Radiometric dating of dinosaur fossils

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 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.

Many people assume that the dates scientists quote of millions of years are as reliable as our knowledge of the structure of the atom or nuclear power.

A swimming race is a familiar situation that illustrates the simple principles involved in measuring time.

And you have to check to make sure he touches the end for each lap.

Without these observations you cannot be sure that the time is valid.

You could describe the atomic workings of the quartz oscillator and how it resonates at a specific and highly stable frequency, and how this is used to accurately pace a timekeeping mechanism.

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.
