Radiometric dating flaws

11 May

In this report, for example, we are told that using one radioactive dating technique, a lunar rock sample is 4,283 million years old, plus or minus 23 million years old.

In other words, there is a 95% certainty that the age is somewhere between 4,283 23 million years and 4,283 – 23 million years.

To date a radioactive rock, geologists first measure the “sand grains” in the top glass bowl (the parent radioisotope, such as uranium-238 or potassium-40).

During the race you have to watch the swimmer and count how many laps he has swum so you know that he has done 1,500 metres.Yet this view is based on a misunderstanding of how radiometric dating works.Part 1 (in the previous issue) explained how scientists observe unstable atoms changing into stable atoms in the present.A swimming race illustrates the simple principles involved in measuring time.This swimmer is competing in a 1,500 metre race and we have an accurate, calibrated wristwatch.
