Abstract:

The top quark, discovered 20 years ago, is now copiously

produced at the CERN Large Hadron Collider, which allows detailed

studies and interpretations of its properties. It remains the

heaviest elementary particle ever found. Its strong interaction

properties are those of any

other quark, but its large coupling to the Higgs boson suggests a special

role in electroweak symmetry breaking. I review recent efforts to compute

top quark properties precisely, and discuss the more speculative

questions: Does the top quark, elusive as it is, determine the fate of the

Universe? Does naturalness require top partners, and what and where are

they?
