Long read, but fascinating if you're an astronomy buff:A team of physicists who can now count themselves as astronomers announced on Thursday that they had heard and recorded the sound of two black holes colliding a billion light-years away, a fleeting chirp that fulfilled the last prophecy of Einstein’s general theory of relativity. That faint rising tone, physicists say, is the first direct evidence of gravitational waves, the ripples in the fabric of space-time that Einstein predicted a century ago (Listen to it here.). And it is a ringing (pun intended) confirmation of the nature of black holes, the bottomless gravitational pits from which not even light can escape, which were the most foreboding (and unwelcome) part of his theory. More generally, it means that scientists have finally tapped into the deepest register of physical reality, where the weirdest and wildest implications of Einstein’s universe become manifest. These chirps are gravitational waves converted to audible sounds. The faint thump matches the gravitational waves’ frequencies. The louder chirp is a higher frequency better suited to human ears. LIGO If replicated by future experiments, that simple chirp, which rose to the note of middle C before abruptly stopping, seems destined to take its place among the great sound bites of science, ranking with Alexander Graham Bell’s “Mr. Watson — come here” and Sputnik’s first beeps from orbit.

Very cool! If there are waves,then there are potential crests where gravity folds back over itself. If gravitational waves can be stretched,they can also be compressed. If they can be compressed,you can cross the space between the crests much easier, using gravity itself as propulsion. Since gravity waves travel at the speed of light, you then can, theoretically, travel faster than light by jumping from crest to crest. Identifying the source of a gravity wave would mean predictablilty to the jumps as well. Hawkings still hasn't caught up with Einstein yet.  Ed

Had to grin at the mention of the Coon-ass hunters shooting the one in Louisiana. If you don't know what the hell it is, just shoot it to see what happens!

What I don't understand is why they are seeing so few of them. Seems like the waves would be a common occurrence in an infinite universe.

Because they are very small. Takes something very massive to effect space time and it diminishes according to the inverse square law.

OK, I was just going on the graphics on the video attached to the story.
Out of curiosity, if they aren't waves as we know of them, what form do they take?

They are like radio waves, which are traveling strengthenings/weakenings in a electric field.

Hard to detect something when you're in the bottom of a well.

Has anyone checked to make sure that this is solid and not caused by some members of the research team turning an electric can opener on and off?

So we have scientific information showing black holes have so much gravity light can't even escape. With that I ask, How did a singularity inflate and expand when all the black holes in the whole universe were there? To believe that requires blind faith in the unseen and untestable.

I never knew about Ligo in Livingston. Hell, I lived not far from there but before they built it. I love this crap.

Ringman lecturing on blind faith has a certain irony, doesn't it.
