Muchas gracias to Alejandro Cárdenas-Avendaño for inviting me to give a webinar for the Lating American Webinar on Physics (lawphysics). Want to hear me talk about numerical relativity and theories beyond GR? Well, you’re in luck, because the transmission is on YouTube for you to watch! It was really fun, and viewers had great questions.

Title: Testing Einstein with numerical relativity: the precision frontier, and theories beyond general relativity
Abstract: Advanced LIGO and Virgo have already detected black holes crashing into each other ten times. With their upgrades we anticipate a rate of about 1 gravitational-wave detection per week. More signals and higher precision will take the dream of testing Einstein’s theory of gravity, general relativity, and make it a reality. But would we know a correction to Einstein’s theory if we saw it? How do we make predictions from theories beyond GR? And do current numerical relativity simulations have enough precision that we could be confident in any potential discrepancy between observations and predictions?
