Dark Matter and Energy
One of the courses I teach, Astronomy, is such a delight. I get to see, again and again, the awe in my students as I show them images and videos of various objects in the universe. Just showing a close up of the Sun’s surface can elicit such gasps from them. And a few of these students have not been outside a metropolitan area with all its light pollution. They have no idea how majestic the night sky is with the Milky Way visible.
