Stephen Hawking is still advancing science from the grave.
An updated theory submitted 10 days before his death provides evidence for the presence of a “multiverse” that is less complicated than we thought.
As the story goes, our universe began with the Big Bang. During a period of rapid expansion (known as inflation), the cosmos swelled from subatomic to golf ball-sized almost instantaneously—possibly creating various pocket worlds, i.e. the multiverse.
New research, however, suggests that 53 Earths occupying the same space are separated because they vibrate at different frequencies those universes may not be that different from our own.
