When I was in high

When I was in high school, I gave a presentation on black holes, wormholes and time travel for my physics class. There weren’t many people in the class who had ever heard of wormholes and the like, but it was neat to see people who normally wouldn’t be interested in such things asking questions about it and trying to get their minds around 4-dimensional spacetime. I wanted to scream at them: “See, science *is* fun and interesting!”
