Quantum entanglement happens when two particles become interconnected and share a single state. Scientists have measured how ...

Quantum mechanics has always carried a quiet tension. At its core, the theory allows particles to exist in many states at ...

Quantum physics overturned classical ideas by showing that matter behaves very differently at the ...

A study by physicists affiliated with the Foundational Questions Institute (FQxI) found that time ...

Can two versions of reality exist at the same time? Physicists say they can — at the quantum level, that is. Featuring new ...

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

In an effort to bring together the domains of gravity and quantum theory, Albert Einstein and Nathan Rosen proposed a ...

Wormholes are often imagined as tunnels through space or time—shortcuts across the universe. But this image rests on a ...

One of the discoveries that fundamentally distinguished the emerging field of quantum physics from classical physics was the ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...
