Diverse

 I would argue that there is a level in mathematics called the "Genius Level Gap" that separates already extremely difficult mathematics from the genius level.

After a breakup, there are some concepts that are really hard for me to understand in my entire life, and only a few people can handle them. I'm talking about things like homological mirror symmetry, complex Kleinian groups, perfectoid spaces, Fermat's Last Theorem, the Poincaré conjecture, and so on. The evidence is the result of years of research involving the best minds on the planet.
