Gravitational waves

Rainer Weiss, Barry Barish and Kip Thorne share the 2017 prize for their work at LIGO to detect ripples in space-time.

Technology far exceeded expectations in LISA Pathfinder test.

A momentous signal from space has confirmed decades of theorizing on black holes — and launched a new era of gravitational-wave astronomy.

The discovery of ripples in space-time has vindicated Einstein — but it can also do so much more.

Historic discovery of ripples in space-time meant ruling out the possibility of a fake signal.

LIGO 'hears' space-time ripples produced by black-hole collision.

On LIGO’s big day, Nature chronicles the search for Einstein's predicted ripples in space-time.
