# Astronomy Lesson 24: General Relativity Curvature and Tests

General Relativity is one of the most successful theories of Physics. It helps us give a mechanism to gravity, and allows for testable predictions. We'll chat about the Correspondence Principle, The Equivalence Principle, intertial versus gravitational mass, and the nature of spacetime curvature and how it's measured. We'll chat about various tests of general relativity, and how they showed that it's the best explanation so far to the nature of space, time and gravity.
