It's truly incredible that I can sit here, plug my headphones into this little electrical box and "hear" the gravitational sound of two black holes colliding. If only Mr. Einstein could be here to listen.

I love that the data-as-sound is so cute: https://losc.ligo.org/s/events/GW151226/GW151226_template_sh...

Truly an unbelievably jaunty little sound considering that it represents the entire mass of our solar system being converted into energy. Yow.

Indeed. And to put that into perspective:

"The amount of matter converted to energy in the atomic bomb dropped on Hiroshima was about 700 milligrams, less than one-third the mass of a U.S. dime."
