The detection of miniature black holes by the Cern large hadron collider might prove the existence of a parallel universe and show that the Big Bang did not happen. The giant particle accelerator, which will be restarted this week, last year found the Higgs boson, called by some "the God Particle", which is thought to give other sub-atomic particles, and matter, their mass.Now scientists at the Cern installation in Switzerland believe they might find miniature black holes, which, some theories posit, would reveal the existence of a parallel universe.And if the holes are found at a certain energy, it could prove the controversial theory of rainbow gravity, which suggests that the universe stretches back in time infinitely and that there is no singular point at which it started - and so no Big Bang.The rainbow gravity theory was postulated to reconcile Einstein's theory of general relativity, which deals with very large objects, up to cosmic scale, and quantum mechanics, applicable at sub-atomic scale.It takes its name from a suggestion that gravity affects different wavelengths of light - in other words, colours of light - differently.The huge amounts of energy needed to generate rainbow gravity mean that if the theory is true the early universe would have been very different to that described by older theories. If you were to go back in time the universe, according to the rainbow theory, would approach infinite density but never quite reach it.The effect of rainbow gravity is small for objects comparable in mass to the Earth but it is significant and measurable for black holes. It could be detected by the large hadron collider if it created black holes."We have calculated the energy at which we would expect to detect mini black holes according to the rainbow gravity theory."If we do detect them at this energy we will know that the theories positing rainbow gravity and extra dimensions are correct," Dr Mir Faizal told Phys.org.The second run of the collider will begin this week and the beams are expected to go fully around the 27km circular accelerator on Wednesday for the first time since it was shut down in early 2013 for upgrading.When it is fired up it will smash protons together at nearly double the energy that was available to find the Higgs boson.Rolf Heuer, director-general of Cern, said the switch-on would create "a new era for physics" that could shed light on the nature of dark matter, dark energy and super-symmetry."I want to see the first light in the dark universe. If that happens, then nature has been kind to me."Scientists believe they could find the first proof of alternative realities that exist outside our own universe."Just as a stack of many sheets of paper, which are virtually two-dimensional objects [breadth and length] can exist in a third dimension [height], parallel universes can exist in higher dimensions," said Faizal."When people think of the multiverse they think of the many-worlds interpretation of quantum mechanics, in which every possibility is actualised in its own universe."This cannot be tested and so is philosophy, not science."This is not what we mean here by 'parallel universes' - we mean real universes in extra dimensions."Frances Saunders, president of the Institute of Physics, in the UK, said, "These higher energies [could] give us greater insight into the 95% of the universe that is composed of dark matter and dark energy." - ©The Daily Telegraph and Staff reporter..
