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. It also claims that the footprint of this radiation should be "detectable using a deep space probe" equipped with needed sensors.
In the "no boundary theory", the duo had described how our Earth exploded into existence during Big Bang.
His most recent work was an update to his paper titled A Smooth Exit from Eternal Inflation in which he attempts explain how the existence of parallel universes would mesh with our current understanding of physics.
Thomas Hertog, professor for theoretical psychics at KU Leuven University in Belgium, said Hawking finished the research from his deathbed, The Sunday Sun reported. We all remember when he told Homer Simpson "Your theory of the universe in the form of a donut is "intriguing".
Professor Hawking died on March 14th at the age of 76, having been diagnosed at 21 with a type of motor neurone disease, amyotrophic lateral sclerosis (ALS), and given two years to live. It also predicted a multiverse which means the phenomenon was accompanied by several other "Big Bangs" creating separate universes.
He also told the Sunday Times that the prospect of finding existence of another universe is "breathtaking".
Some researchers believe this recent paper could be a breakthrough, as it's the first theory that could be tested.
The idea, notes Hertog, was to "transform the idea of a multiverse into a testable scientific framework". It suggests that the universe we know will end when the stars run out of energy.
Scientists and trustee of Stephen Hawking Foundation have dismissed the science minister's claim as baseless, says a British newspaper. Hawking will not be, simply because the prize is not awarded posthumously. Canada's Perimeter Institute director Neil Turok, one of Hawking's friends, said he remained puzzled as to why he found this picture interesting.
