I’m always taken back by the waste of sheer effort that YEC put into some of these papers, akin to writing fan dissertations on the geology of Middle Earth.
The inescapable heat problem of YEC is you cannot have energy and not energy. They, not anyone else, are the ones insisting on all this high energy catastrophe. Heat, and prodigious amounts of it, are essential to the processes they conjecture in order to squeeze epochal processes into the compass of the one year flood.
Heat is not some side effect of radioactivity. Spontaneous decay is always in the direction of lessor mass, and that difference does not vanish; it must manifest as energy. You cannot have accelerated nuclear decay without accelerated thermal catastrophe.
Heat of enthalpy is likewise inherent - you cannot have exothermic formation of the earth’s biogenic limestone without the oceans scalding. Likewise, you cannot have screaming velocity tectonic plates without melting them.
The earth orbits in the vacuum of space, so all YEC proposed convective mechanisms of heat removal are hogwash. Ultimately, the global heat must be radiated.
The only physically plausible solution to the YEC heat problem is to allow that these processes did not happen.
