Christian perspective on radiometric dating
Beyond this, scientists have now used a "time machine" to prove that the half-lives of radioactive species were the same millions of years ago.
Most people accept the current old-earth (OE) age estimate of around 4.6 billion years.
Accepted Dating Methods Here we outline some dating methods, both absolute and relative, that are widely accepted and used by the scientific community.
Absolute dating supplies a numerical date whilst relative dating places events in time-sequence; both are scientifically useful.
Did you know that you can be a Christian, and believe that the earth is billions of years old?
You can even believe in evolution and be a Christian.
Their results consistently agree with an old Earth.
Over a thousand papers on radiometric dating were published in scientifically recognized journals in the last year, and hundreds of thousands of dates have been published in the last 50 years.
Radioactive parent (P) atoms decay to stable daughter (D) atoms e.g.
the carbon isotope C-14 decays to nitrogen-14 and the uranium isotope U-235 decays to the lead isotope Pb-207.
The time required for half the original number of parent atoms to decay is called the half life.
Essentially all of these strongly favor an old Earth.
Radioactive decay rates have been measured for over sixty years now for many of the decay clocks without any observed changes.
