"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

A radical theory that consistently unifies gravity and quantum mechanics while preserving Einstein's classical concept of spacetime has been announced in two papers published simultaneously by UCL ...

Quantum information theory is a field of study that examines how quantum technologies store and process information. Over the ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

In this video, we explore the relationship between string theory and quantum field theory (QFT). QFT is a mathematical ...

With the help of a new experiment, researchers have succeeded in confirming a ten-year-old theoretical study, which connects one of the most fundamental aspects of quantum mechanics -- the ...

A new theory of quantum gravity, which attempts to unite quantum physics with Einstein's relativity, could help solve the puzzle of the universe's expansion, a theoretical paper suggests. When you ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...

“EINSTEIN attacks quantum theory.” That was the headline in The New York Times on 4 May 1935. The world’s most famous scientist and two collaborators had discovered what they saw as a fatal flaw at ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...
