Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

At the quantum scale, systems do not exist in isolation. They interact, exchange information, and become correlated with one ...

The entangled clocks can test how quantum theory behaves in the presence of curved space-time as predicted by Einstein, or whether our current theories break down. Hoboken, N.J., July 14, 2025 — ...

Theoretical breakthrough shows that time’s arrow can emerge naturally from how quantum parts become interconnected.

A new experiment using Google’s Sycamore quantum processor has taken a bold step toward testing ideas from quantum gravity. For the first time, researchers successfully sent quantum information ...

Their work introduces a new concept called q-desics, short for quantum-corrected paths through space–time. These paths generalize the familiar trajectories predicted by Einstein’s general theory of ...

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.

Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...

The ball rolls across the floor because it was kicked, just as Earth orbits the sun because it is tugged by gravity. The connection between cause and effect is fundamental to how we understand the ...

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

Every year, Santa Claus races around the globe in a matter of hours to bring presents to children all over the world.
