The title of this talk remains one of the most important
and challenging questions in theoretical astrophysics. The explosive
deaths of massive stars, core-collapse supernovae, are some of the most
energetic events in the Universe; they herald the birth of neutron stars
and black holes, are a major site for nucleosynthesis, influence
galactic hydrodynamics, trigger further star formation, and are
prodigious emitters of neutrinos and gravitational waves. Though these
explosions play an important and multifaceted role in many cosmic
phenomena, the details of the explosion mechanism have remained elusive
for many decades. The fundamental challenge of core-collapse theory is
to understand what makes the difference between a fizzled result and
successful explosions. Ultimately, answering this question will require
both theory and observational constraints. In this talk, I will present
a unifying theory for core-collapse supernova explosions, and I will
present our observational constraints on which stars actually explode.
