Long ago, in a galaxy far away, two black holes danced around each other, drawing ever closer until they ended in a cosmic collision that sent ripples through the fabric of spacetime. On September 14, ...

Could it be that the universe’s first structures were born not from enigmatic inflaton fields, but from the echoes of ancient ...

Less than a decade since the first detection of gravitational waves—ripples in spacetime itself—proposed budget cuts threaten ...

Scientists propose using quantum-entangled clocks to test how gravity affects quantum mechanics in curved spacetime.

The findings suggest that sufficiently small particles introduced into the laboratory vortex should behave similarly to dust ...

A new study published in the journal PRX Quantum demonstrates how a network of quantum computers employing optical clocks can ...

At the center of each classical black hole is a paradox: a singularity, where gravity is infinite and the laws of physics break down. But a new theoretical breakthrough says such cosmic dead ends aren ...
