would redefine the word determinism where instead of having a linier outcomes there would be infinite posibilities of being that would not be linier

I think time travel can happen and is already happening now, in our universe, without our knowledge, by the people living in futuristic universes visiting us. By time travel I mean we will be able to get into parallel universes which is a copy of us living in the future or in the past. Assuming every thing is happening now at the same time some where( thus removing the concept of time totally). By going into one of the infinite possible options of our future (one of the infinite universes), we can see the consequences of our decisions/actions and if we do not like it, come back and change that in this universe to make the future in this universe better.If we like it our future in the universe we travel, then come back and make the same decisions in future to lead us to that kind of future.
So in fact by doing time travel into some universe we destine ourselves a certain future in the universe we come from or change the course of life in some other universe where it is still in the past.
Then in that case, it will no longer be called as time travel. It will be called as multiverse travel or hopping. The concept of time will not be there at all in multiverse hopping.And in order to do that, we need not go to some distant space in a space craft. All we need to do is create a strong energy to tear the space-dimension of our present universe and enter another space dimension,to a new universe, right here in the same space.
If we are able to achieve it, then just imagine the possibility of being able to choose the kind of universe you want to enter or check multiple possibilities of your existence. holy moly! then life would be like a computer program written to achieve the best possible solution for the best life.

I hope you guys understood what I am trying to say. I am just trying to give my thoughts on the matter.

How does this prove multiple universes exist? It does not, especially noting when adding energy to a particle the electron takes on a different position. If multiple universe did exist it would take infinite energy to cause the electrons in every universe to change positions. Because this is not apparent then means there are no other universes. What it does imply is that the basic working understanding of the particle is still a mystery. For all we know the particle could be emitting the electron as a wave and its position is an effect from the rest of the universe upon it.

Everything is possible in this world. There is no limit in space that this or that cannot happen. When we can have one universe there can be more also. If we are not aware of something or we have scientific limitation then it does not mean that that thing does not exist. May be 100 years back nobody was aware of Nebula it did not mean that it did not exist and it suddenly appear because today we have telescope. Nothing can be confirmed by 100% proof or surity. Our science is not that advance that we can move in the past and future, we know only present as we live in present. REst all we read or viewed in books and videos only.
