Radiometric dating proved wrong

If so, the data will fall on an isochron line, but will be all over the place.

This tells scientists that the sample has been disturbed and cannot be dated with this particular method.

Both of these are divided or normalized by a stable isotope of the same elements as the daughter element.

So on the x-axis, we have parent/(another stable isotope of the same element as the daughter) and on the y-axis we have daughter/(another stable isotope of the same element as the daughter).

A very common claim of young earth creationists in trying to reject the evidence for an old earth is to loudly proclaim that radiometric dating methods “makes assumptions” and that these “assumptions” are somehow fatally flawed or not supported by evidence.

These claims generally land in three different categories: (1) radiometric dating assumes that initial conditions (concentrations of mother and daughter nuclei) are known, (2) radiometric dating assumes that rocks are closed systems and (3) radiometric dating assumes that decay rates are constant.

Most young earth creationists reject all of these points.

As a scientific skeptics, we ask ourselves: is this really the case?

In a last ditch effort, young earth creationists exclaim that scientists just assume, without warrant, that decay rate are constant. Decay rates have been shown to be constant, despite very high pressure and temperature.Furthermore, by studying supernovas far away, scientist have determined that decay rates have been constant in the ancient past as well.Not only that, different radioactive isotopes decay differently and it is enormously improbable that a postulated difference in decay rates would affect all of them in the same way, yet as we have seen, different radiometric dating methods converge on the same date (within margins of error).There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods. There exists different versions, or isotopes of many elements.
