Gravitational waves and the slow pace of scientific revolutions

Enlarge / For years, people weren’t sure if gravitational wave were a necessary product of relativity. (credit: Fermilab) LIGO’s detection of gravitational waves came almost exactly a century after Einstein had formulated his general theory of relativity and an ensuing paper mathematically describing the possibility of gravitational waves. Or at least that’s the story as […]

Neutron Stars Collide, and the Gravitational Wave Sends Ripples Through Astrophysics

Scientists detected their fifth gravitational wave in August, and announced it today. But keeping the discoveries quiet is getting harder and harder. https://media.wired.com/photos/59e1221af7aca336d0f37965/master/pass/GravitationalWaves-694234668.jpg Feed: All Latest

Astronomers just measured a whole lot more than gravitational waves

A couple of weeks ago, the LIGO (Laser Interferometer Gravitational-Wave Observatory) and Virgo teams announced the detection of another set of gravitational waves — the fourth since LIGO’s first detection in September of 2015. The observations of these ripples in spacetime are extraordinary in and of themselves, no matter how many times we record them. […]

Major gravitational waves announcement expected – but what will it be? (POLL)

Published time: 14 Oct, 2017 17:00 Scientists are set to reveal details of their latest gravitational waves discovery on Monday in an announcement that is shrouded in mystery. The Laser Interferometer Gravitational-wave Observatory (LIGO) said it would unveil new developments in the ongoing search for gravitational waves alongside partner scientists from some 70 observatories, but […]

LIGO’s gravitational wave detection takes home a Nobel

A 4km arm of the LIGO interferometer stretches into the foggy distance. (credit: Eric Berger) From almost the moment their discovery was announced, everyone agreed that the first sighting of gravitational waves was going to win a Nobel Prize. The only questions were when and who would receive the honor. Both of those questions have […]

The ESA’s hunt for gravitational waves is over, for now

On July 18th, 2017 at around 2PM Eastern time, Professor Stefano Vitale sent the LISA Pathfinder its final kill commands from the mission’s control center in Germany. The lead investigator’s instructions prompted the probe to reboot itself and run a corrupted version of its software. That ensures that the spacecraft will harmlessly orbit the sun […]
