Carbon dating age of earth
Before we get into the details of how radiometric dating methods are used, we need to review some preliminary concepts from chemistry.Recall that atoms are the basic building blocks of matter.He argues the few instances in which radiometric dating has produced anomalous results “may be due to laboratory errors (mistakes happen), unrecognised geologic factors (nature sometimes fools us), or misapplication of the techniques (no-one’s perfect)”.Dalrymple also notes scientists do not rely solely on the self-checking nature of radiometric dating to confirm their results.(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.a great majority of the time” that Earth is billions of years old.
Dating schemes based on rates of radioactivity have been refined and scrutinised over several decades, and the latest high-tech equipment permits reliable results to be obtained even with microscopic rock samples.A 2010 Gallup poll found 40% of Americans believe that “God created humans in their present form within the last 10,000 years”.A 2009 poll found 39% agreed that “God created the universe, the earth, the sun, moon, stars, plants, animals and the first two people within the past 10,000 years”.
