Loading ...In a landmark discorvery, ripples in space and time first hypothesized by physicist Albert Einstein a century ago have been detected, with scientists suggesting that the observation of these gravitational waves could now open a new window for studying the cosmos.
The researchers said they detected gravitational waves coming from two black holes —extraordinarily dense objects whose existence also was 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.
The scientific milestone was achieved using a pair of giant laser detectors in the United States, located in Louisiana and Washington state, capping a long quest to confirm the existence of these waves.
The announcement was made in Washington by scientists from the California Institute of Technology, the Massachusetts Institute of Technology and the LIGO Scientific Collaboration.
Gravity travels in waves, like light and other forms of radiation. But with gravitational waves it is space itself that is rippling.
