This was a great lecture. The speaker is a astrophysical scientist so she had a great amount of knowledge about space. She talked about things like how they try to figure out how big the universe is. And tests they use to try to figure out when the universe first started. She talks about the sun, and black holes. It was fascinating to hear it coming from somebody with her backgroud. HIGHLY RECOMMEND!
