Bristlecone pine carbon dating

A slow-growing pine, Pinus aristata, native to the western United States.

As a tree physiologist I would say that evidence of false rings in surely counts much more strongly against such the notion.Most carbon atoms have six protons and six neutrons in their nuclei and are called carbon 12.But a tiny percentage of carbon is made of carbon 14, or radiocarbon, which has six protons and eight neutrons and is not stable: half of any sample of it decays into other atoms after 5,700 years.His dendrochronological studies spanned almost thirty years, of which the last five were spent mostly in the White Mountains.Through the study of annual growth rings of these trees, a fairly precise method of absolute dating has been obtained.Nyerup's words illustrate poignantly the critical power and importance of dating; to order time.
