Mini Black Holes in the LHC Can Confirm Existence of Parallel Universes

A team of scientists has discussed the Many-Worlds Hypothesis (MWH) in a paper available on the journal Physics Letters B with a particular emphasis on the possibility of the Large Hadron Collider (LHC) – the largest particle collider on Earth – detecting mini black holes. The researchers put forward that the LHC identifying the minute black holes might constitute the test for the existence of other universes beyond ours.

The detection of the small black holes in question would serve as test to show the occurrence of extra dimensions that would support the String Theory and other hypotheses that speak of extra dimensions and parallel universes.

Commenting on the MWH, one of the authors, Professor Mir Faizal from the University of Waterloo, said in a statement to Phys.org:

“Normally, when people think of the multiverse, they think of the many-worlds interpretation of quantum mechanics, where every possibility is actualized. 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,” says Faizal. “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 LHC is said to have attempted to detect mini black holes already – it has failed so far. This would be the case if there are only 4 dimensions because the energy needed for the formation of black holes in 4 dimensions would be too large – around 1019 GeV – compared to what can be attained by the LHC, which is 14 TeV only.

But, the extra dimensions – if they exist, that is – would require less energy for the creation of black holes. Interestingly, this level of energy would be achievable by the LHC. Faizal explained that the gravity in our own universe might flow into other dimensions, hence making it possible.

However, if the LHC has not detected any mini black hole, it will mean that no extra dimension exists at tested energy scales. It is therefore said that the string theory and parallel universes are not supported by the results.

On the other hand, the researchers of the new paper provide new insight as to why the LHC has not yet detected the mini black holes. They explain that the current model of gravity used to forecast the energy levels for black hole formation is not accurate because it does not include quantum effects. They argue that the geometry of space and time responsible for gravity as per the general theory of relativity is distorted at the Planck scale. The scientists have made use of the new theory of gravity’s rainbow to explain this deformation. Using this, they found that a little bit more energy is needed for the creation of mini black holes at the LHC. According to gravity’s rainbow, the energy levels at which the LHC has searched for the black holes so far have been too low (below 5.3 TeV). Rather, the black holes might be forming at energy levels of at least 9.5 TeV in 6 dimensions and 11.9 TeV in 10 dimensions.

“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,” said one of the authors.
