To illustrate, suppose there is a burning candle sitting on the table. This can be calculated if the candles burn rate and original length is known.However, if the original length is not known, or if it cannot be verified that the burning rate has been constant, it is impossible to tell for sure how long the candle was burning.The most commonly used radiometric dating methods are potassium-argon, uranium-lead, and rubidium-strontium. Half-life is simply the time required for half of the atoms in a pound of uranium, for example, to disintegrate into lead.
Since God is the Creator of all things (including science), and His Word is true (“), the true age of the earth must agree with His Word.
A similar problem occurs with radiometric dating of rocks.
Since the initial physical state of the rock is unknowable, the age can only be estimated according to certain assumptions.
After a prologue by John Morris, Larry Vardiman introduces the RATE Project, for which the book is only a preliminary summary.
Don De Young, in chapter 2, summarises the radioactive decay equation, the main dating methods, their major assumptions, and their major problems.
