The universe is a strange, beautiful place—rich with possibilities and governed by the odd rules of quantum mechanics. One of the most mind-bending ideas from this realm is the many-worlds ...

Evidence of this quantum layer may be coming soon. Here’s what you’ll learn in this story: Physicists are still puzzling over ...

Could our universe be expanding then shrinking back into a tiny point, reliving a kind of big bang over and over again? Probably not, according to a mathematical analysis that argues that the laws of ...

It's a plot device beloved by science fiction: our entire universe might be a simulation running on some advanced ...

In 2022 three scientists won the Nobel Prize in Physics for proving something astonishing: the universe is not locally real. In other words, particles don’t have fixed properties until they are ...

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 wouldn ...

It’s one of those questions that creeps into your mind late at night: what if there’s another version of you […] ...

In the strange world of quantum mechanics, objects can exist in several states at once. This concept, called superposition, is one of the most puzzling features of quantum theory. A particle, for ...

Modern multiverse fiction incorporates real physics equations and string theory principles rather than relying on pure ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...
