Re: #49:

I suspect the time required for this to occur is quite long. The other "stable" isotopes (excluding iron) seem to exist in an extremely long lived metastable state. Maybe longer than the proton decay time?

Iron 56 is the stable isotope. Iron 60 has a half-life of 1.5 million years. If this event occured 2 million years ago there would still be a lot of it around. For comparison the half-life of Carbon 14 is 5730 years (yes, its that carbon 14).
