Re: A Look At The Age of The Earth.

Hi Frank,

Welcome back! I thought one means of measurement was that of Al26, turning into 
Mg26 its daughter isotope. This dating is based on the time it takes Mg26 to 
fully turn from one form to the other. The cause of the alteration is cosmic 
rays bombarding asteroid material and passing through it. Although I tend to 
accept the old age theory, what troubles me is how do we know that cosmic 
bombardment has always been the same frequency. Could it have been double, 
triple or even hundreds of folds more in the past. If so could there be error 
in the generally excepted age we now except? Of course the question is the same 
for all isotopes used in dating now a days. Could a super nova or nova event 
gives us the wrong sense of time?

This is a pretty rough question that was asked without digging into my library 
so would appreciate everyone excepting my drift even though I might be off on 
the particulars.

By the way, would enjoy hearing of your adventures if you would care to share 
them with us here. Did you do any meteorite hunting? Did you go and see any 
collections.?
