CERN's LHC: "Parallel Universes Could be Hidden Within the Four Dimensions"

Universe-NASA-photo-c1079 "The multiverse is no longer a model, it is a consequence of our models.”

~Aurelien Barrau, particle physicist at CERN

Physicists probing the origins of the cosmos at CERN's Large Hadron Collider hope that next year they will turn up the first proofs of the existence of concepts once reserved for the scifi world. Despite centuries of increasingly sophisticated observation from planet Earth, only 4 per cent of that universe is known -- because the rest is made up of what have been called, because they are invisible, dark matter and dark energy.

Billions of particles flying off from each LHC collision are tracked at four CERN detectors -- and then in collaborating laboratories around the globe -- to establish when and how they come together and what shapes they take.

The CERN theoreticians say this could give clear signs of dimensions beyond length, breadth, depth and time because at such high energy particles could be tracked disappearing -- presumably into them -- and then back into the classical four.

Parallel universes could also be hidden within these dimensions, the thinking goes, but only in a so-called gravitational variety in which light cannot be propagated -- a fact which would make it nearly impossible to explore them.

As the Large Hadron Collider (LHC) at CERN near Geneva moves rapidly into high gear this year and beyond, they are talking increasingly of the "New Physics" on the horizon that could totally change current views of the Universe and how it works.

Several of the world's leading cosmologists believe that we are but one of many universes. As yet, as we know, there is no evidence of there being other universes out there. Some versions of this theory suggest that there is at least one other universe very close to our own, separated perhaps by a membrane as little as a millimeter away, which, if true, could be detectable by some energy or forces such as gravity leaking through. In fact, as predicted by brane theorists, this "leakage" could be responsible for the production of dark energy from a parallel universe, its influence felt in our own through its gravitational pull.

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 continually 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.

This clearly describes two different, non-exclusive models of alternate realities: those separated by "superspace" (such as the postulated parallel universe separated from ours by a millimeter), and those that are alternate branches of time based on quantum mechanics.

(Interestingly, I make a clear distinction between the two in my novel; it's even a minor plot point. Click on my name below to read more about it.)

Some of the remarks and statements here do bring up a couple of philosophical points that apply in general, but in this case they're pivotal. First, just because there's no proof of something doesn't mean it doesn't exist. Second, just because a story is fantastic-sounding doesn't mean it's untrue.

The scientists here have gotten as far as they have because they're open-minded about what they'll learn. Already there have been reports of learning small chunks of data, and as the LHC work kicks into full gear they'll get larger chunks, and possibly some true answers to their most pressing questions -- and from there, some practical applications that only we science-fiction authors have dreamed of.

What kind of applications? If I knew that, I'd probably be working for CERN. I can hazard a few semi-educated guesses: sustainable quantum computing, quantum entanglement communication, teleportation, space-warp travel, time travel, zero point energy production... the list goes on. We may even learn how to do things that wouldn't seem connected, such as regenerate severed limbs, cure prion-based illnesses, or build affordable structures that are more resistant to hurricanes and earthquakes.

There may even be some applications that nobody's come up with yet. As recently 300 years ago nobody could have conceived of many of the things that we do today with electricity, nuclear science, and the little bit of quantum physics we now know. The computer I'm writing this on, and the one you're reading it on, use principles that we now take for granted but were beyond the wildest imaginings of anyone of that time. Just the ability to manipulate data on a scale necessary to put man on the moon would have seemed impossible back then, but now that computing power fits in a pocket.

i like turtles

Maybe this is a solution to the Fermi Paradox - when an alien civilization discovers how to cross into other universes, they leave our universe in search of the "statistical heaven" that exists out there in infinity.

what is real? how do you define real? If you are talking about what you can feel, what you can smell, what you can taste, and see. Then real is simply electrical signals interpreted by your brain.

Multi-universe theory has always intrigued me. It can perhaps be a very good explanation for probability as well as imaginative thinking, as well as leave room for the possibility of life and the universe as we know it without "god"

The initial conditions set by the singularity that spawned our Universe and probably a multitude of others set the direction of our time as always into the future.

