An upgrade to LIGO that comes from exploiting a quantum rule known as the Heisenberg uncertainty principle makes it easier to detect spacetime ripples.

Earth is awash in gravitational waves. Over a six-month period, scientists captured a bounty of 39 sets of gravitational waves. The waves, which stretch and squeeze the fabric of spacetime, were ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Two black holes whirled violently towards each other, under the pull ...

For 13 years, the scientists of LIGO—the most ambitious, and expensive, project in the history of the National Science Foundation—had been waiting. LIGO, the Laser Interferometer Gravitational-Wave ...

Certain detection of gravitational waves requires at least two detectors located at widely separated sites. Regional phenomena such as micro-earthquakes, acoustic noise, and laser fluctuations can ...

Physicist who won a Nobel Prize for LIGO Hanford observatory in Eastern WA died. LIGO confirmed Einstein’s theory of relativity by detecting gravitational waves in 2015. Twin LIGO sites in WA and LA ...
