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.

However, in doing so, we have, consciously or subconsciously, made a number of assumptions about other factors that could have affected the calculations.

Unless these factors are known, the calculated dates will not be reliable.

The procedure, however, is difficult, and many tests have shown that it can be inaccurate, and it is at times not even considered reliable by mainstream scientists.

It is impossible to measure the age of something, except to time it as it actually occurs, so radioactive dating methods calculate the age, based on (i) measurements of quantities of specified materials, (ii) measurements of decay rates, and (iii) assumptions about the history of the sample.

Y."; also see discussions by advanced equipment, 'memory effects' can be a problem with very young samples (Dalrymple, 1969, p. That is, very tiny amounts of argon contaminants from previous analyses may remain within the equipment, which precludes accurate dates for very young samples.

In some cases, the latter ratio appears to be a much more accurate gauge of age than the customary method of carbon dating, the scientists said.Since 1947, scientists have reckoned the ages of many old objects by measuring the amounts of radioactive carbon they contain.New research shows, however, that some estimates based on carbon may have erred by thousands of years.We could measure (a) how much water the tank holds, (b) how much is still in the tank, and (c) the rate at which it is leaking out.

We can calculate the age of the hole by subtracting (b) from (a) to find out how much water has left the tank, and then dividing this by (c), the rate at which it is leaking out.

Radioactive dating is the procedure of calculating an age for an artifact by determining how much of the radioactive material has decayed and calculating how long that would take given the half-life (how long it takes for half the material to decay) of the material being tested.
