We make our world significant by the courage of our questions and by the depth of our answers. Earth Sciences How far back can you go before carbon dating becomes unreliable? How far back can you go before carbon dating becomes unreliable? Yesterday I was speaking with a friend who is a Jehovah's Witness, so obviously he believes in the flood, and that humans have only been on the earth for 6, He says he knows a lot about carbon dating, and that it's only accurate if you're dating something that's within the last 3, years, after that, it can be very inaccurate. He also says that water will cause extreme variation in dating, do for example an object only years old that's been in water for that time may be dated at 1, years old.
Does carbon dating prove the earth is millions of years old?

We make our world significant by the courage of our questions and by the depth of our answers. Archaeology [Archaeology] How far back can radiocarbon dating really reach? And how do we know this? However, Wikipedia notes that this carbon curve has only validated radiocarbon dating back 8, years. For example, samarium-neodymium dating can go back billions of years and get precision to within less than twenty million years.
Radiocarbon Tree-Ring Calibration
How far can you go back in time, and assume an accurate sample with carbon dating? It seems limited, how can an observer know the state of the decay of a certain molecular structure even , calendar years ago? Could there be other influences that would affect the rate of decay of carbon 14? If it has generally been established as a constant, at what point does the "constant" break down? The constant, that is the Strong Nuclear Force, is absolute.
Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s at the University of Chicago by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.
