We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole new model to account for gravity’s influence.

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called ...

Theoretical physicists have spent decades wrestling with a disorienting possibility: that the flow of time is not woven 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 ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama themselves. A new theoretical framework now flips that script, treating space ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

As my arms lift from my sides, and the rest of my body follows suit toward the ceiling of a modified Boeing 727—next to scientists, astronauts, engineers and activists—I think, “How did I get here?” I ...

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 ...

The study of higher dimensional gravity theories represents a vibrant and innovative field in modern theoretical physics. At its core, this research seeks to extend the familiar four-dimensional ...

With more than $20 million in contracted mission funding to date, the Quantum Gravity Gradiometer Pathfinder Mission, Led by NASA’s Jet Propulsion Laboratory in Southern California, Advances U.S.
