Hodge conjecture
Hodge's Conjecture, or (The) Hodge Conjecture, also known as "Hodge's Letter-A Problem," or Hodge's Letter, is a Millennium Problem and a meme, and one whose expression has grown in length and complexity over the years, being seen generally a "problem of diversion," but not a "problem-problem." Hodge's Letter may help the world understand more about algebra topology, and how long straight-lines meet.
