Caltech Scientists Share 2017 Nobel Prize for Discovery of Gravity Waves

The Nobel prize for physics has been awarded to three scientists who were the first to observe gravitational waves. Kip Thorne and Rainer Weiss had already believed in the presence of gravitational waves. First anticipated by Albert Einstein nearly a century ago, three American scientists have finally vindicated him nearly one hundred years on.

Ariel Goobar of the Royal Academy said the winners' work meant "we can study processes which were completely impossible, out of reach to us in the past".

Mr Weiss, who was born in Germany, was awarded half of the 9-million-kronor (US$1.1m) prize amount, while Mr Thorne and Mr Barish will split the other half.

Three pioneers of the Laser Interferometer Gravitational-wave Observatory, or LIGO, which announced previous year the detection of gravitational waves for the first time, have been awarded the 2017 Nobel Prize in physics.

LSU physics and astronomy professor Gabriela Gonzalez was the elected spokeswoman for the LIGO Science Collaboration, or LSC, when the observatories announced in 2016 that they had first detected a gravity wave in late 2015, the university's release noted.

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.

Steve Daines, a Republican , also called the program critical for Montana but was more optimistic about quick action in Congress. The law does allow unspent funds from previous years to carry forward, so states now are relying on those accounts.

"The information encoded in those gravitational waves tells us about the universe, how stars evolve, how they live, how they die", Brown said. Weiss was awarded half of the prize for developing the strategy used at LIGO to make the gravitational wave detection. These can indicate that the space between the mirrors has been warped, thanks to the influence of gravitational waves rolling past.

The laser device, called an interferometer, must be both exquisitely precise and extremely stable. The first trace at Hanford, Washington state, matched nearly exactly the second at Livingston, Louisiana, 3000 kilometres away.

With Tuesday's announcement, the total number of Physics Nobel Prize recipients has increased to 206 (the total number of Prizes is 207; John Bardeen received the award twice).

There were 39 authors from the same nine Indian institutions in the publication for the detection of the second black hole merger event.
