In September 2015, scientists witnessed something never seen before: two black holes colliding. Both about 30 times as big as our Sun, they had been orbiting each other for millions of years. A fraction of a second before the crash, they sent a vibration across the universe at the speed of light that was picked up by the LIGO detector. So what are these ripples in space? Amber L. Stuver explains.

A few weeks ago a large team of gravitational wave astronomers announced something pretty wild. The moderately confident detection of pervasive ripples in the fabric of space time that presumably fills the cosmos, detected by watching for subtle connections between the signals from rapidly spinning cores of dead stars in our galactic neighborhood. In other words, the gravitational wave background has probably been detected using a pulsar timing array.

Gravitational Waves: A New Era of Astronomy Begins
On September 14th, 2015, a ripple in the fabric of space, created by the violent collision of two distant black holes over a billion years ago, washed across the Earth. As it did, two laser-based detectors, 50 years in the making – one in Louisiana and the other in Washington State – momentarily twitched, confirming a century-old prediction by Albert Einstein and marking the opening of a new era in astronomy. Join some of the very scientists responsible for this most anticipated discovery of our age and see how gravitational waves will be used to explore the universe like never before.
This program will feature exclusive footage from director Les Guthman’s upcoming documentary chronicling the drama of the gravitational waves discovery.

A lot of videos have covered the general overview of the discovery of gravitational waves, what they are, the history of the search, when they were found but I wanted to delve into the absurd science that made the detection possible.
When scientists want one megawatt of laser power, it's not just for fun (though I'm sure it's that too), it's because the fluctuations in the number of photons is proportional to their square root, making more powerful beams less noisy (as a fraction of their total). The smoothest mirrors were created not for aesthetic joy but because when you're trying to measure wiggles that are a fraction the width of a proton, a rough mirror surface simply won't do.

On September 14th, 2015, a ripple in the fabric of space, created by the violent collision of two distant black holes over a billion years ago, washed across the Earth. As it did, two laser-based detectors, 50 years in the making – one in Louisiana and the other in Washington State – momentarily twitched, confirming a century-old prediction by
Albert Einstein and marking the opening of a new era in astronomy. Join some of the very scientists responsible for this most anticipated discovery of our age and see how gravitational waves will be used to explore the universe like never before.
This program will feature exclusive footage from director Les Guthman’s upcoming documentary chronicling the drama of the gravitational waves discovery.
