In a landmark discovery for studying the cosmos, researchers have for the first time detected gravitational waves, ripples in space and time which were hypothesized a century ago by physicist Albert Einstein.
The announcement was made by scientists from the California Institute of Technology, the Massachusetts Institute of Technology and the LIGO Scientific Collaboration at a news conference on Thursday in Washington.
They said they detected gravitational waves coming from two black holes – extraordinarily dense objects whose existence was also foreseen by Einstein – that orbited one another, spiraled inward and smashed together.
They said the waves were the product of a collision between two black holes 30 times as massive as the Sun, located 1.3 billion light years from Earth.

How gravitational waves propagate? A century after Albert Einstein proposed their existence, there are ripples of excitement in the scientific community about possible confirmation of existence of gravitational waves, a discovery that could open a new window on the universe.Posted by euronews on Thursday, 11 February 2016
