Einstein's gravitational waves detected in scientific milestone

Quote

WASHINGTON/CAMBRIDGE, Mass. (Reuters) - Scientists said on Thursday they have for the first time detected gravitational waves, ripples in space and time hypothesized by physicist Albert Einstein a century ago, in a landmark discovery that opens 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, announced at a news conference in Washington, 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.

Like light, gravity travels in waves, but instead of radiation, it is space itself that is rippling. Detecting the gravitational waves required measuring 2.5-mile (4 km) laser beams to a precision 10,000 times smaller than a proton.



So gravity isn't "radiation", i.e., electromagnetic
and as such, doesn't have to obey the FTL speed limit
