Proponents of evolution publicize radioisotope dating as a reliable and consistent method for obtaining absolute ages of rocks and the age of the earth.
This apparent consistency in textbooks and the media has convinced many Christians to accept an old earth (4.6 billion years old).
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.
Types of igneous rocks include granite and basalt (lava).
Sedimentary rocks, which contain most of the world’s fossils, are not commonly used in 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.These types of rocks are comprised of particles from many preexisting rocks which were transported (mostly by water) and redeposited somewhere else. Atomic mass is the heaviness of an atom when compared to hydrogen, which is assigned the value of one. In beta decay, either an electron is lost and a neutron is converted into a proton (beta minus decay) or an electron is added and a proton is converted into a neutron (beta plus decay).Types of sedimentary rocks include sandstone, shale, and limestone. In beta decay the total atomic mass does not change significantly.Once the rock cools it is assumed that no more atoms can escape and any daughter element found in a rock will be the result of radioactive decay.The dating process then requires measuring how much daughter element is in a rock sample and knowing the decay rate (i.e., how long it takes the parent element to decay into the daughter element—uranium into lead or potassium into argon). Half-life is defined as the length of time it takes half of the remaining atoms of a radioactive parent element to decay.Since we did not observe the initial conditions when the hourglass time started, we must make assumptions.All three of these assumptions can affect our time calculations.Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline.Mike Riddle exposes the unbiblical assumptions used in these calculations The primary dating method scientists use for determining the age of the earth is radioisotope dating.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.
