### How reliable is radiometric dating?

The reliability of radiometric dating is subject to three unprovable assumptions that every geologist must make when using the radioactive “clock”. Radioactive rocks offer a similar “clock.” Radioactive atoms, such as uranium (the parent isotopes), decay into stable atoms, such as lead (the daughter isotopes), at a measurable rate.

### What is radiometric parent to daughter dating?

There are many different radiometric dating methods used in science to determine the age of rocks and minerals. Each radiometric Parent to Daughter has various constraints and limitations. Generally, the researcher’s dating method is based on the available rocks and minerals that can be tested.

### What are the assumptions of radioactive dating?

The assumptions on which the radioactive dating is based are not only unprovable but plagued with problems. As this article has illustrated, rocks may have inherited parent and daughter isotopes from their sources, or they may have been contaminated when they moved through other rocks to their current locations.

### How does radiometric dating prove the age of the Earth?

Radiometric dating techniques are touted as the final proof that the earth is billions of years old. However, a closer look reveals that radiometric dating is driven by subjective presumptions made by the researcher. These presumptions allow the study to conclude any date expected or desired simply by the adjustment of variables or presumptions.

### Can all radiometric dating methods be wrong?

In regard to the radiometric dating of rocks, it is known that various different radiometric methods often yield quite discordant dates for the same rock, thus proving that they cannot all be correct.

### What is the most common radiometric dating method for uranium?

One common radiometric dating method is the Uranium-Lead method. This involves uranium isotopes with an atomic mass of 238. This is the most common form of uranium.

### Why do scientists reject all but the oldest dating methods?

Yet when asked why they reject all but the oldest science-based dating methods, the answer often given is that (they think) long-age radiometric dating is more reliable and that science settled the matter of the earth’s age many years ago.

### How is radiometric dating used to date fossils?

Radiometric dating is based on the half-lives of the radioactive isotopes. These half-lives have been measured over the last 40-90 years. They are not calibrated by fossils.

### How is the age of the Earth determined?

The same techniques of radiometric dating have been used on those rocks. All the data from Earth and beyond has led to the estimated age of 4.5 billion years for our planet. The age of rocks is determined by radiometric dating, which looks at the proportion of two different isotopes in a sample.

### Does radiometric dating prove millions of years old?

Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline. Mike Riddle exposes the unbiblical assumptions used in these calculations. The presupposition of long ages is an icon and foundational to the evolutionary model.

### Does radioisotope dating prove the oldest Earth?

Proponents of evolution publicize radioisotope dating as a reliable and consistent method for obtaining absolute ages of rocks and the age of the earth. This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).

### What are radioactive elements used for in radiometric dating?

In radiometric dating, the measured ratio of certain radioactive elements is used as a proxy for age. Radioactive elements are atoms that are unstable; they spontaneously change into other types of atoms. For example, potassium-40 is radioactive.
