This course gave a unique insight into our understanding of the universe. I really enjoyed it because it explored the world from start to end. I also loved the Journey of the Universe full film because of the deep understanding of the Universe that Tucker and Grim and Swimme have. However, I found the first few videos confusing, and did not really understand what was going on. The quizzes at the end of each unit were not available to me because I had not purchased the course. Overall though, I think it was amazing and recommend it to anybody who is interested in science or history.
