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 ...

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 ...

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 ...

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 ...

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 ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other. Quantum theory governs particles and fields, while Einstein’s gravity describes ...

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 ...
