Relife edin cam sex - Carbon dating false assumptions

The initial conditions are just read off the graph; it is not just assumed.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.There are many different kinds of radiometric dating and not all conclusions we will reach can be extrapolated to all methods used.

This means that the while different rocks contain different absolute amounts of the two isotopes, the is same.

At the time of formation for a rock, the isotopes for an element are homogenized and so the composition of a certain isotope is the same in all the minerals in the rock.

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.

Let us critically examine each of these claims and see if they hold up against the science.

While doing so, we will have to learn about how radiometric dating works.

This serves as strong evidence for the reliability of radiometric dating methods. These isotopes differ in the number of neutrons they have in their nuclei.

Those isotopes that are not stable decay into daughter nuclei.

That is, you can see if the sample comes from rocks that have been disturbed (or contaminated) or not just by looking at the results.

Now, creationists will claim that scientists are just somehow assuming that if samples show an age that does not fit their preconceptions, the sample must be contaminated or leaky. To see why, we need to look deeper into radiometric dating methods.

A very important tool in radiometric dating is the so called isochron diagram and it holds the key to refuting the central creationist claims about radiometric dating.
