CERN Scientists Seek Hidden Dimensions Beyond the Observable Universe

Post-2505-1180127849 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 into high gear, they are talking increasingly of the "New Physics" on the horizon that could totally change current views of the universe and how it works.

"Parallel universes, unknown forms of matter, extra dimensions… These are not the stuff of cheap science fiction but very concrete physics theories that scientists are trying to confirm with the LHC and other experiments," according to the  center's Theory Group, which mulls over what could be out there beyond the reach of any telescope, wrote in the CERN Bulletin this month.

At full throttle, the LHC could provide scientists with new insights into the nature of mass, dark matter and the origins of the universe. But many of them hope that instead of confirming string theory, dark energy, the Higgs-Boson, etc. — something entirely unexpected will emerge from the CERN-run experiment, for example the detection of certain types of supersymmetric particles, that could be seen as what physicist Michio Kaku calls, “signals from the 11th dimension.”

The detection of certain types of supersymmetric particles, aka sparticles, could be seen as what physicist Michio Kaku calls, “signals from the 11th dimension.”

Several of the world's leading cosmologists, Michio Kaku a prime example, 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 bu 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.

Many of the multiple universe proponents are awaiting eagerly for the Large Hadron Collider in Geneva to smash the basic components of the universe together at near the speed of light along a 84-kilometer-long underground racetrack, causing an awesomely high energy reaction similar to the temperatures involved at the Big Bang and spew out the secrets to the cosmos. More exciting than the discovery of Higgs Boson, who's function is giving mass to the particles of matter, could be the possible creation of tiny, particle-sized black holes. Real data from these experiments will rewrite the theorists' "Guide to the Quantum Universe."

According to current physics these nano black holes could not be created at the energy levels the LHC is capable of producing. They could only be created if a parallel universe act.

As particles are collided in the vast underground LHC complex at increasingly high energies, what the Bulletin article referred to informally as the "universe's extra bits" — if they do exist as predicted — should be brought into computerized, if ephemeral, view, the theorists say.

Optimism among the hundreds of scientists working at CERN — in the foothills of the Jura mountains along the border of France and Switzerland — has grown as the initially troubled $10 billion experiment hit its targets this year.

By mid-October, Director-General Rolf Heuer told staff last weekend, protons were being collided along the 27-km (16.8 mile) subterranean ring at the rate of 5 million a second — two weeks earlier than the target date for that total.

By next year, collisions will be occurring — if all continues to go well — at a rate producing what physicists call one "inverse femtobarn," best described as a colossal amount, of information for analysts to ponder.

The head-on collisions, at all but the speed of light, recreate what happened a tiny fraction of a second after the primeval "Big Bang" 13.7 billion years ago which brought the known universe and everything in it into being.
