Cosmic Antigravity—Inflation and Dark Energy

Lecture no. 22 from the course: Black Holes, Tides, and Curved Spacetime: Understanding Gravity

Cosmic Antigravity—Inflation and Dark Energy

Taught by Professor Benjamin Schumacher | 31 min | Categories: The Great Courses Plus Online Science Course

Using everything you’ve learned about gravity, investigate cosmic antigravity, starting with cosmic inflation, a phenomenon that exponentially increased the size of the universe during the big bang. Then, learn why dark matter cannot be made of ordinary protons and neutrons, and explore the recent discovery that the expansion of the universe is accelerating, powered by a mysterious dark energy inherent in space itself.
