Other factors and basic assumptions must also be considered.Of course, Kelvin formed his estimates of the age of the Sun without the knowledge of fusion as the true energy source of the Sun.Free 5-day trial Radiometric dating is used to estimate the age of rocks and other objects based on the fixed decay rate of radioactive isotopes.

His Ph D thesis was on isotope ratios in meteorites, including surface exposure dating.Both the physical geologists and paleontologists could point to evidence that much more time was needed to produce what they saw in the stratigraphic and fossil records.As one answer to his critics, Kelvin produced a completely independent estimate -- this time for the age of the Sun.Today, with the help of isotopic dating methods, we can determine the ages of rocks nearly as well as we map the rocks themselves.For that we can thank radioactivity, discovered at the turn of the last century.
