Teach Astronomy - Baryon Density
http://www.teachastronomy.com/ There are two fundamentally different types of matter in the universe. Baryons is the term that refers to normal matter: the stuff that we're made of; our world, the Earth, the Sun, most of the universe we're familiar with. It's the normal material of matte

In this video I explain just what physicists mean when they speak about "dark matter" and what reasons we have to think that dark matter exists. In my two follow-up videos, I speak about the alternative explanation, modified gravity, and explain why the right solution might well be a combi
