Breakups, Move-Ins, and the Apartment Nobody Cleaned: Nuclear Fusion Explained

I’ve had to explain nuclear fusion a lot lately to people hearing about it for the first time. After a few tries that flopped, I think I found an analogy that works: loving couples, breakups, and what happens to their furniture. Stick with me. The short (but technical) answer: Fusion works by pushing two tiny atoms together until they merge into one. When they join, a small bit of mass turns into a huge burst of energy. This is the same reaction that powers the Sun. The hard part? Atoms push each other away, so you need insane heat and pressure to force them together. Now for my analogy.
