The Times They are a-Changin': Gravity Waves, Moore’s Law, and Record Basketball

Thursday, February 11th, 2016

Big changes happened this week.

First, gravity waves have been detected for the first time in an announcement on Feb. 11.  This confirms a major prediction of Albert Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos. Physicists have concluded that the detected gravitational waves were produced during the final fraction of a second of the merger of two black holes to produce a single, more massive spinning black hole. This collision of two black holes had been predicted but never observed.

The gravitational waves were detected by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. The LIGO Observatories  were conceived, built, and are operated by Caltech and MIT.

Last March, researchers completed major upgrades to the interferometers, known as Advanced LIGO, increasing the instruments’ sensitivity and enabling them to detect a change in the length of each arm, smaller than one-ten-thousandth the diameter of a proton(!). By September, they were ready to start new observations and then saw the black hole merger. (more…)
