Ergo the chip’s performance indicates that parallel universes exist and “we live in a multiverse.” Here’s the passage: Willow’s performance on this benchmark is astonishing: It performed ...

While parallel universes are a staple of science fiction, there are some real scientific theories to support them. But if parallel universes do exist, could we ever travel to them? It certainly ...

However, under the “many worlds” interpretation, which Hugh Everett came up with in his 1957 Princeton doctoral dissertation, “every outcome comes true, but in a different universe ...
