Detecting other universes: Hawking's final paper

Quote:

A final theory explaining how mankind might detect parallel universes was completed by Stephen Hawking shortly before he died, it has emerged. Colleagues have revealed the renowned theoretical physicist’s final academic work was to set out the groundbreaking mathematics needed for a spacecraft to find traces of multiple big bangs. Currently being reviewed by a leading scientific journal, the paper, named A Smooth Exit from Eternal Inflation, may turn out to be Hawking’s most important scientific legacy. [...] The new paper seeks to resolve an issue thrown up by Hawking’s 1983 “no-boundary” theory which described how the universe burst into existence with the big bang. According to that account, the universe instantaneously expanded from a tiny point into a prototype of what we live in today, a process known as inflation. But the theory also predicted an infinite number of big bangs, each creating their own universe, a “multiverse”, which presented a mathematical paradox because it is seemingly impossible to measure. Carlos Frenk, professor of cosmology at Durham University, told The Sunday Times: The intriguing idea in Hawking’s paper is that [the multiverse] left its imprint on the background radiation permeating our universe and we could measure it with a detector on a spaceship..

Sounds intriguing. I look forward to learning more when the paper is published
