Now that gravitational waves are definitely a thing, it’s time to think about some of the crazy things we can figure out with them. In some cases we’re going to need a gravitational wave observatory - in fact, we've already built one.

We are at the cusp of a golden age of gravitational wave astronomy. We’ve already talked about the Laser Interferometer Gravitational Wave Observatory–LIGO, and the first discovery of gravitational waves here. Those videos came out almost two years ago. A lot has happened since then. First, an update on LIGO. In its two and a half years of operation, LIGO has observed five certain black hole–black hole mergers. These events have been consistently surprising.
