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.

What lies beyond the universe? For centuries, scientists have pondered this question, and recent groundbreaking discoveries may hold the answer. Using state-of-the-art quantum computers at CERN, ...

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 ...

That our universe is expanding is in wide agreement, though how exactly that process happens is not as well understood. Scientists believe that an elusive substance called "dark energy" is ...

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, ...

Parallel universes crop up in two places in physical theories. One is in our conception of inflation, the theory of the extremely early universe.In those tumultuous times, many universes may have ...

The idea of multiple universes coexisting has intrigued scientists, philosophers, and storytellers for decades. Now, thanks to advancements in quantum mechanics, the many-worlds interpretation ...

To find evidence of these multiple universes, scientists look at the cosmic microwave background or the CMB. This is essentially the light left over from the Big Bang, and scientists believe that ...

This quantum entanglement is what gives us multiple universes! With entangled superposition, we cannot separate the cat from the box from the observer (us). We are all linked together.

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 ...

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 ...
