Using our state-of-the-art code Fornax we have simulated the collapse and explosion of the cores of many massive-star models in three spatial dimensions. This is the most comprehensive set of realistic 3D
core-collapse supernova simulations yet performed and has provided very important insights into the mechanism and character of this 50-year-old astrophysical puzzle. Most of our 3D models explode naturally and understandably, given detailed initial model progenitors inherited from others. I will present results from this suite of runs and the novel conclusions derived from our new capacity to simulate many 3D, as opposed
to 2D and 1D, full physics models every year. The results collectively suggest that the qualitative resolution of this recalcitrant, multi-decade, enigma may be within sight.
