"The Human Species Will One Day Migrate to a Parallel Universe" -- Michio Kaku

Galaxy

Like many physicists, Michio Kaku thinks our universe will end in a "big freeze." However, unlike many physicists, he thinks we might be able to avoid this fate by slipping into a parallel universe. "i

One of the most fascinating discoveries of our new century may be imminent if the Large Hadron Collider outside Geneva produces nano-blackholes when it goes live again. According to the best current physics, such nano blackholes could not be produced with the energy levels the LHC can generate, but could only come into being if a parallel universe were providing extra gravitational input. Versions of multiverse theory suggest that there is at least one other universe very close to our own, perhaps only a millimeter away. This makes it possible that some of the effects, especially gravity, "leak through," which could be responsible for the production of dark energy and dark matter that make up 96% of the universe.

"The multiverse is no longer a model, it is a consequence of our models," says Aurelien Barrau, particle physicist at CERN

While it hasn’t been proven yet, many highly respected and credible scientists are now saying there’s reason to believe that parallel dimensions could very well be more than figments of our imaginations.

"The idea of multiple universes is more than a fantastic invention—it appears naturally within several scientific theories, and deserves to be taken seriously," stated Aurelien Barrau, a French particle physicist at the European Organization for Nuclear Research (CERN).

There are a variety of competing theories based on the idea of parallel universes, but the most basic idea is that if the universe is infinite, then everything that could possibly occur has happened, is happening, or will happen.

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 occurs, but that hasn’t changed the fact that the phenomenon does occur.

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 existence of such a parallel universe "does not even assume speculative modern physics, merely that space is infinite and rather uniformly filled with matter as indicated by recent astronomical observations," Max Tegmark, a cosmologist at MIT in Boston, Massachusetts concluded in a study of parallel universes published by Cambridge University.

Mathematician Hugh Everett published landmark paper in 1957 while still a graduate student at Princeton University. In this paper he showed how quantum theory predicts that a single classical reality will gradually split into separate, but simultaneously existing realms.

"This is simply a way of trusting strictly the fundamental equations of quantum mechanics," says Barrau. "The worlds are not spatially separated, but exist as kinds of 'parallel' universes."

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. Some Oxford research—for the first time—recently found  a mathematical answer that sweeps away one of the key objections to the controversial idea. Their research shows that Everett was indeed on the right track when he came up with his multiverse theory. 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 strange implication. The idea of parallel universes would apparently side-step 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. 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 continually making the theory 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."

The borderline between physics and metaphysics is not defined by whether an entity can be observed, but whether it is testable, insists Tegmark.

He points to phenomena such as black holes, curved space, the slowing of time at high speeds, even a round Earth, which were all once rejected as scientific heresy before being proven through experimentation, even though some remain beyond the grasp of observation. It is likely, Tegmark concludes that multiverse models grounded in modern physics will eventually be empirically testable, predictive and disprovable



Comments

Of course it will! It is also called death.

Highly unlikely. There is no such thing as parallel universes. Such universes would be part of the universe.

Strange things observed in new realities is not something new. When Europeans started to sail the world seas they also discovered new realities with weird things. When electricity was discovered weird things were observed. We now know that exotic species are not supernatural monsters or mermaids. We now know that electricity happens because of electrons.

From our point of view modern physics is very advanced. It couldn't be different. Yet, this area is still brand new, hardly discovered and a lot of things are not explained yet. I don't see why the existence of monsters, mermaids or aether should be invoked to explain things that will probably be rather simple to understand 100 years from now. It almost feels like wishful thinking.

The universe as we see it is the most probable outcome of infinite possibilities on quantum scales and beyond. An elementary particle may exist in an infinite number of universes, yet these universes would have no dimensions. Such elementary particle would be these very universes. Solely on their own they wouldn't really exist since there are no relations, except with 'self'. Mathematics show that that is more than enough to invoke a massive set of laws, rules, probabilities. In 'our' universe, or multiverse, identical elementary particles interact with each other which invokes reality as we experience it. Differences are expressed in space and time.

A single imaginary particle would have no dimensions on the outside but infinite on the inside. Two of these particles would invoke just one spatial dimension on the outside, not three. Things get different with more particles. Every single particle would relate with every other one. Relations would express themselves in three spatial dimensions. Differences in differences invokes times where the average would invoke universal time.

We most probably live in pure mathematics. A fractal-like structure of infinities. Since we are part of this reality in particular, limiting ways we observe the universe in a particular, limiting way. Yet, maybe the universe is nothing else than a projection in our brains of something very simple in nature but very hard to express with ordinary things.

