Willard Libby, pHd. Sunlight strikes the atmosphere, changing nitrogen into c, and the c slowly decays back into nitrogen. Libby said at some point, the formation rate and decay rate will equalize. On a newly formed earth, this would take about 30, years. Tests show that c is still increasing in the atmosphere, which proves the earth is less than 30, years.
Does carbon dating prove the earth is millions of years old?

Figuring out how old something is can be hard. For short times, the number of winters that have come and gone since the event can simply be counted. But this gets trickier over longer times. Over the timescale of human history, maybe someone turns to their library to study the histories that have been written. From that, they can piece together how long ago something happened. But things are not always that easy. What if something happened before writing was invented?

Seventy years ago, American chemist Willard Libby devised an ingenious method for dating organic materials. His technique, known as carbon dating, revolutionized the field of archaeology. Now researchers could accurately calculate the age of any object made of organic materials by observing how much of a certain form of carbon remained, and then calculating backwards to determine when the plant or animal that the material came from had died.
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.
