Abstract
THE uniform time of radioactive decay is identified by G. J. Whitrow with the t-time of kinematical relativity, according to which the ‘age of the universe’ is of the order 2 × 109 years. Since this is not the uniform time of dynamics, according to which the ‘age of the universe’ is infinite, a comparison is made between the dates assigned to various geological epochs by radioactive methods and the corresponding dates in dynamical time. It is found that the two measures of the whole fossil period differ by an amount not much greater than the probable error in estimating its duration by the present methods.
