Archived from the original on June 29, See also: Jack C. Radiometric Dating In radiometric dating, the measured ratio of certain radioactive elements is used as a proxy for age. Kelvin calculated the age of the Earth by using thermal gradientsand he arrived at an estimate of about million years. Related Media.
Five billion years is five million times greater than one thousand years.
AGE OF THE EARTH
But we now have compelling evidence that this assumption is false. Archived PDF from the original on 16 December This may be the main reason why radiometric dating often gives vastly inflated age estimates. I'm looking for an explanation against Meert's argument that if the decay rates reflected years, currently the earth would be a molten blob due to the massive energy used for the decay. In fact, it is very wrong. Chemical Abstracts.
