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.
Concerning matter, we have been all wrong. What we have called matter is energy, whose vibration has been so lowered as to be perceptible to the senses. There is no matter.

GENEVA (Reuters) - CERN's Large Hadron Collider (LHC) is gearing up to resume full-speed particle collisions next month aimed at resolving key mysteries of the universe, scientists and engineers at the research center said on Monday.
They reported that the giant subterranean machine was in fine shape after a 10-week shutdown and that particle beams circulating in it again since the weekend would be boosted to top speed by the end of the day.
"Everything is going very well indeed. Progress has been extremely rapid since we switched the LHC on again late on Saturday," Mike Lamont, head of operations at the LHC control room just outside Geneva, told Reuters.
The LHC was closed down on December 6 for technical checks of its hugely complex apparatus after eight months of operations.
"We hope to ramp up to full beam within the next few hours," said Lamont, referring to the highest energy achieved so far in the machine -- 3.5 tera electron volts, or TeV -- since it first went into operation on March 31 last year.
"Our analyst teams are preparing to work on 'new physics' data that will start flowing once collisions start up again in about three weeks," said Oliver Buchmueller, team leader on the LHC's CMS detector, one of the project's four major experiments.
NEW PHYSICS
New Physics, the motto of the LHC, refers to knowledge that will take research beyond the "Standard Model" of how the universe works that emerged from the work of Albert Einstein and his 1905 Theory of Special Relativity.
"We will be focusing this year on super-symmetry, extra dimensions, how black holes are produced, and the Higgs boson. We expect some first results by the summer," said Buchmueller.
Super-symmetry, dubbed SUSY, is a theory allowing for the existence of unseen doubles of elementary particles and if proven correct would explain the mystery of dark matter, believed to make up nearly a quarter of the known universe.
It could also help back up the string theory concept which provides for extra dimensions other than the known four -- length, breadth, depth and time -- and for the existence of parallel universes.
Black holes are collapsed stars, observed in many galaxies in the known universe, around which the force of gravity is so strong that nothing, not even light, can escape. But scientists want to know more about how they come about.
The Higgs boson has been posited for over 30 years as the agent that gives mass to matter, and made formation of the universe possible immediately after the Big Bang 13.7 billion years ago. But proof that it exists has still to be found.
Information on all these is expected to emerge as CERN -- the 21-nation European Organization for Nuclear Research -- pursues its simulations of the Big Bang with billions of high-energy collisions in the LHC.

Detection of mini black holes at the LHC could indicate parallel universes in extra dimensions
(Phys.org)—The possibility that other universes exist beyond our own universe is tantalizing, but seems nearly impossible to test. Now a group of physicists has suggested that the Large Hadron Collider (LHC), the largest particle collider in the world, may be able to uncover the existence of parallel universes, should they exist.
In a new paper published in Physics Letters B, Ahmed Farag Ali, Mir Faizal, and Mohammed M. Khalil explain that the key to finding parallel universes may come from detecting miniature black holes at a certain energy level. The detection of the mini black holes would indicate the existence of extra dimensions, which would support string theory and related models that predict the existence of extra dimensions as well as parallel universes.
"Normally, when people think of the multiverse, they think of the many-worlds interpretation of quantum mechanics, where every possibility is actualized," Faizal told Phys.org. "This cannot be tested and so it is philosophy and not science. This is not what we mean by parallel universes. What we mean is real universes in extra dimensions. As gravity can flow out of our universe into the extra dimensions, such a model can be tested by the detection of mini black holes at the LHC. We have calculated the energy at which we expect to detect these mini black holes in gravity's rainbow [a new theory]. If we do detect mini black holes at this energy, then we will know that both gravity's rainbow and extra dimensions are correct."
The search continues
In some ways, this idea is not new. The LHC has already been trying to detect mini black holes, but has come up empty-handed. This is what would be expected if there are only four dimensions, since the energy required to produce black holes in four dimensions would be much larger (1019 GeV) than the energy that can be achieved at the LHC (14 TeV).
However, if extra dimensions do exist, it is thought that they would lower the energy required to produce black holes to levels that that the LHC can achieve. As Faizal explained, this happens because the gravity in our universe may somehow flow into the extra dimensions. As the LHC has so far not detected mini black holes, it seems that extra dimensions do not exist, at least not at the energy scale that was tested. By extension, the results do not support string theory or parallel universes, either.
In their paper, Ali, Faizal, and Khalil offer a different interpretation for why mini black holes have not been detected at the LHC. They suggest that the current model of gravity that was used to predict the required energy level for black hole production is not quite accurate because it does not account for quantum effects.
According to Einstein's general theory of relativity, gravity can be thought of as the curvature of space and time. However, here the scientists point out that this geometry of space and time responsible for gravity gets deformed at the Planck scale. They have used the new theory of gravity's rainbow to account for this modification of the geometry of space and time near the Planck scale, where the mini black holes are predicted to exist.
Using gravity's rainbow, the scientists found that a little bit more energy is required to produce mini black holes at the LHC than previously thought. So far, the LHC has searched for mini black holes at energy levels below 5.3 TeV. According to gravity's rainbow, this energy is too low. Instead, the model predicts that black holes may form at energy levels of at least 9.5 TeV in six dimensions and 11.9 TeV in 10 dimensions. Since the LHC is designed to reach 14 TeV in future runs, these predicted energy requirements for black hole production should be accessible.
Many interpretations
If mini black holes are detected at the LHC, then it would arguably support several ideas: parallel universes, extra dimensions, string theory, and gravity's rainbow—with these last two having implications for a theory of quantum gravity. Most obviously, a positive result would support the existence of mini black holes themselves.
"If mini black holes are detected at the LHC at the predicted energies, not only will it prove the existence of extra dimensions and by extension parallel universes, but it will also solve the famous information paradox in black holes," Ali said. Solving the paradox is possible because, in the gravity's rainbow model, mini black holes have a minimum radius below which they cannot shrink.
However, if black holes are not detected, the scientists will need to reexamine their understanding of these ideas.
"If black holes are not detected at the predicted energy levels, this would mean one of three possibilities," Khalil explained. "One, extra dimensions do not exist. Two, they exist, but they are smaller than expected. Or three, the parameters of gravity's rainbow need to be modified."
In the world of theoretical physics, there is never just one interpretation, and the same goes for this issue. Remo Garattini, Professor of Physics at the University of Bergamo, has used gravity's rainbow in his work on regulating ultraviolet divergences, which have plagued models of quantum gravity. Although he is sympathetic to many of the ideas in gravity's rainbow, he points out that the current paper relies on only one proposal, which uses an equation that does not eliminate divergences.
"I think that the paper is interesting, but we have to be careful to extrapolate global results using only one proposal for the rainbow's functions," Garattini said.
Along these lines, Joao Magueijo, Professor of Physics at Imperial College London, cautions that the details of the theory that will either make it or break it. And at this early stage, it's difficult to tell what these details should be.
"The work is interesting, but like many other applications of rainbow gravity, it does depend crucially on the chosen free functions of the theory," Magueijo said.
"Still, I think this work could be a valuable step in constraining those free functions."
