Lecture no. 21 from the course: Black Holes, Tides, and Curved Spacetime: Understanding Gravity

Which Universe Is Ours?

Taught by Professor Benjamin Schumacher | 30 min | Categories: The Great Courses Plus Online Science Course

Investigate what Einstein called his “greatest mistake”—his rejection of his own theory’s prediction that spacetime should be dynamic and evolving. Chart the work of a group of scientists, including Alexander Friedman, Georges Lemaître, and Edwin Hubble, who advanced the realization that our universe is expanding from an apparent big bang.
