Dark matter
One of the things you work on and write about is dark matter. We can't see it, but there's a lot of it in the universe. You also end one of your books with a Beatles song quote, "'Got to be good-looking because he's so hard to see." What is dark matter? How should we think about it given that we can't see it? How should we visualize it in our mind's eye? I think one of the really important things that physics teaches you is just our limitations, but also our abilities. The fact that we can deduce the existence of something that we don't directly see is really a tribute to people that we can do that. It's also something that tells you, you can't overly rely on your direct senses. If you just relied on just what you see directly, you would miss so much of what's happening in the world.
