Counterexamples to an Old Earth (view source)
Revision as of 21:11, June 26, 2010
, 21:11, June 26, 2010→Geology: radioactive decay in the interior, can't think of more off the top of my head
# All [[carbon dating]] of water supplies, even the most ancient and the deepest underground reservoirs, result in relatively young ages,<ref>http://www.betalabservices.com/PDF/Geyh.pdf</ref> and no water has been found suggesting an Old Earth.

# The ratio of strontium isotopes in seawater, which should change due to long-term erosion, has varied by only 0.35% throughout history. In fact, its value today is exactly the same as in the oldest samples, which are claimed to be from 500 million years ago!

# The interior of the earth is heated by decay of radioactive isotopes, which could not possibly still be persisting in sufficient quantities after 5 billion, or even half a billion, years.