There is no such thing as a paradox. The future has not been written and therefore when you go back in time and kill what may or may not have become your grandfather (the future has not been written so there is no guarantee anyway)there is no problem but there is a new future; the one you knew had never been written and now never will be, but the minute you entered what was the past it becomes the present and you are written into that present so you continue to exist regardless. What we cannot do is "jump" forward although you can travel there at a greater speed than we all do anyway (e.g. travelling at the speed of light and seeming to jump forward)but you absent yourself and therefore can't go and see what you have done. You will have had no impact on that future and can look back on the date your seemingly disappeared.

if there are parallel universes, what do they exist in? if i am a pair of shoes in a box and discover i am surrounded my more shoe boxes, chances are i exist in a shoe store.

It's what all the intelligent and very trendy and hip intelligent races did...skip off to another universe...kinda like the Rapture...why have we been left behind you wonder? Watch Jersey Shore...

I hope our scientists can find a unified theory soon. I want to go to another universe!

Travel to where, it is very possible that it would be impossible to go to the next Universe, it may be so different that you simply can't exist there. And this whole idea of escaping this Universe before it freezes over is absurd, how many Billion years will that be from now ? Why don't they try living out the decade first ?!

Hey, that's great, Mr. Kaku. Er, you first, so we can see how it goes. :)

lol, an other consequence of Fukushima disaster

Interesting therory. I think the only way we can move on to a new para world is by when we pass away. We could never survive anything that has to be faster than light not in body form anyway.
The first 9 months of our lives we r in a womb which is our world then. Suddenly out of the womb in to next part of our lives. Then when our body dies then our energy which maybe could move faster than light into the next stage of our existance maybe into a para world. Thats my therory!

Cientist should quit Lsd for a new comprehension of the solid grey mass oportunity to drink freud in social comments of theories that never go out when asking a woman.

Re; The above comments.

Uh?

Sounds like a poor translation Cientist.

Let's hope it's sooner than later! Beam me up, Scotty. place of refuge 2012 dot com

Love to read his books a great scientist if want know whats is up in the future

I'm confused if the universe is expanding are we not moving along with it? if so then surely unless things are moving at different speeds nothing in the night sky would change.

And in measuring the age of the universe, who's to say that the farthest reaches of space we have encountered thus far is mearly just that, the farthest reaches!

It could be going on trillions of light years past our lowly tech.

That oriental science guy ‘sounds’ pretty smart.
But what I want to know is ...
... why is he incapable of telling the truth?

Scienter -->
Latin: actual or guilty knowledge; knowingly.

Any reference to that guy … is a sure sign of B.S. … he’s like Stephen Hawking, only slightly more coherent.

ever been told hey I seen u the other day @ such and such place and u no u havent been ther yet OR HAVE U...

Have you ever launched more than one app on your computer? Yes, parallel universes or dimension ARE like apps in your PC. They are separated but not by space or time.

Reading on the subject of "Entanglement" is a good place to start for grasping the concept of parallel universes. Space/Time does not exist everywhere (or should be stated as localized and finite), stuff exists where matter, space and time doesn't.

You can't get there from here.

Wow! An avalanche of declarations rejecting an idea before we've even understood it. Wouldn't it more fun, and probably more fruitful, to ask, 'What if?' and really think about as yet untapped possibilities? Keep going, Michio.

Parallel universes is just a theory for now but in my eyes it's not so crazy or scifi. It's just hard to take in such info when it is not tangible. We cannot see atoms or the main things that make up this earth with the unaided eye neither can we see what time is without numbers. We cannot see what surrounds us maybe there is other things we cannot see, there for it's hard to calculate things we can not touch or observe and measure but it may still exist with out our knowledge. We still have yet to discover all the creatures of the sea and earth. All we can do is assume predict and imagine for now till these things are discovered. I believe this is an awesome idea, maybe not for skeptics though. Parallel universes are most logical when it comes down to accurate calculations. If these calculations are replaced with something else then the calculations become incorrect so it must mean these things are real.

UNIQUE PARAMETERS
-- James Ph. Lotsybar

There is only one answer to creation.
Though we don’t nearly understand it yet,
there’s but one elegant variation
emerging from initial values set
that even allows molecules to be,
much less achieve complexity of life,
or suns to burn their planets distantly
with not too much but with the needed strife.

It’s easy to view things anthropically --
nothing explained, just looked at in reverse --
or declare we see things myopically --
anomalies blind to our multiverse.

Whether we’re destined or a doubtful freak,
as far as we know so far, we’re unique.

There are some things that are just happening on CERN tests that are arguable to the existence of a parallel universe, I do support the above idea of say first: "what if" and let all the possibilities be possible.

If you were an habitant of a terraplane and would live just in a plane world, you wouldn't be able to explain what the heck happened if you had travel in stright line and then you encountered in the exact point you started your journey, how that would be possible if you live in a plane world?? But if someone comes to you and says you: wait on, that was because your plane world is wrapping a tridimensional world called sphere, then that possibility is now possible. That is what comes to mind when Michio says that the nearest parallel universe is perhaps just a milimiter away from ours!
