So, the fatal problem with all radioactive dates is that they are all based on assumptions about the past.
You can get any date you like depending on the assumptions you make.
But they don’t discuss the basic flaw in the method: you cannot determine the age of a rock using radioactive dating because no-one was present to measure the radioactive elements when the rock formed and no-one monitored the way those elements changed over its entire geological history.
The educational page hosted by the US Geological Society provides one recent example of the way radioactive dating is explained to the public.
And radioactive dating is so shrouded with mystery that many don’t even try to understand how the method works; they just believe it must be right.
But the basic concept of radioactive dating, sometimes called radiometric dating, is not difficult, especially since all of us regularly calculate how much time has passed: for example, since our birth, or since we started on a walk.
The fact is that you can only establish the time for the race if it was timed by two or more reliable eyewitnesses who observed the you cannot measure the age of a rock using radioactive dating because no-one was present to measure the radioactive elements when the rock formed and no-one monitored the way those elements changed over its entire geological history This illustrates the problem with the radioactive dating of geological events.
Those who promote the reliability of the method spend a lot of time impressing you with the technical details of radioactive decay, half-lives, mass-spectroscopes, etc.
but don’t even mention the fact that we can’t measure the concentrations of isotopes in the past.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.And you have to check to make sure he touches the end for each lap.These viking women are the enigma wrapped in a conundrum because the men still haven’t figured them out.
