TIME WILL END IN FIVE BILLION YEARS, PHYSICISTS PREDICT
Our universe has existed for nearly 14 billion years, and the universe should continue to exist for billions of years more.
But according to a new paper, there's one theory for the origins of the universe that predicts time itself will end in just five billion years— around the time our sun is slated to die.
The prediction comes from the theory of eternal inflation, which says our universe is part of the multiverse. This vast structure is made up of an infinite number of universes, each of which can spawn an infinite number of daughter universes.
The problem with a multiverse is that anything that can happen will happen an infinite number of times, and that makes calculating probabilities—such as the odds that Earth-size planets are common—seemingly impossible.
