Earlier this month, physicists succeeded in directly detecting gravitational waves, 100 years after Albert Einstein predicted them. The discovery made international news. We'll learn about the importance of the discovery and get a primer on Einstein's Theory of Relativity. We'll also discuss the latest news from around our galaxy - including the mysterious Planet 9.
