1,000,000,000,000,000,000,000. That’s the estimated number of stars in the universe. That’s a pretty big number. But, how did we get here? And, can we go bigger? You bet we can go bigger. In this video, Neil deGrasse Tyson and comic co-host Chuck Nice are here to help you understand how big some numbers truly are.

We have to start small. Neil takes us from a simple million to a billion and then way beyond anything you’re imagining. You’ll learn how many stars are in our galaxy. And, how many galaxies are in our universe. What does the number really mean in the scale of everything?

How long would it take you to count to a billion? How long would it take you to count to a trillion? Then, we cross the point where numbers get so big that you have to start using words to describe them. Discover more about a mole, a googol, a googolplex, and Skewes’ number. After this video, you’ll look at numbers a whole different way!
