Based upon radiometric dating the age of the earth is
Radiometric dating is self-checking, because the data (after certain preliminary calculations are made) are fitted to a straight line (called an isochron) by means of standard linear regression methods of statistics.The slope of the line determines the age of the rock, and the closeness of fit is a measure of the statistical reliability of this conclusion.But recently the prices of these devices have dropped to levels that even amateur meteorite hunters and others can afford.Used mass spectrometers are currently available at e Bay for as little as US.
Dalrymple also notes scientists do not rely solely on the self-checking nature of radiometric dating to confirm their results.Plate tectonics then threw the crushed rock back into the interior of the Earth, removing the old evidence and turning it into new rock.In the early 20th century, scientists refined the process of radiometric dating.(By contrast, and more representative of OECD countries, only about half as many Canadians espouse such beliefs.) Such notions, of course, differ vastly to the findings of modern science, which pegs the age of the earth at 4.56 billion years, and the age of the universe at 13.75 billion years.While there are numerous experimental methods used to determine geologic ages, the most frequently employed technique is radiometric dating, based on measurements of various radioactive isotopes in rocks.
