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

What if another version of you exists in a parallel universe, influencing your life without you even knowing it? A new quantum physics theory suggests it’s possible.

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 ...

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

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 ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Scientists have found “strange quarks” that originated as virtual particles that sprang from nothing Quantum physics paints a strange picture of the world, one filled with spooky connections, ...

Scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory have uncovered experimental evidence that ...

Interest in the multiverse theory, suggesting that our universe is just one of many, spiked following the release of the movie "Everything Everywhere All At Once." The film follows Evelyn Wang on her ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along ...

Wormholes are often imagined as tunnels through space or time — shortcuts across the universe. But this image rests on a misunderstanding of work by physicists Albert Einstein and Nathan Rosen. In ...
