Uranium thorium radiometric dating

The basic theory of radiometric dating is briefly reviewed.Since 1955 the estimate for the age of the Earth has been based on the assumption that certain meteorite lead isotope ratios are equivalent to the primordial lead isotope ratios on Earth.It has become increasingly clear that these radiometric dating techniques agree with each other and as a whole, present a coherent picture in which the Earth was created a very long time ago.Further evidence comes from the complete agreement between radiometric dates and other dating methods such as counting tree rings or glacier ice core layers.

And since this favored 'date' is the only one that's trumpeted by the media it is the only date that many assume to be correct.Without nuclei, we simply would not exist, and it is important to understand why!NUPEX provides a free database of knowledge, created and maintained by expert nuclear physicists from all over Europe.There are many ways to keep track of time, the most reliable of which is to use actual records such as counting hours, days, weeks, and years.However, when we speak of the distant past, there are no historical records and thus no verifiable way to prove that a certain 'date' is correct.
