Ah...I figured out what you were trying to say, but it seems that you were the one who missed the point. Not a single person has claimed that decay rates aren't assumed constant. That said, we believe that it is a valid assumption because dates obtained using those assumed constant decay rates correlate with each other despite different rates of decay from each isotope and they also correlate with non-radiometric dating techniques. I agree that it's a flaw since no assumption can ever be 100% certain, but in my experience, this one is pretty darn close.I did, you really should be careful about posting short sighted replies. For any decay...gaining or losing elements to have occured as we nnow know and measure it, we need out laws in place. Point...meet Rocksinmyhead.
You also say that "present state" is assumed - not sure what you mean here since the present state is observable. If we can't observe the present, then what good is science at all?
