Most people think that radioactive dating has proven the earth is billions of years old.After all, textbooks, media, and museums glibly present ages of millions of years as fact.Before then, the Bible had provided the only estimate for the age of the world: about 6,000 years, with Genesis as the history book.Hutton's theories were short on evidence at first, but by 1830 most scientists concurred that Noah's ark was more allegory than reality as they documented geological layering.I found several good sources, but none that seemed both complete enough to stand alone and simple enough for a What is radiometric dating?Simply stated, radiometric dating is a way of determining the age of a sample of material using the decay rates of radio-active nuclides to provide a 'clock.' It relies on three basic rules, plus a couple of critical assumptions.

Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.6 billion years.Segment from A Science Odyssey: "Origins."Geologists have calculated the age of Earth at 4.6 billion years.The rules are the same in all cases; the assumptions are different for each method.To explain those rules, I'll need to talk about some basic atomic physics. Hydrogen-1's nucleus consists of only a single proton.
