The study, which is being revised for publication, deals with parallel universes. Colleagues of the deceased scientist explained that, if the calculations of Hawking are correct, could lay the foundations that demonstrate the existence of other universes that coexist with ours.
Hawking worked on the idea that the big bang was not only the moment of the beginning of our universe, but it was also the starting point of a multiverse in which infinite universes expand in a parallel way to ours.
The physicist believed that the key to detecting this expansion may lie in the same cosmic microwave background radiation. The study, in fact, the method used to detect this multiple big bang by means of a sensor installed in a space probe. Carlos Frenk, professor of cosmology at the University of Durham explains in an interview to The Sunday Times: Hawking's latest work offers the incredible perspective that we can find evidence of the existence of other universes.
To be right, this latest work would also prove somewhat less flattering, that the universes generated in the Big Bang, including ours will eventually disappear when the stars exhaust all available energy. Hawking's colleagues believe that his latest contribution to science could have earned him the Nobel prize that eluded him throughout his life.
