Isochron radiometric dating new thread
This is the same as the initial amount (it would not change if there were no parent isotope to decay).Figures 4 and 5, and the accompanying explanation, tell how this is done most of the time. I know your not interested in debating, you just want to say "haha I'm right" but I figured I might as well post this for anyone who is seriously interested in the answer.Those claims have been made in many places (not all), but have never been upheld.
But half-lifes are observable by astronomers, as stated by Rren above. There are no arguments about this sort of thing in scientific communities as the conclusions have been independently reproduced, and the data always fits.
Now if you can show me that the starting amounts of parent and daughter product are measured, then this is over. I'm sorry my friend, but all you are providing is some "hot-air". We know what the parent nucleus contained because we can look back in time, way out in space and observe what things looked like billions of years back. If you think you have some, please post links instead of argumentative hogwash. The ratio of the two atom types is a direct function of its age because when the rock was formed, it had all parent atoms and no daughters.
I'm sorry that the vast amount of data accepted by the scientific community isn't good enough for you. Decay rates have been directly measured over the last 40-100 years. These elements could have floated around in the universe for billions of years before forming earth. or The daughter could also have been created at the same time as the parent. Until you can prove with science, the below quote, then the dating method is not valid. Now is when you go back into your little tirade and scream and shout that you supplied the information.
Usually it involves using more than one sample from a given rock.
It is done by comparing the ratios of parent and daughter isotopes relative to a stable isotope for samples with different relative amounts of the parent isotope.Your water glass analogy is simplistic and innacurate.
