It follows that radioactive decay rates were much higher in the past.
In other words, when 'c' was higher, atomic clocks ticked more rapidly and 'atomic time' ran fast.
They would also take a figurative (non-literal) interpretation of the Genesis account of creation.
Creationism believes that the universe and all living organisms originate from the Creator God of the Bible.
Even in recent times, hundreds of measurements of 'c' since 1675 show a small but statistically significant decrease i.e. The Effect of Changes in 'c': It is well known that the radioactive decay 'constant' K can be changed i.e. In particular, Setterfield has shown that K is strongly related to 'c'.
So if the speed of light slows down, then the radioactive decay rate also slows down, link.
the Royal Society, which counts 21 Nobel Prize winners among its Fellows, claims that Creationism is unscientific and wrong and that evolution is right.
On this definition it is not necessary to assume an old earth and Young Earth (YE) Creationism is the belief that the universe and the Earth are just 6,000 to 10,000 years old as inferred from a literal interpretation of the Old Testament.
"Creationism appears to be virtually absent from the mainstream denomination churches such as Anglican, Catholic, Baptist Union, Methodist, United Reformed Church and the Church of Scotland" [British Centre for Science Education] Despite the scepticism of mainstream churches, Creation Science aims to provide scientific support for YE Creationism.
The discussion below suggests that this huge discrepancy in dating arises in the refusal of OE science to recognise the biblical Flood as a single, catastrophic worldwide event in recent history, and in the OE assumption of 'uniformitarianism'.
ACCELERATED NUCLEAR DECAY: Classical OE dating or radiometric dating is based upon the spontaneous breakdown or decay of atomic nuclei, where a radioactive parent atom decays to a stable daughter atom.
