Hawking was bothered by the question of the multiverse theory for a number of years, having detailed his 'no boundary theory' back in 1983 alongside James Hartle. This described how the earth came into being through the Big Bang, but also predicted that the event would have been accompanied by numerous other 'Big Bangs', therefore creating the multiverse.
Carlos Frenk, who is a professor of Cosmology at the University of Durham, has argued that the work is exactly "what cosmology needed", stating that finding the evidence would completely change our perception of the cosmos. He also told the Sunday Times that the prospect of finding existence of another universe is "breathtaking" .
It is currently being reviewed by a leading scientific journal and may well prove the astrophysicist's most important scientific discovery, no small feat considering the remarkable body of work he has left behind.Explore more on these topics:
