Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...

Researchers at Hiroshima University have developed a realistic, highly sensitive method to detect the Unruh effect—a long-predicted phenomenon at the crossroads of relativity and quantum theory. Their ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein's general relativity. One explains the tiny world of particles; the other describes ...

Gravity, the force that attracts objects toward each other, is currently framed by Albert Einstein's theory of general ...

The proposed BMV experiment could test whether gravity is quantum, a breakthrough that may lead to quantum computers and ...

The Earth’s gravity, manifested as curvature in space and time, is expected to alter the rules of standard quantum theory. An experiment consisting of three quantum computers at different elevations ...

Quantum foam's implications for spacetime fluctuations are crucial for addressing key questions in physics, from black holes ...

NASA's upgraded Cold Atom Lab came back online aboard the International Space Station this week — the fourth and final hardware overhaul of a facility that has spent eight years turning the ISS into ...

The first step toward quantum gravity, the "holy grail of physics," may be hiding in a quantum recipe to cook up black holes. That's the suggestion of new research that adds quantum corrections to ...
