[quote:Daniel's Seventieth Seven 1071051:MV8xODg2MzEzXzMxNTA0NDg5XzU0Nzk4Njkx] . [i]If a large cosmic-ray bombardment impacted the earth and irradiated the prehistoric landscape with thermal neutrons, the 235 U/238 U ratio would be changed; 239 Pu would be produced from neutron capture on 238 U, followed by the decay of 239 U. Neutrons colliding with nitrogen (1.83 barns) would create 14 C in exactly the same way 14 C is normally produced in the upper atmosphere,[b] necessarily resetting the radiocarbon dates of any organic materials lying near the surface on the North American prehistoric landscape[/b]—including charcoals at Paleoindian sites—to younger values. 239 Pu produced during the bombardment will also be partly destroyed by thermal neutrons with 1017 barn cross section. Assuming 239 Pu doesn’t mobilize, it will decay back to 235 U (half-life 24,110 yr), partially restoring the normal abundance.[/i] http://abob.libs.uga.edu/bobk/nuclear.html http://www.godlikeproductions.com/forum1/message1177057/pg1 ^^ [/quote]
Living snails that carbon-date to 2,300 years old, a living seal that was carbon-dated at 1,300 years old, and 8,000-year-old living penguins.
Tell me this scientists... how do you know the half-life of carbon has remained a constant variable throughout time?
