What is antimatter? Neil deGrasse Tyson and Chuck Nice break down what antimatter is and how our matter-based universe came to be. What happens when matter and antimatter annihilate? We break down positrons and the anti-quarks that makeup anti-neutrons. Is there an opposite universe where everything is antimatter? Plus, learn about energy mass conversion and its role in how our universe came to be.
