The Past Hypothesis

Lecture no. 11 from the course: Mysteries of Modern Physics: Time

The Past Hypothesis

Taught by Professor Sean Carroll | 28 min | Categories: The Great Courses Plus Online Science Course

Boltzmann explains why entropy will be larger in the future, but he doesn’t show why it was smaller in the past. Learn that physics can’t account for this difference except by assuming that the universe started in a state of very low entropy. This assumption is called the past hypothesis.
