But it is a known fact among scientists that such changes in decay rates can and do occur.
Spread before us would be a scene of fully grown plants and flowers. We would not, instead, see a barren landscape of seeds littering the ground.We would see full-grown chickens, not unhatched eggs.Rates are really statistical averages, not deterministic constants.The most fundamental of the initial assumptions is that all radioactive clocks, including carbon 14, have always had a constant decay rate that is unaffected by external influences—now and forever in the past.This is an important topic; for evolutionists want the history of earth to span long ages, in the hope that this will make the origin and evolution of life more likely.
Therefore we shall devote an entire chapter to a discussion of every significant method, used by scientists today, to date ancient substances.Sometimes, the radioactive chain may begin with an element partway down the decay chain.A somewhat different type of radioactive dating method is called carbon 14-dating or radiocarbon dating.It is based on the formation of radioactive elements of carbon, in the atmosphere by cosmic radiation, and their subsequent decay to the stable carbon isotope.We will also discuss radiocarbon dating in this chapter. Ideally, in order to do this, each specimen tested needs to have been sealed in a jar with thick lead walls for all its previous existence, supposedly millions of years!But in actual field conditions, there is no such thing as a closed system. It is impossible to know what was initially in a given piece of radioactive mineral.
