We’ve covered Stephen Hawking’s final theory before, relating to the multiverse and the dazzling postulate that there were infinite Big Bangs, one right after the other, and that we exist in a slowed-down universe which allowed for solar systems, stars, and galaxies to form.
Hawking’s theory, co-authored with physicist Thomas Hertog of KU Leuven University in Belgium, posits that we can obtain quantifiable data that must be collected via space probe in order to be proven correct.
Says Hertog, “We wanted to transform the idea of a multiverse into a testable scientific framework.”
And that is what the paper is based on: Quantifying the background radiation from the beginning of time, which—if their theory is correct—should be measurable.
Basically, the theory holds that after the Big Bang, the universe expanded in what’s known as exponential inflation but some “bubbles” of that space stopped inflating or slowed down enough for stars and galaxies to form.
“The usual theory of eternal inflation predicts that globally our universe is like an infinite fractal, with a mosaic of different pocket universes, separated by an inflating ocean,” Hawking explained.

“The local laws of physics and chemistry can differ from one pocket universe to another, which together would form a multiverse. But I have never been a fan of the multiverse. If the scale of different universes in the multiverse is large or infinite the theory can’t be tested.”
And after trying hard to understand all of this, I think I’m going to pop a strong ibuprofen.
Here’s Hertog himself, explaining it as best he can in 22 minutes.
