yeah thats cool, but lets take CARBON DATING for example. did you know that its been proven wrong. Carbon is affected by temperature, climate,weather, and germs. on the other hand Isotopes are more consistant. now if we use that for dating we find that the fossils arent as old as we are taought that it is.
Carbon dating uses the
isotope of carbon --Carbon 14. Most carbon is carbon 12 -- 6 protons and 6 neutrons in the nucleus. Carbon 14 has 6 protons and 8 neutrons. It decays by giving off a beta particle and converting one of the neutrons to a proton, becoming nitrogen in the process.
Now, carbon dating uses the fact that living organism take in carbon during their lifetime --both C12 and C14. When they die, this stops. Thus, they stop taking in C14 and the C14 isotope decays. Half of it decays in 5,750 years, half of what remains decays in another 5,750 years, half of what is left in another 5,750 years, etc. So by 57,500 only 1/2048 is left. At this point the amount of C14 is too low for us to detect. So we do
not date fossils by this method. It doesn't go back far enough.
Now, every method has limitations. Within the limitations, C14 dating is accurate. It has been calibrated by comparison to historical events and tree rings.
Now, you quoted Gentry. First, Gentry
is a Christian scientist,and a creationist. Why your source would want to lie about that is beyond me. Second, you are talking about polonium halos, not C14.
>sacondary polonium halos AKA Radio Halos(dirived from the decaying of uranium)
>for coal to form, exact conditions must be met.
>When wood is buried water infiltrates it.then uranium enters it as well.
>the wood is then compressed(coal doesn't compress. it shaters).this evidence points to a simultaneus event.
>when Uranium entered the wood it left some of its decayed product(lead)
>uranium and lead therfore should decay in uniform.
This makes no sense. Uranium and the radioactive isotopes decay at different rates.
> as the lead and uranium decay the ratio down
>In coal gathered in mines in the Colorado Plateau(believed to be of TRIASSIC age).
"the ratio between 238U and 206Pb should be low; instead some such halos have been found with uranium-lead ratios ranging from about 2,200 to over 64,000. meaning that currently accepted ages may be too high by a factor of 10,000, admitting the possibility that the ages of the wood are to be measured in millenia."

>this information has remained uncllenged and unreputed by the scientific cummunity since it was published in 1976.
>these results pertain to the simultaneus buriul of the Eocene,60 MY ago, the cretaceuos, 110 MY ago, the Jurassic, 160 MY ago and triasic, 225 MY ago.
>this goes for the origin and age of coal wherever it is found.
>as you can see the earth is only a few 1000 years old.
Gentry, unfortunately, refuted it himself. He admitted, under oath in the 1982 Arkansas trial, that he falsified his results. It's unfortunate that your source only put out the 1976 claim and not Gentry's 1982 retraction.
We have been discussing C14 dating in another thread. Here, go thru this site -- all the pages -- and you will get an education in carbon dating:
