Wait... if I walk off the edge of the earth, what is pulling me down? What am I falling towards?

How does it work!?!

Rumour has it that the observation is compatible with 29 and 36 solar masses respectively, and that a whopping 3 solar masses worth of energy was radiated away via gravity.

That's a big boom. :p

The set fell out of Losty's ring ??

How did they manage to create black holes in a lab?

The di'nt. They built these things:

which are super-precise laser interferometers which can measure changes in length of their 4km arms far shorter than a proton.
Then they waited until they would see a signal from two black holes merging somewhere in the galaxy. Gravitational waves coming from such events change the metric of spacetime, and therefore cause tiny variations of the relative lengths of the two arms you see in the picture. Those are then picked up where the two laser beams meet.

That's just so remarkable.  Fascinating.

So on to practical applications of all this technology.

How long before we can surf gravitational waves?

I'm thinking surfing a gravitational wave at the speed of light might be a little more thrill than you can stand

They are all around you! What's keeping you, grab a board! You haven't lived until you've felt the power of an entire star being annihilated into energy.
