Radiometric dating encyclopedia nokia updating tool
Radiometric dating is based on the decay rate of these isotopes into stable nonradioactive isotopes.
To date an object, scientists measure the quantity of parent and daughter isotope in a sample, and use the atomic decay rate to determine its possible age.
One possibility for the accelerated decay comes with the possibility of variable speed of light.
Other theories simply hypothesize that during certain periods of time God sped up the process; these are called singularities in creation science.
Other methods such as Potassium-argon dating and Isochron dating are based on faulty assumptions and so unreliable as to be useless.
Many atoms (or elements) exist as numerous varieties called isotopes, some of which are radioactive, meaning they decay over time by losing particles.
However, these fossils are not problematic if one simply disregards their existence.
If the date generated by isotope dating analysis agrees with the conventional interpretation of the geological column, paleontologists will accept it as valid.
Earth sciences - Radiometric dating In 1905, shortly after the discovery of radioactivity, the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead.… continue reading »
