Radiocarbon dating is a key tool archaeologists use to determine the age of plants and objects made with organic material. But new research shows that commonly accepted radiocarbon dating standards can miss the mark -- calling into question historical timelines. Archaeologist Sturt Manning and colleagues have revealed variations in the radiocarbon cycle at certain periods of time, affecting frequently cited standards used in archaeological and historical research relevant to the southern Levant region, which includes Israel, southern Jordan and Egypt. These variations, or offsets, of up to 20 years in the calibration of precise radiocarbon dating could be related to climatic conditions.
ERRORS ARE FEARED IN CARBON DATING
A Crucial Archaeological Dating Tool Is Wrong, And It Could Change History as We Know It
This is what my born again Christian friend tries to explain to me everytime we talk about evolution. In the past I've held my ground quite firmly on this topic, but as of recently he has made some claims from some "scientific journals" that carbon dating may not be as accurate as thought, and that it is misleading. I have a hard time believing anything he really says about this, but my question comes down to this, how accurate is carbon dating and how sure are we it works? When I was at primary school I learned that you could tell the age of a tree by counting the rings.
How Accurate is Carbon Dating?
Whenever the worldview of evolution is questioned, the topic of carbon dating always comes up. Here is how carbon dating works and the assumptions it is based upon. Radiation from the sun strikes the atmosphere of the earth all day long. This energy converts about 21 pounds of nitrogen into radioactive carbon This radioactive carbon 14 slowly decays back into normal, stable nitrogen.
Until now, I have assiduously avoided Ancient Aliens. I had a feeling that if I watched the show—which popularizes far-fetched, evidence-free idiocy about how human history has been molded by extra-terrestrial visitors—my brain would jostle its way out of my skull and stalk the earth in search of a kinder host. Or, at the very least, watching the show would kill about as many brain cells as a weekend bender in Las Vegas. I steeled myself for the pain and watched the mind-melting madness unfold. If they did, my entire review would be little more than a string of expletives.
