SciShow: The Ghostly Particles That May Have Unbalanced the Universe

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: Almost all matter in the universe should have been annihilated shortly after the Big Bang, but looking around, we see galaxies, stars, planets, and, you know... us. So obviously that didn't happen, and the why of it may have something to do with neutrinos. Hosted by: Hank Green SciShow has a spinoff podcast! It's called SciShow Tangents.
