These are established by a variety of elements, including but not limited to: the quality of the sample, the quality of the lab, and the age of the sample.

    It is when a sample is measured that the real complications begin: as the process to assign a meaningful date to the scientific chronology is rather erudite. dates (raw dates that are calibrated to the same calendar system are written without capital letters as b.c./ a.d. Younger samples have a larger margin of error than older samples.

    Dates could be assigned based upon scientific evidence rather than on the inconsistent mathematics, historical comparisons and simulated typologies of artifacts that had previously regulated time.

    And samples must be collected carefully, as often they have been in stable environments prior to their unearthing by industrious archaeologists and may be easily degraded in the open air or attacked by moisture and sunlight once gathered.
