People would bring up the heat problem but I had answers for them as well.
You haven't posted any answers to the heat and radiation problems 'round here. This thread isn't the place for it, but you should definitely start a thread on radiometric dating. Maybe I will.
I got around that by saying that all the physical constants changed in tandem in such a way that no physical manifestation would show.
Just sayin' it doesn't do. As I've pointed out many times, the trick is to
show a set of changes to various physical constants that
do show a physical manifestation (accelerated decay)
and are not refuted by existing observations. Setterfield's been trying to do it for decades and hasn't succeeded.
