Now we are learning about aliens. Awesome.
Today we are learning about Fermi's Paradox. Enrico Fermi was a famous physicist who figured out that there has been enough time for intelligent alien life to colonize the galaxy, yet we cannot detect their presence today. This is a paradox, which is a self-contradictory idea.
Here is a great visual explanation of Fermi's Paradox:

Later on, another physicist checked Fermi's math and developed this formula:
This is the Drake equation. When it was initially solved, using what we knew about the milky way galaxy in the 60's, the solution estimated that there should be 10,000 intelligent civilizations in the milky way galaxy. Today, we know more about the milky way and the current solution is that there should be 0.08 intelligent civilizations in our galaxy. This is weird because we know of at least 1.
