My video on where the atmosphere stops: • Where does the atmosphere stop?
According to a scholar living 1,000 years ago in Andalusia, by taking two simple measurements of Twilight and applying some trigonometry you can estimate the height of the atmosphere. In this video I test out the theory, and come up with a height for where space begins.

Where does space begin? How did ancient people know about space? What is Twilight? How can you use twilight to estimate the height of the atmosphere? Is all atmospheric science western? In this science experiment video I answer these questions and more.
