Carbon-dating is useful for archaeology, where it can date evidence of human artefacts up to fifty thousand years old.Some less less informed "Young Earth" creationists do believe that carbon-dating was used to date the earth. The length of time required for one-half of the unstable carbon — 14 nuclei to decay i.Libby began testing his carbon — 14 dating procedure by dating objects whose ages were already known, such as samples from Egyptian tombs.Carbon dating is a method of telling approximately how old an ancient object is. The scientists used carbon dating and decided that the mummy was 10,000 years old. Carbon dating is the radio-activity of Carbon 14 which is unstable so it emits protons once in a while in order to become a more stable isotope.

The difference between the concentration of carbon — 14 in the material to be dated and the concentration in the atmosphere provides a basis for estimating the age of a specimen, given that the rate of decay of carbon — 14 is well known.Starting where Boltwood and Libby left off, scientists began to search for other long-lived isotopes.They developed the uranium-thorium method, the potassium-argon method, and the rubidium-strontium method, all of which are based on the transformation of one element into another.You may now see our list and photos of women who are in your area and meet your preferences.Again, please keep their identity a secret Click on the "Continue" button search with your zip/postal code.
