How do we know radiometric dating is reliable

Every element is defined by the particular number of protons, neutrons, and electrons that make up it's atoms. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. The fact that dating techniques most often agree with each other is why scientists tend to trust them in the first place.

Answers to Creationist Attacks on Carbon Dating

Essentially all of these strongly favor an old Earth. The mathematics for determining the ages from the observations is relatively simple. Therefore, any C dates taken from objects of that time period would be too high.

From radiocarbon dates taken from bristlecone pines. Thus it can be demonstrated that the magnetic field of the earth has reversed itself dozens of times throughout earth history. Creationists such as Cook claim that cosmic radiation is now forming C in the atmosphere about one and one-third times faster than it is decaying. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters. 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.

To date a rock one must know the original amount of the parent element. They can then look at a single mineral, and using an instrument called a mass spectrometer, they can measure the amount of parent and the amount of daughter in that mineral. One such assumption was that the megalith builders of western Europe learned the idea of megaliths from the Near-Eastern civilizations.

Thus, a freshly killed mussel has far less C than a freshly killed something else, which is why the C dating method makes freshwater mussels seem older than they really are. If they are right, this means all C ages greater than two or three thousand years need to be lowered drastically and that the earth can be no older than ten thousand years.

All radioactive isotopes have a characteristic half-life the amount of time that it takes for one half of the original number of atoms of that isotope to decay. Additionally, lavas of historically known ages have been correctly dated even using methods with long half-lives. Well over forty different radiometric dating methods are in use, and a number of non-radiogenic methods not even mentioned here.

From careful physics and chemistry experiments, we know that parents turn into daughters at a very consistent, predictable rate. Scientists can measure the ratio of the parent isotopes compared to the converted isotopes. It does discredit the C dating of freshwater mussels, but that's about all. Most estimates of the age of the earth come from dating meteorites that have fallen to Earth because we think that they formed in our solar nebula very close to the time that the earth formed.

Well over forty different

These half-lives have been measured over the last years. Their results consistently agree with an old Earth. This is the same as the initial amount it would not change if there were no parent isotope to decay. And it has been close to a hundred years since the uranium decay rate was first determined.

All radioactive isotopes have a
