Brian Greene sits down with Leonard Susskind for a conversation about the mysteries of the universe.

Quantum physics is a branch of physics that deals with the behavior of matter and energy at the smallest scales, such as atoms and subatomic particles. It is based on the principles of quantum mechanics, a theory developed in the early 20th century to explain the strange and unpredictable behavior of matter and light. In quantum mechanics, particles can exist in multiple states at the same time, and their behavior is determined by probability. This is in contrast to classical physics, where part

Light, stopped. Inside the atoms.
