Inadvertently, the human page turner, that fallible and sometimes reviled third party onstage, has been absent from most of Haywoodâs recent performances, a consequence of the wireless age. The advantages are obvious: The iPad is portable, discreet, always well-rested.
He measured the half-life of Carbon-14 to be about 5,568 years. However after about 50,000 years there is so little Carbon-14 left in the specimen that it is very hard, almost impossible, to calculate its age. (Van Der Merwe) Libby ran many tests on items where the age was known, or estimated by other means.
Report Abuse. I would think that the moon is about as old as the earth, and would guess that to be about 4.5 billion years. However it is really difficult to document, as none of us where on earth at that time. They use carbon dating to document how much carbon is released from a rock after it is formed. So the 4.5 billion year estimate comes with a disclaimer. It might be off by 4.4 billion years younger, or many trillions of years older than we think it is.
