Core-Collapse Supernovae are some of the most energetic phenomena in the modern universe. They rival their parent galaxy in visual brightness, however, this is only a small fraction of the total energy released. Most of the gravitationally energy released during the core collapse is converted to neutrinos. These neutrinos and their effect on the supernova central energy drive most of the dynamics associated with garden variety core-collapse supernovae. In this talk, I will sketch out the theory of core-collapse supernovae, give a summary and update of the state-of-the-art research into understanding the explosion mechanism, and present some predictions on what the expected neutrino signal in Earth-based detectors will be and what it can tell us about the progenitor stars. If time permits, I'll discuss the outcome of failed supernova.
