15:16Now PlayingIf you’re trying to get in shape you need to lose weight, right? Neil deGrasse Tyson says wrong. On this StarTalk explainer, Neil and comic co-host Chuck Nice are breaking down the differences between mass, weight, and density.
To start, Neil tells us why when you want to get in shape, you need to lose mass. You’ll learn why a weight-loss book written by a physicist would just be one sentence. We explore the difference between mass and weight and why weight is all about forces.
Then, we move on to density. Find out why heavy cream is lighter than skim milk. We explore how the hull of a ship keeps the ship buoyant. All that, plus, Neil explains why, if you want to lose weight quickly, just head to the Moon and hop on a scale.
