Neil deGrasse Tyson Explains Worldlines

What do Zoom calls and Einstein’s Theory of Relativity have in common? On this explainer, Neil deGrasse Tyson and comic co-host Chuck Nice explore worldlines and the technology that is helping us hack the spacetime continuum and track particle paths through spacetime. What is a worldline? Learn about the connection between space and time. What are the ways you could prevent an asteroid from hitting Earth? You’ll also learn about telephones, worldlines, and how a time machine would work. How does Zoom break down the space-time continuum?
