One of the biggest puzzles in elementary physics is why the Universe seems to contain so much more matter than antimatter.  Our current understanding of elementary particles treats matter and antimatter in nearly the same way, and is unable to explain the observed asymmetry.  In this talk I will explain the source of the puzzle in more detail, and I will describe some of the ways in which it might be solved.  I will also comment on how these proposed explanations might lead to new and unusual signals in current and upcoming particle collider experiments and astrophysical observations.
