If the calculated result gives an acceptable age, the investigators publish it.
Examples of ages listed here are also obtained by applying the same principle of uniformitarianism.
the age of the earth and the universe, and that includes the ones we have listed here.
Although age indicators are called ‘clocks’ they aren’t, because all ages result from calculations that necessarily involve making assumptions about the past.
However, to draw this conclusion we have to assume that the rate of cratering has been the same in the past as it is now.
And there are now good reasons for thinking that it might have been quite intense in the past, in which case the craters do not indicate an old age at all (see below).
It only speaks of ways in which DNA is damaged in living cells - (which fossils are clearly not).
Such is the nature of science, especially historical science, because we cannot do experiments on past events (see “It’s not science”).
Science is based on observation, and the only reliable means of telling the age of anything is by the testimony of a reliable witness who observed the events.
The assumptions behind the evidences presented here cannot be proved, but the fact that such a wide range of different phenomena all much younger ages than are currently generally accepted, provides a strong case for questioning those accepted ages (currently 13.77 billion years for the universe and 4.543 billion years for the solar system).
Also, a number of the evidences, rather than giving any estimate of age, challenge the assumption of slow-and-gradual uniformitarianism, upon which all deep-time dating methods depend.Always the starting time of the ‘clock’ has to be assumed as well as the way in which the speed of the clock has varied over time.
