The Remarkable Metrological History of Radiocarbon Dating [II]

The radiocarbon clock has become an extremely useful and efficient tool in dating the important episodes in the recent prehistory and history of man, but because of the relatively short half-life of carbon-14, the clock can be used for dating events that have taken place only within the past 50,000 years.

Thus, radiocarbon dating is only useful for measuring things that were formed in the relatively recent geologic past. Luckily, there are methods, such as the commonly used potassium-argon (K-Ar) method, that allows dating of materials that are beyond the limit of radiocarbon dating (Table 1).

Discussions about the age of the Earth don’t do anything to disprove the Bible, because the Bible says nothing explicit about the age of the Earth. However, geologists, palaeontologists and astrophysicists have plenty to say about the manner in which the universe, the solar system and the Earth were created.
