What is the difference between fission and fusion? Neil deGrasse Tyson and comedian co-host Chuck Nice take on Oppenheimer, how fission works, and what a full fusion reaction would look like.

We break down how to get energy out of atoms and how radiation works. What is a positron? Learn about the isotopes of Uranium and how it creates a chain reaction. What is more powerful, fission or fusion? Could a nuclear episode ignite the atmosphere?
