Nobel Prize goes to physicists who observed gravitational waves

LSU Adjunct Professor and MIT Professor Emeritus Rainer Weiss and California Institute of Technology professor emeriti Kip Thorne and Barry Barish have been awarded this year's Nobel Prize in Physics. Hence why the initial gravitational waves spotted by LIGO came from two massive black holes - both 30 times bigger than our sun - crashing into each other near the speed of light.

The awarding of the prize came after an global team of scientists announced past year the detection of ripples in space-time from two colliding black holes. Detectors have sensed three other gravitational waves since then, all from merging black holes. The project took more than 40 years. The ability to measure gravitational waves is leading to a revolution in astrophysics, according to the Nobel Committee.

There were 37 authors from nine Indian Institutions in the scientific publication presenting the first discovery of gravitational waves published in the Physical Review letters by the LIGO Scientific Collaboration and Virgo Collaboration.

Announcing the winners in Stockholm on Tuesday, the Nobel committee described Ligo as the "most sensitive instrument ever devised by man". Professor Drever, who passed away earlier this year, co-founded the Laser Interferometer Gravitational-wave Observatory (LIGO) with Prof Kip Thorne at Caltech and Prof Rainer Weiss at MIT between 1984 and 1994.

Three American physicists have won the Nobel prize in physics for the discovery of spacetime gravitational waves.

Three U.S. -based scientists won the Nobel Prize in physics on Tuesday for detecting faint ripples flying through the universe - the gravitational waves predicted a century ago by Albert Einstein.

This is something completely new and different, opening up unseen worlds, the statement said.

BREAKING NEWS The 2017 #NobelPrize in Physics is awarded to Rainer Weiss, Barry C. Barish and Kip S. Thorne @LIGO. "This will teach us about the most violent processes in the universe and it will lead to new insights into the nature of extreme gravity".

Prof Thorne made crucial predictions about how to recognise a gravitational wave signal.

University of Washington astrophysicist Krishna Venkateswara, a member of the collaboration, told GeekWire in an email that he was "very proud that the award went to the founders of LIGO, who have inspired the rest of us to pursue this wonderful science".

The Nobel prize winners weren't the first people who thought of using interferometry (a group of techniques in which electromagnetic waves are superimposed, causing the phenomenon of interference, in order to extract information) to detect gravitational waves.

Why do gravitational waves matter to us? Weiss and Thorne, along with Barish, helped make the project a reality.

"I am very excited that it worked out in the end".

The historic announcement in February 2016 that tremors in the very fabric of reality had been traced to the titanic collision of two black holes was widely tipped to be a Nobel Prize victor.
