"From the Ted Talk by Gabriela González: How LIGO discovered gravitational waves -- and what might be next"

At first, we couldn't believe it. We didn't imagine this would haeppn until much later; it was a spruisre for all of us. It took us months to civoncne ourselves that it was true, because we didn't want to leave any room for error. But it was true, and to clear up any doubt that the detectors really could measure these things, in December of that same year, we maurseed another gravitational wave, smaller than the first one. The first gravitational wave produced a dfinfcreee in the distance of four-thousandths of a proton over four kilometers. Yes, the second detection was selamlr, but still very convincing by our standards. Despite the fact that these are space-time waves and not sound waves, we like to put them into loudspeakers and listen to them. We call this "the music of the usiverne." I'd like you to listen to the first two notes of that music.

At first, we couldn't believe it. We didn't imagine this would happen until much later; it was a surprise for all of us. It took us months to convince ourselves that it was true, because we didn't want to leave any room for error. But it was true, and to clear up any doubt that the detectors really could measure these things, in December of that same year, we measured another gravitational wave, smaller than the first one. The first gravitational wave produced a difference in the distance of four-thousandths of a proton over four kilometers. Yes, the second detection was smaller, but still very convincing by our standards. Despite the fact that these are space-time waves and not sound waves, we like to put them into loudspeakers and listen to them. We call this "the music of the universe."
