'Win for Einstein': Nobel Prize winners find gravitational waves in space

Louisiana's governor and Louisiana State University were quick to note that LSU scientists and the gravity-wave observatory on LSU property participated in discoveries that won the Nobel Physics Prize.

Professor of theoretical physics at Caltech Kip Thorne (R) and Emeritus professor of physics at MIT Rainer Weiss (L) listen to remarks on the discovery of gravitational waves during a press conference in Washington, D.C., last year.

On September 14, 2015, gravitational waves were first observed. He said the Indians contributed especially in "extracting signal from noise, in detecting the gravitational waves".

Gravitational waves are extremely faint ripples in space, generated by some of the most violent events in the universe.

Bangladesh, Myanmar agree to discuss return of Rohingya
More than half a million Rohingya Muslims fled their nation's army as it advanced, crossing into neighboring Bangladesh. This would be done according to criteria agreed in 1993, when tens of thousands of Rohingya were repatriated, she said.

The LIGO project is a collaborative project with over one thousand researchers from more than 20 countries including India.

While the three new Nobel laureates were the pioneers of this work, making invaluable contributions to the LIGO project, this discovery was the product of decades of work by teams of researchers, and Thorne doesn't want to take all the credit.

2, They are formed around 10 million years after two galaxies collide and their central black holes merge - about 100 times faster than previously thought.

Palestinian prime minister rolls into Gaza amid reconciliation hopes

To detect ripples that tiny, scientists use laser interferometers.

Rainer Weiss, 85 was born in Germany and works as a Professor at Massachusetts Institute of Technology.

In describing the process to non-experts, the Swiss Royal Academy of Sciences said gravitational waves "are always created when a mass accelerates, like when a ice-skater pirouettes or a pair of black holes rotate around each other". The waves were detected by two observatories located in Livingston, La. and Hanford, Wash. These can indicate that the space between the mirrors has been warped, thanks to the influence of gravitational waves rolling past.

For the past 25 years, the physics prize has been shared among multiple winners. Those spotted have come from very distant black holes - extraordinarily dense objects whose existence was also predicted by Einstein - that smashed together to form a single, larger black hole.
