Though it was a good refresher and in a few areas useful. Eg I knew about dark matter but not dark energy.
There were some fun tidbits too - I found it fascinating that the Moon is 1/400th the diameter of the Sun, but it's also 1/400th as far away from us, so they look the same size in the sky - a pure coincidence. Can you image how weird it would be otherwise?
Another one was how there is a high probability of a killer asteroid hitting earth within the next 100 million years. But that probability would be much larger if we didn't have big brother Jupiter in our system - who is so large that it acts as a shield and bats many asteroids out of harms way.
