Radio carbon dating stone tools

When a creature dies, it ceases to consume more radiocarbon while the C-14 already in its body continues to decay back into nitrogen.So, if we find the remains of a dead creature whose C-12 to C-14 ratio is half of what it's supposed to be (that is, one C-14 atom for every two trillion C-12 atoms instead of one in every trillion) we can assume the creature has been dead for about 5,730 years (since half of the radiocarbon is missing, it takes about 5,730 years for half of it to decay back into nitrogen).These standard calibration curves assume that at any given time radiocarbon levels are similar and stable everywhere across each hemisphere. "We went looking to test the assumption behind the whole field of radiocarbon dating," Manning said.

However, there is strong evidence which suggests that radioactive decay may have been greatly accelerated in the unobservable past.It look that the ' Gods' messed up with our website ....For some reason this page that you have tried to access doesn't exist for one or more of the following reasons:a) The ' Gods' didn't like itb) Secret services or Governments didn't like itc) Archaeologists or scientists didn't like itord) this page doesn't exist anymoree) There is a temporary error and in that case PLEASE try again!

This is an informational tour in which students gain a basic understanding of geologic time, the evidence for events in Earth’s history, relative and absolute dating techniques, and the significance of the Geologic Time Scale.
