Core-collapse supernovae from massive stars are among the most

energetic events in the universe. They liberate a mass-energy

equivalent of ~15% of a solar mass in the collapse of their progenitor

star's core. The majority (~99%) of this energy is carried away by

neutrinos, while (~1%) is transferred to the kinetic energy of the

explosive outflow.  A smaller, yet still tremendous amount of energy

is emitted in electromagnetic and gravitational waves.

The stellar collapse phenomenon and its range of outcomes pose a

formidable challenge to computational modeling. I discuss this

challenge and review recent progress made in the multi-dimensional

modeling of the physical mechanism(s) believed responsible for

converting the gravitational energy liberated in collapse into energy

of the explosion. I outline how detections of gravitational waves and

neutrinos from the next nearby core-collapse event can help to

observationally probe dynamics and thermodynamics of the supernova
