As I said earlier, my son is a Nuke on a US Navy submarine. If the decay rate of the uranium in their reactor core changes substantially, they’re probably all dead meat. If it slows down, they left without power. If it speeds up, it will melt the containment. On what basis do we trust the lives of those sailors to the assumption that decay rate is and will remain constant?
Another in a long line of evos who didn’t bother to read the article but just knee jerks his way through the postings.
The point was that during one or two cataclysmic events, it’s possible that the decay rate changed, at that time, not that it is variable.
It’s been constant for the how many hundred years that we’ve know about radioactive decay and anything using radioactivity is based on what we’ve seen for that couple hundred years or so.
The technology works now based on the radioactive decay now.
It would still render dating results erroneous if the the decay rate changed at one point in time.
