Therefore, there are several assumptions that must be made in radioisotope dating.
Three critical assumptions can affect the results during radioisotope dating: Radioisotope dating can be better understood using an illustration with an hourglass.
Radioisotope dating (also referred to as radiometric dating) is the process of estimating the age of rocks from the decay of their radioactive elements.
There are certain kinds of atoms in nature that are unstable and spontaneously change (decay) into other kinds of atoms.
That is, billion-year half-lives can be measured statistically in just hours of time.
The following table is a sample of different element half-lives.
For example, uranium will radioactively decay through a series of steps until it becomes the stable element lead. The original element is referred to as the parent element (in these cases uranium and potassium), and the end result is called the daughter element (lead and argon).
The straightforward reading of Scripture reveals that the days of creation () were literal days and that the earth is just thousands of years old and not billions.
There appears to be a fundamental conflict between the Bible and the reported ages given by radioisotope dating.
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.
If we walk into a room and observe an hourglass with sand at the top and sand at the bottom, we could calculate how long the hourglass has been running.
By estimating how fast the sand is falling and measuring the amount of sand at the bottom, we could calculate how much time has elapsed since the hourglass was turned over.
For example, the remaining radioactive parent material will decrease by 1/2 during the passage of each half-life (1→1/2→1/4→1/8→1/16, etc.).
