USA physicists win Nobel Prize for discovery of gravitational waves

LIVE Sweden's Nobel Prize in Physics 2017

Weiss, Barish and Thorne will share in the Nobel prize of 9 million Swedish Krona (£834,264/$1.1 million).

Gravitational waves were predicted by Albert Einstein a century ago as part of his theory of general relativity. He says the Prize is well deserved because the work has opened up a new window in astronomy that allows physicists new insights into black holes and neutron stars.

Three American physicists working on gravitational waves on the Laser Interferometer Gravitational-Wave Observatory (LIGO) project has been awarded Nobel Prize in Physics.

Gravitational waves from the black hole collision 1.3 billion years ago were detected on September 14, 2015, by twin Laser Interferometer Gravitational-Wave Observatory (LIGO) detectors in Louisiana and Washington sate, the LIGO Scientific Collaboration team said in February 2016.

And now, as well as using visible light, infrared and radio waves to observe the universe, astrologists could start trying to detect gravitational waves, too. Technically, anything with mass creates these waves, but it takes cataclysms on a big scale, such as the merging of two black holes, to generate gravitational waves strong enough for us to detect - and even then, by the time they reach Earth, the disturbances are occurring on a subatomic scale.

Ryan Gosling Couldn't Stop Cracking Up on SNL Last Night
However, this was not the only noteworthy sketch in the SNL season premiere . No matter your personal crusade, there's an angry Ryan Gosling for you .

LSU said in a news release that its scientists have spent more than four decades on gravitational-wave research, one of the longest-running such programs among institutions contributing to the discovery.

LIGO is a vast complex based out in the U.S. that uses two vast laser interferometers to detect what are quite simply ripples in space and time. The laser device, called an interferometer, must be both precise and extremely stable.

Weiss is a professor emeritus of physics at MIT.

The waves came from a collision between two black holes.

Married to a film producer, he heavily consulted on the film Interstellar, and his own calculations helped the special effects team create realistic visuals of black holes.

A professor at the Massachusetts Institute of Technology has won the 2017 Nobel Prize in Physics. The group of the people initiated the foundation work on developing data analysis techniques which are done to detect the weak gravitational wave signals buried in the detector's noise.
