Move number four is my adventure in watching four episodes of Neil DeGrasse Tyson's Cosmos: A Space-Time Odyssey. I really liked this show because it is hosted by Neil DeGrasse Tyson who is the person that I first started reading and watching lectures on when I became interested on the topic. After looking at what black holes and other topics like relativity present I wanted to take a step to learn more about what people are learning right now and have already learned. Cosmos allowed me to learn about these already discovered topics, but also see who discovered what was once thought to be the impossible in their day and age. These episodes covered everything from comets to supernovas. However, there are three topics that I really found most intriguing in these episodes: comets, supernovas, and dark matter.
