Re: No such thing as "too old" rocks for K/Ar dating

That's the one pirates use, right?

Only for a vast set of old rocks

Re: Half-life questions

Hi LindaLou,

Great, thanks. I'm better with astronomy -- nuclear physics was never my strong point!

Note the reference in the link to SN1987A, a rather unique nova event that allows us to measure the actual distance to the star ... and the information on cobalt decay during the nova.

You may also want to check out Are Uranium Halos the best evidence of (a) an old earth AND (b) constant physics?

Say hi to CTD for me, and remind him that half a half-life is not a quarter-life.
