‘Hawking’s final research paper supports existence of multiverse’


The latest research work by Stephen Hawking suggests that the universe may be one of many similar to ours, solving a cosmic paradox of the creation of the late British physicist. The document presented to the Journal of High Energy Physics, 10 days before Hawking died on March 14, also points out a way for astronomers to find evidence of the existence of parallel universes. In the 1980s, Hawking, along with American physicist James Hartle, developed a new idea about the beginning of the universe, BBC News reported.

This solved a difficulty with Einstein’s theory that suggested that the universe began almost 14 billion years ago, but did not say anything about how it started. The idea of ​​Hartle-Hawking used a theory called quantum mechanics to explain how the universe came from nothing. While the scientists analyzed the idea, it carried with it the implication that the Big Bang would create not only a universe, but an infinite supply. Some, according to the theory, would be very similar to our own universe, while others would be subtly different.

Hawking collaborated with Thomas Hertog, a professor at KU Leuven in Belgium, to try to solve this paradox. “Neither Stephen nor I were happy with that scenario,” Hertog said. The last work of Hawking solved the riddle based on new mathematical techniques developed to study another branch of physics called string theory. The new evaluation of the Hartle-Hawking theory in the last document has restored order to a hitherto chaotic multiverse.

The analysis suggests that there can only be universes that have the same laws of physics as ours, according to the document. According to Hertog, these ideas can be of great help to physicists as they develop a more complete theory of how the universe originated.
