To find out more, visit: https://brilliant.org/SpaceTimeNow 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.

It's Okay to be Smart and PBS Eons!)https://www.youtube.com/watch?v=GcfLZSL7YGw&t=25sWe 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.Reinterpreting Low Frequency LIGO/Virgo Events as Magnified Stellar-Mass Black Holes at Cosmological DistancesBroadhurst, Diego and Smoot (2018)https://arxiv.org/abs/1802.05273On Stellar-Mass Black Hole Mergers in AGN Disks Detectable with LIGOMcKernan et al. 2018https://arxiv.org/abs/1702.07818Stars as Resonant Absorbers of Gravitational WavesMcKernan, Ford, Kocsis and Haimanhttps://arxiv.org/abs/1405.1414Hosted by Matt O'DowdWritten by Drew Rosen and Matt O'DowdProduced by Rusty WardGraphics by Grayson BlackmonAssistant Editing and Sound Design by Mike Petrow and Linda HuangMade by Kornhaber Brown (www.kornhaberbrown.com)Special thanks to our Patreon Big Bang, Quasar and Hypernova Supporters: Big BangCoolAsCatsDavid NicklasFaisal SaudAnton LifshitsJoey RednerFabrice EapQuasarTambe BarsbayMayank M.
