Episode 8

This episode was focused on constellations and how the universe changes overtime as well as some of the phenomenon that we can observe. Sagan talked about red shifts and blue shifts and how they can tell us things about distant stars. He also talked about Einsteins theory of relativity and how one day we could have spacecraft that travel close to the speed of light. Overall this was one of my favorite episodes just because of how informative it was and how it covered a wide range of topics.
