Neil deGrasse Tyson Explains Why Some Info Is Need to Know
When someone says that information is on a “need to know” basis, your mind might automatically think that the information is secretive, dangerous, etc. But, there’s another type of “need to know” information that involves different “levels” of information.
On this StarTalk explainer video, Neil deGrasse Tyson and comic co-host Chuck Nice are exploring these different “levels” of information. We discuss why, in certain circumstances, an idea is better than the details. To understand these levels of information, we explore the Earth’s orbit around the Sun. You’ll learn why you can say the Earth goes in a circle around the Sun and be “correct” even though it’s actually an elliptical orbit. And you can say it’s an elliptical orbit even though it’s actually a loop-de-loop!
Find out how Earth’s tilt influences our seasons. You’ll also find out about the “libration” of the Moon or as Chuck calls it “Moon twerking.” And, we discuss Earth’s precession around the Sun. Lastly, Neil uses the size of the Sun as another example of understanding different levels of information. All that, plus, we explore why the scientific method allows for the possibilities of change.
