Neil deGrasse Tyson Explains The Equivalence Principle

Does being in space mean there is no gravity? Neil deGrasse Tyson and comedian Chuck Nice explore gravity, acceleration, and Einstein’s equivalence principle. Are astronauts always floating when they’re in space?

What does it mean to escape Earth's gravitational pull? Find out what 0 G really is as we explore the concept of weightlessness. What is a translunar injection? We discuss Lagrange points, The Expanse, Ad Astra, and transitioning between objects’ gravitational pulls. Can a person on a rocket tell between 1G of gravity and 1G of acceleration? Plus, is microgravity actually a misnomer?
