Prof Stephen Hawking’s final analysis paper suggests that our Universe might be one of many similar to our own.
The theory resolves a cosmic paradoxon of the late physicist’s own producing.
It also points a means forward for astronomers to find proof of the existence of parallel universes.
The study was submitted to the Journal associated with High-Energy Physics week before Prof Hawking died.
In the 1980s, the Cambridge scientist, along with US physicist Adam Hartle developed a new idea in regards to the beginning of the Universe.
This resolved a difficulty with Einstein’s theory that suggested that the World began nearly 14 billion in years past but said nothing about how this began.
Instead, the particular Hartle-Hawking idea used a different concept called quantum mechanics to explain the way the Universe arose from nothingness.
The idea tied up one reduce end but created another — an infinite number some might say.
As physicists analysed the idea it emerged that it transported with it the implication that the Large Bang would create not just 1 universe – but an endless provide.
Some, according to the Hartle-Hawking theory, will be very like our own, perhaps have got Earth-like planets, societies, even people similar to the ones in our Universe.
Other universes will be subtly different – perhaps along with Earth-like planets where dinosaurs are not wiped out. And there would be universes totally unlike our own, with no Earths, probably no stars and galaxies and various laws of physics.
It sounds far-fetched, but the equations with this theory make such scenarios in theory possible.
A crisis comes up because if there are infinite types of universes with infinite variations in their laws and regulations of physics then the theory are unable to predict what kind of universe we should discover ourselves in.
Prof Hawking joined forces with Prof Thomas Hertog at KU Leuven in Belgium, who is funded from the European Research Council to try to solve this paradox.
“Neither Stephen nor I had been happy with that scenario, ” he or she told BBC News.
“It suggests that the multiverse surfaced randomly and that we can’t state very much more about that. We believed to each other: ‘Maybe we have to live with it’. But we didn’t want to quit. ”
Prof Hawking’s final paper is the fruit associated with 20 years’ work with Prof Hertog.
It has resolved the puzzle by drawing on brand new mathematical techniques developed to study an additional esoteric branch of physics known as string theory.
These techniques enable researchers to see physics theories in a different way. And the story assessment of the Hartle-Hawking theory within the new paper has restored purchase to a hitherto chaotic multiverse.
The study, funded by the Western european Research Council, indicates that there can simply be universes that have the same laws and regulations of physics as our own.
That conjecture means that the Universe is typical and so findings we make from our viewpoint is going to be meaningful in developing our tips of how other universes emerged.
Mind-bending as these ideas are usually, they will be of real help to physicists as they develop a more complete concept of how the Universe came into being, based on Prof Hertog.
“We are really talking about the most fundamental type of theory you can imagine, to provide a deeper knowledge of where our theories come from and exactly how they arise. ”
“The laws of physics that we test in our labs failed to exist forever. They crystallised following the Big Bang when the universe extended and cooled. The kind of laws that will emerge depends very much on the bodily conditions at the Big Bang. Simply by studying these we aim to obtain a deeper understanding of where our bodily theories come from, how they arise, plus whether they are unique. ”
One tantalising implication from the findings, according to Prof Hertog, is it might help researchers detect the presence of additional universes by studying the micro wave radiation left over from the Big Beat – though he says that he will not think it will be possible to hop in one universe to another.
