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."

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.

"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."
