[QUOTE="muff07"][QUOTE="Big_Bad_Sad"]What is so outrageous about that? Carbon dating has given them the idea of it being that old. Its not a definite figure but its probably in the area.Locke562
Actually C-14 (Or Caron dating as it's commonly reffered to) is only acurate to 14,000 years due to the relativly short half-life of the Caron atom. The oldest rocks in the world have been dated to2.45 Billion years old using Uranium and other Unstable isotopes half-lifes to atain date. After2.45 billion years it goes down to theories on how long certain sequences of events are thought to have take eg. Cooling of Earth from molten fire ball to a cool solid outter crust.
But the Big Bang is based on all are current knowledge on the cosmos and universe and predictions/simulations from computers. It's much like how people thought the world was flat, a new idea could emerge from new information.
But the biggest thing that (Almost) proves the Big Bang theory is that The further away a selestial object is the further the shift to the red side of the spectrum it is, I.e the further away something is the faster it is moving away (Also meaning the universe is expanding) and this must have occured from a single point.
I thought carbon dating using Carbon-14 was accurate up to roughly 50,000 years.correct, it is accurate to around 50000-65000. after that the peices become to small to work with. there are many though that have much long half-lives( and ones with much shorter)
