The particle-smashing Large Hadron Collider (LHC) in Cern, Switzerland, will restart next week and one of its major projects will be to search for tiny black holes, which could be gateways to parallel universes and new dimensions.
The idea that a parallel universe or many universes (multiverses) exist, has been around for a while. There is string theory and the "many-worlds" theory and variations upon these. But nobody has ever been able to carry out an experiment capable of successfully testing this.
However, a new proposal which postulates that tiny black holes connect us to other universes, has been put forward by Mir Faizal, and Mohammed M. Khalil of the University of Waterloo in Canada. Their study has been published in Physics Letters B and scientists at the LHC will now be testing their theory in practice.
