man there's some freaky shit in space, if I werent so dumb id like to be an astrophysicist to understand these kind of things better
waiting for some sci-show coverage on it so i can understand it a bit better 8)
can't wait for the new era of hollywood sci-fi movies to explore this theme while wildly distorting its meaning
This should be the animation of the collision between the 2 blackholes giving birth to the gravitational waves

maelstromthe cool thing is that einstein predicted gravitational waves were possible back in 1915 in general relativity
after 100 years of searching we've finally found them, very exciting
Yeah exactly! After all this is "just" a corroboration of a theory that one single genious thought with his own mind. That's just astonishing!

Way more hyped for this than for the solar system possibly having a ninth planet again.
Based on the observed signals, LIGO scientists estimate that the black holes for this event were about 29 and 36 times the mass of the sun, and the event took place 1.3 billion years ago. About 3 times the mass of the sun was converted into gravitational waves in a fraction of a second—with a peak power output about 50 times that of the whole visible universe.
This is actually insane. And that doesn't even include energy released through other means during the collision, though I'm not really sure a black hole collision would produce light...
I wonder if these kind of events are much more common than we previously thought, and we have just don't see them often (because black holes) or if the discovering scientists got lucky finding these waves so quickly. This detection came before the official observing run even started, so presumably they have many more data that have yet to be analyzed and reduced. Having recurrence rates and distributions for these kinds of events would be amazing.
I really hope these observatories become a standard for observing/early detection of large gravitational events in the next couple years, instead of just a means to further prove one of the most widely accepted and understood theories in physics.
I see it going the same route as neutrino detectors where a couple were built at first just to see if they were there, and now there are a number of them all working together for much more than mere detection.

I'm pretty sure it would produce some kind of electromagnetic radiation, even tho it's not observable.

The massive data dump on the official website has a bunch of neat links.
#6 This is the simulated collision of the measured event.
orbitif the discovering scientists got lucky finding these waves so quickly.
The detectors just finished their massive upgrade when they measured the signal. Interestingly, the detectors have computer systems that make fake "results" to both keep the scientists on their toes when they are analyzing the signal and to make sure that the detector is working. However, because they had just finished the upgrades that system wasn't even on, so the detected signal must have been a gravitational wave.
