What is horsepower? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice break down what horsepower means a unit of measure, and where it comes from. Could we measure explosions in terms of Death Stars? We hop in our horseless carriages and take a ride down what it means for something to have horsepower. What is the power of one horse? We break down engines and the different metrics used to measure their power. What about watts? How much horsepower does a NASA shuttle rocket engine have? What would it take to get millions of horses to run fast enough to get into orbit? We discuss how the power of atomic bombs and hydrogen bombs are quantified. Exploding horses? Death Stars? All that and more, on another StarTalk explainer!
