When asked for your age, it's likely you won't slip with the exception of a recent birthday mistake. But for the sprawling sphere we call home, age is a much trickier matter. Before so-called radiometric dating, Earth's age was anybody's guess. Our planet was pegged at a youthful few thousand years old by Bible readers by counting all the "begats" since Adam as late as the end of the 19th century, with physicist Lord Kelvin providing another nascent estimate of million years. Kelvin defended this calculation throughout his life, even disputing Darwin's explanations of evolution as impossible in that time period.
From cave art to climate chaos: how a new carbon dating timeline is changing our view of history
The authors would like to thank Dr. Dating Diamonds. Shirey explains the study of radiogenic isotopes hidden inside individual diamond inclusions to determine their age and hence the age of the diamonds themselves. View Gallery. This slideshow takes you through the processes Dr.
Image from Wikipedia. What kind of evidence do we have to support the notion that the Earth is truly ancient? However, there are some aspects of evidence for an old earth that seem to defy this argument, particularly because they interlink in such a way that independently points towards an old earth. Here, I take a look at an article by Gregg Davidson and Ken Wolgemuth in which they make this very argument.
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
