The sun, moon, and SPACETIME CONTINUUM? On this episode, Neil deGrasse Tyson and comic co-host Chuck Nice break down space and time and other cosmic things you thought you knew. Find out about Einstein's special theory of relativity and our four dimensions. Neil and Chuck make lunch plans as they navigate space and time. What critiques does Neil have of The Terminator and Back to the Future? What are some unintended complications of time travel? Discover the concept of worldlines, getting unstuck from time in Slaughterhouse 5, and how time travel is just a changing of dimensions. Next, Chuck carefully avoids making any moon jokes as we break down myths about the moon. Why does the moon look bigger on the horizon? Is it actually a trick of the eye? You’ll learn an easy trick to undo this illusion. What’s a honey moon? We break down different moons including the creepiest, and also Chuck’s favorite: the blood moon. How big is the sun? We wrap our heads around the scale of our universe and the role of the sun on our planet. If the sun were magically plucked from its spot, how long would it take for us to realize it? How do sunspots work? What about solar flares? We break down the mechanics of the sun’s interior, the merry-go-round effect, and the flipping of the sun's poles. All that, plus, what are fishes’ experiences with the sun?
