The idea of multiple universes, or a multiverse, is suggested by not just one, but numerous physics theories. Here are the top five ways additional universes could come about.

For now, plenty of questions remain unanswered — about multiple universes and the reality of our own, she said. "None of these can be proven — but they're fun to think about," Macdonald said.

While the latest study is by no means the first to propose the idea of multiple universes, it offers a mathematical model to show how merging with other, smaller universes might expand our universe.

The concept of multiple universes goes back to the 6th century, when pre-Socratic Greek philosopher Anaximander suggested the idea of infinite worlds for the first time. Yet multiverse ideas ...

By contrast, the multiple universes predicted by some theories of cosmic inflation are what Tegmark calls a Level II multiverse, where fundamental physics can be different across the different ...

The idea of multiple universes actually dates back to the Ancient Greeks like Democritus, or even earlier to pre-Socratic philosopher Anaximander and his idea of infinite worlds, ...

Google Quantum AI founder Hartmut Neven wrote in his blog post that this chip was so mind-boggling fast that it must have borrowed computational power from other universes.. Ergo the chip’s ...

But, as Paul Halpern shows in “The Allure of the Multiverse: Extra Dimensions, Other Worlds, and Parallel Universes,” the positing of multiple universes often aims for a different ...

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 ...

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 ...
