Gravitational waves from black holes detected


Scientists are claiming a stunning discovery in their quest to fully understand gravity.

They have observed the warping of space-time generated by the collision of two black holes more than a billion light-years from Earth.

The international team says the first detection of these gravitational waves will usher in a new era for astronomy.

It is the culmination of decades of searching and could ultimately offer a window on the Big Bang.

The research, by the Ligo Collaboration, has been accepted for publication in the journal Physical Review Letters.

The collaboration operates a number of labs around the world that fire lasers through long tunnels, trying to sense ripples in the fabric of space-time.

Expected signals are extremely subtle, and disturb the machines, known as interferometers, by just fractions of the width of an atom.

But the black hole merger was picked up by two widely separated LIGO facilities in the US.

The FTC Antitrust Division shouldn't have allowed that merger.

Hello Albert!
Einstein himself actually thought a detection might be beyond the reach of technology.
Some of us feel similarly about say String Theory. What is impossible eh?

Well he knew that energy equals mass times the speed of light squared.

He made predictions which turned out to be close to reality.

I'm disappointed that insufficient gravitas has been displayed in this thread... :nono:

I remember Wavy Gravy, but I think that's in a different context.
Yeah well that's just, like, your opinion, man.

I once read a weighty tome about anti gravity. It was impossible to put down.

All I want to know is are we going to be able to manipulate gravity now for space travel?

No. And if Seth was here he'd be telling you you were buying into the religion of science.

I don't understand the levity. This is after all a matter of the utmost gravity.
