The question of how gravity interacts with the quantum world has long perplexed physicists, but a non-quantum theory of space ...

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.

Everything around us, from atoms and molecules to planets and galaxies, is governed by two extraordinarily successful ...

For over a century, scientists have thought of time as a fundamental property of the universe. But the more researchers seek ...

Forbes contributors publish independent expert analyses and insights. An award-winning reporter writing about stargazing and the night sky. Two cutting-edge atomic clocks — the most accurate ever ...

Gravity used to be the most dependable rule in the cosmic rulebook, the quiet background force that never changed its mind. Now a series of discoveries and bold claims are turning that certainty into ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

Newton’s law of universal gravitation conceived gravity as a force acting at a distance within an absolute Euclidean space and universal time. This framework was superseded by the geometric paradigm ...

Quantum networking is being rapidly developed world-wide. It is a key quantum technology that will enable a global quantum internet: the ability to deploy secure communication at scale, and to connect ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...
