Using a chain of atoms in single file to simulate the event horizon of a black hole, a team of physicists in 2022 observed ...

Ten years ago, astronomers made history when they first detected ripples in spacetime, called gravitational waves, from the ...

For decades, physicists have faced one of science’s greatest puzzles: merging quantum mechanics, which describes tiny particles, with general relativity, which explains the universe’s vast structures.

"GW250114 is the loudest gravitational wave event we have detected to date; it was like a whisper becoming a shout." ...

A fresh black hole merger detection has offered the clearest evidence yet for Einstein’s relativity and Hawking’s predictions ...

A radical new theory regarding the origin of the universe suggests that gravitational waves, tiny ripples in spacetime first ...

New observations of two black holes merging have confirmed predictions made decades ago by Albert Einstein, Stephen Hawking, ...

This article explores how our understanding of the universe has evolved—from the scale of everyday experience down to the ...

Stephen Hawking's 50-year-old theorem on how black holes merge together has been successfully tested thanks to huge advances in gravitational wave astronomy, which helped astronomers catch the waves ...

Ripples in spacetime now give astronomy a second sense. The network listens to collisions, maps a low-frequency background ...

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 ...

Cold atom experiments are among the most powerful and precise ways of investigating and measuring the universe and exploring ...
