Theoretically, the LHC (Large Hadron Collider), the biggest particle collider on Earth, could possibly unlock and discover parallel universes. The key to finding out if something like this exists is explained in a published paper called Physics Letters B, written by Ahmed Farag Ali, Mir Faizal, and Mohammed M. Khalil. The paper outlines the theory that, if we can detect mini black holes, we can find the existence of other dimensions. This would also prove string theory and other theories that support extra dimensions. In order for the LHC to detect mini black holes, the energy level would have to be much higher than what is currently being tested in four dimensions. But if (and when) we can finally detect mini black holes here on Earth, we would find proof that other dimensions do exist. According to the paper:
[blockquote]“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.”[/blockquote]
