I think the most interesting thing I learned was about dark matter and dark energy, and understand the way scientists look at it, and how that plays into "space archeology". This has allowed us to attempt forecasts, and then by studying what happened far away, test our hypothesis to see if we really can predict the future. I've always thought of dark matter and dark energy as these sci-fi concepts, but it was interesting to hear about how they are real things that astronomers study and use to enhance our understanding of the universe.
I would have asked Professor Loeb "How does your work outside the planet affect the way other scientists conduct research on earth?"
