Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Astronomers have directly observed a spinning black hole twisting spacetime, confirming a century-old prediction of ...

Astronomers have spotted a Saturn-sized world drifting through a region of space that theory once said should be almost empty ...

Researchers at TU Wien have integrated quantum physics with general relativity, revealing significant departures from established models. The study was published in Physical Review D.

Large masses – such as a galaxy – curve space-time. Objects move along a geodesic. If we take into account that space-time itself has quantum properties, deviations arise (dashed line vs. solid line).

In modern physics, the Higgs boson is famous for giving particles their mass. But a new study suggests an entirely different possibility: mass might come from the geometry of hidden extra dimensions, ...

A gravitational singularity refers to a point in spacetime where density and curvature become infinite, and the equations of general relativity no longer provide meaningful predictions. Theoretically, ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...

Binary black hole systems are turning out to produce some of the most important data in modern astronomy. Credit: NASA's Goddard Space Flight Center A new study in the scientific journal Nuclear ...

A new study reveals that even small differences in elevation between quantum computers—just one kilometer apart—can allow Earth’s gravity to measurably affect quantum systems, challenging one of the ...

URBANA, Ill. — Three atomic clocks, each no bigger than a grain of sand, suspended at different heights around a city. But these aren’t ordinary timepieces; they’re quantum devices that exist in ...
