The dating game

Hi, Reserve! Welcome! That first part is nearly true, but there's a variation of potassium-argon dating, called argon-argon, that's been used to date the Pompeii-burying eruption of Vesuvius. That was in 79AD, by historical and tree-ring dates, and argon-argon got it right with an error of +/- 94 years. There, but you must register for free to read it.Here's the abstract:

39 years old, and the abstract says (my emphasis) 39 years old, and the title says Reserve, do you think the authors were complete morons, or perhaps is it your source being less than forthright with what they know?

Technetium is present in some Red Giant stars that are actively dredging up material from their interiors - where fresh technetium is being synthesized by nuclear reactions. Googling "solar technetium" turns up some very old references that raise the possibility of some in the Sun, but more, later references that say probably the spectral lines are misassigned. The Moon doesn't seem to have any.Some Cretinists claim the the "accelerated nuclear decay" was during their Creation Week - so they will just say that the Sun and Moon were made without Tc or were subject to accelerated decay as well.