Changing the direction of Spacetime will mean crossing Event Horizons. So far as we know this can only be achieved via a Singularity.
If we survived the singularity navigation would be a bitch.

Jesus is Lord and saviour

^^So there must be a Universe (or an infinite number of them actually) where Jesus is not lord and saviour. Long live Science!

hey, is it just me or does that blue mass look like a giant hand?

Just because a paradox exists doesn't mean it has to be resolved. Going back in time to despatch ones Grandparent may be 'hypothetically possible' with time travel, but the act of 'seeing' through any such membrane doesn't give any rights to actually transit the same.
IE: Cause and effect stay in their own dimensions, but parallel realities can co-exist, in an infinite universe.

It can be argued that because any 'clump' of matter ( planet, star etc.) has finite dimensions , that all matter in the universe, if theoretically 'clumped', possesses total finite dimensions as well. This would mean that space-time could be infinite, and contain a finite amount of matter. This would not necessarily infer that everything that can happen has happened or will happen , just because the possibility exists it does not mean that possibility will necessarily be realised. Unobserved particles cannot be said to behave more probably one way or the other, simply because they are unobserved, to say that observation affects the behaviour of sub-atomic particles is to directly infer that unobserved particles will not necessarily behave in an expected way,not only that but the other main inference is that particles can occupy more than one position simultaneously , until observed , whereupon such observation forces the particle to 'choose' its position,I would say that this has much more to do with our limitations in accurate observation of such phenomena than it has to do with whether or not they can occupy more than one position at the same time.

The idea that gravity can 'break-through' from a parallel universe/reality can be shown to be unsound, it was recently shown why the search for 'gravitons' has been fruitless, what we call gravity is an effect generated by a localised mass bending space-time around it,as Einstein said, " Everything moves in straight lines through curved space-time" So , gravity, as we have always thought of it, does not exist, but the effect that we attribute to gravity does.

So with an infinite number of realities in the multiverse where any thing can happen, i get to meet and marry and have lots of kids with Summer Glau or Jeri Ryan! That gives me a nice warm glow. Fabulous and it happens an infinite number of times!

The idea of splitting universes? I'm not sure. Perhaps identical, but separate universes with individual big bangs that just happened to diverge away from each other at a certain point? So rather than single universes always splitting, Big bangs would always be happening. Like that one, and that, and that, and......... ;)

You guys are all idiots, that are trying to sound smart. STOP!!! It's all God's creation. You will never understand it, because you puny humans are stupid and trying to justify everything. There are things that no matter how many years you try to solve, will never be solved. THE END!

The fact that a parallel universes location is measured by distance in this article makes me think they have no idea what they are dribbling on about, how can another universes location be measured by a unit of the distance dimension taken in this universe? measurement of the time dimension...maybe?...but distance????

Steven Gill is the exact reason that humanity has not advanced as far as it could be right now, all due to these ridiculous religious theories. Religion is the result of our own brains not understanding something, so we come up with come "greater being" that has made everything and is the supreme ruler. Many scientists (Albert Einstein, Laplace, and others) have only invoked religion at the stretch of their knowledge when they could not solve the problem. Guess what, after each of these religious premonitions another scientist or engineer came in after and solved the problem with no issues. For example, back in the 1500's all religious factions coalesced in an area near what is now Pakistan and was the center hub for intellectual advancement. Everyone worked together and threw aside their religious beliefs in search of knowledge. That is the place where numbers, modern algebra, calculus, as well as many other principles. Then a leader stepped in and told everyone that numbers are the work of the devil. Then the innovation stopped. Imagine if this momentum kept up, we would all have free energy by now as well as interstellar travel.

^^Meant to say jack lol.

Martin Tillier brings up the subject of gravity in his suggestion these theories are unsound. There is an ever growing belief among certain scientists that the comparatively weak force of gravity cannot account for many of the phenomena we see in our universe, and suggest that electricity is more likely to be the dominant force that holds everything in balance, and of course, magnetism.

This is an old article. Now, in 2017, parallel universes have been proved with not one, but two different versions of a series of physical experiments. You can read all about it in this press release that also has a link to the science paper as well as a video embedded that shows the experiments. -
