Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering—the reason Jesus came into the world (See Six Days? He said, This only makes sense with a time-line beginning with the creation week thousands of years ago.It makes no sense at all if man appeared at the end of billions of years.The energies involved are so large, and the nucleus is so small that physical conditions in the Earth (i.e. The rate of decay or rate of change of the number N of particles is proportional to the number present at any time, i.e.The half-life is the amount of time it takes for one half of the initial amount of the parent, radioactive isotope, to decay to the daughter isotope.We will deal with carbon dating first and then with the other dating methods.Carbon has unique properties that are essential for life on Earth.In 1897, French physicist Henri Becquerel left some uranium salts on a photographic plate as part of some research on how light influenced these salts.To his surprise, the plate fogged up, indicating some sort of emissions from the uranium salts.
However, use of a single decay scheme (usually Pb) leads to the U–Pb isochron dating method, analogous to the rubidium-strontium dating method.
Uranium is naturally radioactive: Its nucleus is unstable, so the element is in a constant state of decay, seeking a more stable arrangement.
In fact, uranium was the element that made the discovery of radioactivity possible.
Thus the current ratio of lead to uranium in the mineral can be used to determine its age.
The method relies on two separate decay chains, the uranium series from Pb) leads to multiple dating techniques within the overall U–Pb system.
