This video is about how Einstein’s theory of general relativity has evolved over more than 100 years. Many models and theories of gravity have been developed, which can be organized into four main schemes.

0:00 Introduction
1:00 The Incompleteness of the Standard Model of Cosmology
2:54 How to Modify General Relativity
5:12 Four Paths Beyond General Relativity
6:09 First Scheme: Adding New Fields to GR
10:18 Second Scheme: Adding Higher-Order Curvature Invariants to GR
14:03 Third Scheme: Modifying the Geometry of GR
17:54 Fourth Scheme: Quantizing General Relativity
22:37 Conclusion
