Core-collapse theory brings together many facets of high-energy and nuclear astrophysics and the numerical arts to present theorists with one of the most important, yet frustrating, astronomical questions: "What is the mechanism of core-collapse supernova explosions?" A review of all the physics and the fifty-year history involved would soon bury the reader in minutiae that could easily obscure the essential elements of the phenomenon, as we understand it today. Moreover, much remains to be discovered and explained, and a complicated review of an unresolved subject in flux could grow stale fast. Therefore, in this paper I describe what I think are various important facts and perspectives that may have escaped the attention of those interested in this puzzle. Furthermore, I attempt to describe the modern theory's physical underpinnings and briefly summarize the current state of play. In the process, I identify a few myths (as I see them) that have crept into modern discourse. However, there is much more to do and humility in the face of this age-old challenge is clearly the most prudent stance as we seek its eventual resolution.

A TWO-PARAMETER CRITERION FOR CLASSIFYING THE EXPLODABILITY OF MASSIVE STARS BY THE NEUTRINO-DRIVEN MECHANISM (2015, background): “…to 2D calculations or even no explosions (e.g., Hanke et al. 2012, 2013; Tamborra et al. 2014; Mezzacappa et al. 2015; Couch 2013; Couch & O’Connor 2014; Takiwaki et al. 2014) although some studies have proclaimed the opposite behavior (Nordhaus et al. 2010; Burrows 2013; Dolence et al. 2013).”
The Origin of Elements from Carbon to Uranium (2020, background): “…a few groups have presented multidimensional simulations of exploding 10–25Me stars (Marek & Janka 2009; Kotake et al. 2012; Bruenn et al. 2013; Burrows 2013), the explosion mechanism of corecollapse (Type II, Ib, and Ic) supernovae is still uncertain; the ejected iron mass in explosion…”
Nucleosynthesis in Stars and the Chemical Enrichment of Galaxies (2013, background): “The mechanism of transformation from collapse to explosion is not fully understood (e.g., Janka 2012, Kotake et al. 2012, Bruenn et al. 2013, Burrows 2013).”
Characterizing the Gravitational Wave Signal from Core-collapse Supernovae (2018, background): “…observation of GWs, neutrinos, and photons (Nakamura et al. 2016) from the next Galactic CCSN could unveil the mechanism by which massive stars explode at the end of their lives, resolving a puzzle that has eluded the scientific community for more than 50 yr (Janka 2012; Burrows 2013; Müller 2016).”
Supernova simulations from a 3D progenitor model - Impact of perturbations and evolution of explosion properties (2017, background): “`,m(θ, ϕ) = Y`,m(θ, ϕ)) with the same normalisation as in Burrows (2013) (see their Equation 2).”
A successful 3D core-collapse supernova explosion model (2018, neutral): “H E ] 1 3 Se p Burrows (2013), Müller (2016), and Janka et al. (2016).”
Merging black hole binaries: the effects of progenitor's metallicity, mass-loss rate and Eddington factor (2017, background): “In particular, it is crucial to assess what are the conditions for a star to directly collapse into a BH, without an explosion (e.g. Bethe 1990; Fryer 1999; Fryer et al. 2001; Janka et al. 2007; O’Connor & Ott 2011; Janka 2012; Burrows 2013; Ertl et al. 2016).”
Non-Radial Instabilities and Progenitor Asphericities in Core-Collapse Supernovae (2014, background): “On the one hand, it can be argued that turbulent stresses (Murphy, Dolence & Burrows 2013; Müller, Janka & Heger 2012; Couch & Ott 2014), heating by secondary shocks during the non-linear SASI phase (Müller, Janka & Heger 2012) and convective energy transport alter the (spherically averaged)…”
The mass spectrum of compact remnants from the parsec stellar evolution tracks (2015, methodology): “Several authors (e.g. Bethe 1990; Janka et al. 2007; Janka 2012; Burrows 2013) investigate for which structural properties of the progenitor star a SN can fail, leading to the direct collapse of the star to a BH.”
Revisiting Supernova 1987A constraints on dark photons (2016, methodology): “In this work we rely on the standard neutrino-induced explosion picture and refer the reader to [40, 43] for more discussion.”
