By the end of this century, says astrophysicist Martin Rees, we should be able to ask whether or not we live in a multiverse, and how much variety of the laws of physics its constituent ‘universes’ display. The answer to this question, says Rees, “will determine how we should interpret the ‘biofriendly’ universe in which we live (sharing it with any aliens with whom we might one day make contact).”
China is building a particle accelerator that will be twice as large and seven times as powerful as CERN’s LHC and astrophysicist, Martin Rees, famous for his contributions to black hole formation to extragalactic radio sources and the evolution of the universe, thinks that there’s a chance the colliders could cause a “catastrophe that engulfs space itself”.
