If true, the idea would blow past one of physics’ most sacred limits: that parallel versions of reality can never talk to ...

Cosmology and quantum physics both offer tantalizing possibilities that we inhabit just one reality among many. But testing that idea is challenging.

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 ...

Google’s new quantum computer chip, named Willow, is able to run computations so complex that it would supposedly take the world’s fastest supercomputers the entire lifetime of the universe to ...

The multiverse suggests that our universe may not be unique, but just one of countless others existing beyond our observable reality. Some versions arise naturally from inflation theory and quantum ...

From your morning coffee to the road leading to your office and all other things and people you experience in your everyday life are all part of the classical world. This world is governed by the ...

Add Yahoo as a preferred source to see more of our stories on Google. While parallel universes are a staple of science fiction, there are some real scientific theories to support them. But if parallel ...

It’s one quantum leap for mankind. Parallel dimensions are no longer restricted to Marvel flicks. Google’s cutting-edge quantum chip Willow has prompted discussions among scientists about the ...

To reach this conclusion, the researchers examined the most basic form of entanglement between identical particles using the concept of nonlocality introduced by physicist John Bell. While ...

At long last, a unified theory combining gravity with the other fundamental forces—electromagnetism and the strong and weak nuclear forces—is within reach. Bringing gravity into the fold has been the ...

A century since Werner Heisenberg changed the course of physics, five of the world’s leading physicists examine the greatest achievements of quantum mechanics and look forward to the next 100 years, ...
