The institute saw the three make decisive contributions towards the LIGO detector, which helped prove the concept brought out by Albert Einstein's Theory of Relativity.

Sweden's Royal Academy of Sciences announced on Tuesday that the winners are Rainer Weiss of the Massachusetts Institute of Technology and Barry Barish and Kip Thorne of the California Institute of Technology.

The breakthrough came with the construction of the Laser Interferometer Gravitational-Wave Observatory (LIGO), a collaborative project with more than 1,000 researchers from more than 20 countries.

Killed in Marseille in 'Likely Terrorist Act'
Last month, four female American college students were sprayed with hydrochloric acid at the Saint Charles station. The 41-year-old woman who attacked them was later arrested and police said she had a "psychiatric history".

The Laser Interferometer Gravitational Wave Observatory (LIGO) was designed and built specifically to observe that phenomenon, and in September 2015 the very first detection was confirmed. "It's really wonderful, but I view this more as recognition of around 1000 people who contributed and a result of dedicated efforts over 40 years", said Weiss, reacting to the announcement.

Glasgow University physicists have been working to prove the existence of gravitational waves for almost 50 years and helped develop sensors used by Ligo. These gravitational waves will assure important process for the humanity to traverse the Universe. Raymond Davis Jr., who was 88 years old when he was awarded the Nobel Prize in 2002, is the oldest.

The tumour was a "long lost Playmobil traffic cone" that the man had received as a birthday present when he was seven years old. Mohammed Munavvar at the Royal Preston Hospital in the United Kingdom , according to a BMJ Case Report published Saturday.

Weiss, a professor emeritus at MIT, was born in Germany in 1932 and immigrated to the United States in January of 1939, escaping the Nazi regime, Haaretz reported. These "waves" would propagate outward at the speed of light, but the waves themselves were extremely faint. The beams are used to detect infinitesimal changes in the distance between mirrors at the ends of the arms that are caused when gravitational waves pass by the detectors.

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