“It is truly amazing to be looking, albeit on a microscopic scale, at the conditions and state of matter that existed at the dawn of time.”

Guido Tonelli -CERN's CMS Experiment

Could new data from CERN's LHC hint at the existence of a parallel universe? At a meeting of the European Physical Society in Grenoble, France, physicists -- including some from Caltech -- announced that the latest data from the Large Hadron Collider (LHC) might hint at the existence of the ever-elusive Higgs boson.

According to the Standard Model, the remarkably successful theory of how all the fundamental particles interact, the Higgs boson is responsible for endowing every other particle with mass. And as the last remaining particle pr edicted by the Standard Model yet to be detected, its discovery is one of the chief goals of the LHC, the most powerful particle accelerator on Earth and perhaps the most complex scientific endeavor ever attempted.

The LHC accelerates protons around an underground  ring almost five miles wide to nearly the speed of light, producing two proton beams that careen toward each other. Most of the protons just keep on going past each other, but a small fraction of them collide, creating other particles in the process. But these particles are fleeting, decaying into lighter particles before they can be detected. The challenge for physicists is to pick out hints of new, exotic physics from the flurry of newly minted particles. By sifting through the data, they hope to tease out signs that some of these particles are Higgs bosons.

The LHC is equipped with several detectors, but the ones that are the largest and are going after the Higgs are called ATLAS (A Toroidal LHC Apparatus) and the Compact Muon Solenoid (CMS); Caltech plays a prominent role in the latter. Both experiments recently reported what physicists are calling "excess events."

That is, the LHC appears to have created slightly more events than would be expected if the Higgs does not exist. The bump occurred in the region between 130 and 150 gigaelectron volts (GeV—a unit of energy that is also a unit of mass, via E = mc2, where the speed of light, c, is set to a value of one), which is the expected mass range of the Higgs.

But the data are not yet statistically significant enough to be called a definite signal, let alone a discovery of the Higgs particle, says Harvey Newman, professor of physics.

There are two possible explanations for these results, he says. The bump in the data could just be background events due to some unknown source or it could be the first signs of the Higgs. "One could speculate that it's an unusual statistical fluctuation," he says. "But I don't think so."

The LHC is now operating with 7 teraelectron volts (TeV, a thousand times higher than a GeV) of energy at the center of mass between the two proton beams, and may increase to 8 TeV next year (the maximum energy is 14 TeV, which will be reached by 2014).

Physicists will continue to ramp up the LHC, boosting it to higher energies and increasing the number of collisions to improve the chances of producing Higgs bosons. With several times more particle interactions, the physicists are continuing to close in on the Higgs, as well as other new particles and interactions. There's a chance that by the end of next year, they may determine, once and for all, whether the Higgs exists.

If it turns out that the Higgs does not exist, then physicists will have to do some serious rethinking about the Standard Model. "But even if the Higgs exists, the Standard Model still has fundamental problems," Newman says. For example, the theory is not self-consistent. "The most natural way to solve these problems," he says, "is with supersymmetry."

Evidence for supersymmetry, abbreviated SUSY ("soosie"), is also something that physicists had anticipated at the LHC. The theory proposes that each fundamental particle has a supersymmetric partner—for example, a quark's partner is called a "squark."

There are many versions of the theory, from simple toy models to subtler ones. So far, however, the LHC hasn't detected any signs of supersymmetry. "Many of the models we're excluding are toy models," says Maria Spiropulu, an associate professor of physics.

So even though people might be disappointed, it's way too early to rule out the theory. "Some people get depressed that SUSY is being excluded. But it's quite the opposite—we're confirming that nature is much more subtle than what the obvious thing would be."
What Exactly Is a Higgs Boson?

