#2 Homer And His (Almost) God Particle
Amazingly it was our favorite neighborhood dummy who predicted this one. In another 1998 episode, Homer Simpson almost confirmed the Higgs boson (aka the God particle) years before the CERN themselves confirmed it in 2013.
In the episode “The Wizard of Evergreen Terrace,” Homer is solving an equation that turns out to be close to the Higgs boson. However, this isn’t surprising after learning that many Simpsons writers were mathematicians long before they joined the show.
