Gravity Waves
Posted: Sat Feb 06, 2016 10:17 am
Physicists have theorized about gravitational waves for a century, and they made indirect observations long ago that provided some confirmation. But because measuring gravitational waves requires extraordinary precision, researchers have yet to directly detect them. Now after nearly four decades of planning, building, and upgrading LIGO facilities in the states of Louisiana and Washington, physicists appear to be close.
Perhaps very close.
About two weeks before I visited the Louisiana laboratory, a well-known theoretical physicist named Lawrence Krauss fired off a tweet that reverberated around the physics community: “My earlier rumor about LIGO has been confirmed by independent sources. Stay tuned! Gravitational waves may have been discovered!! Exciting.” This was subsequently retweeted more than 3,400 times.
