The no-boundary theory describes how the earth came to the plain of existence during the Big Bang.
With deep space probes using the right sensors that measure background radiation accurately, it is possible to find parallel universes, claims Hawking in the study. Hertog, a physics professor at KU Leuven University in Belgium, told the Sunday Times that he got final approval to submit the paper during a recent in-person meeting with Hawking. It also theorizes about the end of the universe, saying that it will end as the stars run out of energy.
The paper, called A Smooth Exit from Eternal Inflation, will be published in a yet-to-be-named scientific journal once it's reviewed. The report claims that some scientists believe that Hawking's ideas could be ground-breaking for cosmology because it is the first testable theory.
Herzog is certain Hawking would have taken home the award for contributions to the advancement of science, telling the Sunday Times: "He would have won it".
The paper, co-written with James Hartle in 1983, led to the concept of the Hartle-Hawking state: that the primal universe prior to the Big Bang was a singularity in both space and time - and said universe has no beginning.
The theory, written by the two professors, also predicted a multiverse, meaning the phenomenon was accompanied by a number of other "Big Bangs" creating separate universes. Thomas Hertog expressed his sadness with the fact that Hawking wouldn't receive a Nobel due to the many reasons aforementioned. However, the duo has worked out ways to actually prove that there are indeed ways to scientifically test for other realities around us.
Frenk went on to say that if any evidence of other universes could be found, it would completely change how we see our universe. This is slightly different from Stephen's previous theory, which supposed that black holes would consume the universe.
