Stephen Hawking submitted a final scientific paper 2 weeks before he died — and it could lead to the discovery of a parallel universe

  • Stephen Hawking is named as coauthor on a paper submitted March 4 – 10 days before he died.
  • It sets out a way of testing whether other universes are real.
  • Its mathematical theories could be tested with a deep-space probe.

Stephen Hawking submitted his final scientific paper just a week and a half before he died, and it lays the theoretical groundwork for discovering a parallel universe.

Hawking, who died Wednesday at 76, was coauthor to a mathematical paper that seeks proof of the “multiverse” theory, which posits the existence of many universes other than our own.

The paper, called “A Smooth Exit from Eternal Inflation,” had its latest revisions approved March 4, 10 days before Hawking’s death.

According to the Sunday Times newspaper, the paper is due to be published by an unnamed “leading journal” after a review is complete., the Cornell University website that tracks scientific papers before they are published, has a record of the paper including the March 2018 update.

According to The Sunday Times, the paper sets out the mathematics necessary for a deep-space probe to collect evidence that might prove that other universes exist.

The highly theoretical work posits that evidence of the multiverse should be measurable in background radiation dating to the beginning of time. This in turn could be measured by a deep-space probe with the right sensors.

Thomas Hertog, a physics professor who coauthored the paper with Hawking, said the paper aimed “to transform the idea of a multiverse into a testable scientific framework.”

Hertog, who works at KU Leuven University in Belgium, told The Sunday Times he met with Hawking in person to get final approval before submitting the paper.

The newspaper said that if such proof were ever found, it would make the scientists behind it likely candidates for a Nobel Prize.

However, since Nobel Prizes cannot be awarded posthumously, Hawking would be ineligible to receive it.
