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

Measuring the world precisely is much harder than it sounds. At very small scales, ...

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

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

Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a ...

For more than a century, modern physics has rested on two towering frameworks that do not quite agree with each other.

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

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

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 ...

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

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