In 1964, a physicist named Peter Higgs proposed the existence of a field that permeates the whole universe. Just as a magnetic field interacts with iron filings, the so-called Higgs field, which permeates the vacuum between every particle in the universe, interacts with every fundamental particle. These interactions slow a particle as it moves through the field. Because an electron, for example, doesn't interact with the Higgs field that much, it can zip through the field with ease like a sleek anchovy swimming through the ocean, and, as a result, has little mass.

Particles like the top quark interact with the Higgs field a lot more strongly, however, so to them, the field is more like an ocean of molasses than of water. The top quark is thus heavy and sluggish, weighing in at more than 300,000 times the mass of an electron. In physics, every field has an associated particle; the electromagnetic field is associated with the photon, for instance. For the Higgs field, the associated particle is the Higgs boson. By interacting with itself, it's responsible for its own mass.

Beyond finding the Higgs, one of the most fascinating discoveries of our new century may be imminent if the Large Hadron Collider produces nano-blackholes. 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.

im 12 this is confusing can someone xplain to me in simpler terms

I don't quite understand why this would be so important. It would be an enormous achievement and well worth it but it seems like it would be a milestone not a paradigm shift like relativity or something similar.

@What

Google "Through the wormhole" and watch the two seasons :)

Untill we will have some proves, and not one but many identical ones, so that we can set a Solid Big Truth, all we read now is pure Science Fiction. We need to wait a couple years for that (if we`re lucky).

What they're looking for they will not find, because as Jerry Wheatley one of the most brilliant minds of our time, author of "The Nature of Consciousness : The Structure of Reality: Theory of Everything Equation Revealed : Scientific Verification and Proof of Logic God Is," has declared:

"The Higgs boson doesn't exist. It doesn't exhibit mass. It is the 'particle' that gives rise to particles exhibiting mass: those that do exist. The Higgs is not part of reality. It is what generates reality. The Higgs is more properly associated with 'potentiality' rather than reality. It turns out potentiality is more real than 'reality.' It is potentiality that underlies quantum nonseparability. Therefore, reality is a projection of potentiality and hence is illusory."

"It isn't a particle. It is space itself [the Whole of Reality] and reflects the continuum as understood mathematically. Extended space exhibits nonzero characteristics."

I don't get it, I'm still trying to figure out how they got the caramel in the Caramilk bar...

If you asked me, from what I've heard from experts such as Tom Horn and Steven Quayle, the LHC Collider is just an excuse, a COVER STORY, for secret experiments on how to tear open the time-space barrier to other dimensions and to allow demonic entities to enter our worlds and cause chaos and pandemonium.....I concur with Steve Savage that there is NO such thing as the Higgs Bosum particle, just as there is NO tooth fairy.....

Aren't 'dark energy' and 'dark matter' opposites in their effect? Dark matter gravitationally tightens galaxies, 'dark energy' is anti-gravitational, expanding space-time at an increasing rate... no?
So while a close-by parallel universe leaking gravity might explain 'dark matter', I don't see the relation to the phenomenon we refer to as 'dark energy'.

Why only 1 universe as a paralell - why not infinite? Infinity being the truest concept of divine understanding...

I've been wondering. Is there such a thing as the Higgs?
Sure there might be. But it'll probably turn out not to be like they expected.

Is there a thing such as the smallest particle? In ancient Greece it was thought that atoms where the smallest thing in the world. We know now that they're not. It wouldn't surprise me if what we find out is that there's nothing smallest. No matter how small you can always find something smaller. Probably the universe is fractal like in the way it's build up. The opposite we might find is also true. No matter how large scale you look at there's always something even bigger. For now the biggest thing we know is the universe but if we can look outside our own dimension we'll probably find that our universe is only a Higgs particle in something mind blowing bigger and perhaps on it's way down a black hole in that universe (hence the acceleration).

How can this be? "There's no spoon"! But not meant that way. Particles etc. are property of space - nothing more than disturbed space which when several eons has passed will smooth out and material as we know it in our universe will cease to exist. Waiting for the next disturbance to happen a google of eons later and once again bring life to our universe.
