Using the known rate of change in radio-active elements (radiometric dating), some Earth rocks have been shown to be billions of years old, while the oldest solar system rocks are dated at 4. 6 billion years. . Their results consistently agree with an old Earth. Over a thousand papers on radiometric dating were published in scientifically recognized journals in the last year, and hundreds of thousands of dates have been published in the last 50 years. Essentially all of these strongly favor an old Earth.

Nonetheless, stratigraphy and radiometric dating of Precambrian rocks have clearly demonstrated that the history of the Earth extends billions of years into the past. Radiometric dating has not been applied to just a few selected rocks from the geologic record. . The principal evidence for the antiquity of Earth and its cosmic surroundings is: The oldest rocks on Earth, found in western Greenland, have been dated by four independent radiometric dating methods at 3. 7-3. 8 billion years.
The basic theory of radiometric dating is briefly reviewed. Since 1955 the estimate for the age of the Earth has been based on the assumption that certain meteorite lead isotope ratios are equivalent to the primordial lead isotope ratios on Earth. In 1972 this assumption was shown to be highly questionable. . RADIOMETRIC TIME SCALE has been the development and continuing refinement of the various methods and techniques used to measure the age of Earth materials. Precise dating has been accomplished since 1950. the estimated age of the old wood would be 5,730 years.
How Science Figured Out the Age of Earth. passed between the first use of radiometric dating and the discovery of isotopes, let alone the working out of the three separate major decay chains. Earth sciences - Radiometric dating: In 1905, shortly after the discovery of radioactivity, the American chemist Bertram Boltwood suggested that lead is one of the disintegration products of uranium, in which case the older a uranium-bearing mineral the greater should be its proportional part of lead.
Radiometric Dating: Geologists have calculated the age of Earth at 4. 6 billion years. But for humans whose life span rarely reaches more than 100 years, how can we be so sure of that ancient date?. Many accept radiometric dating methods as proof that the earth is millions of years old, in contrast to the biblical timeline. Mike Riddle exposes the unbiblical assumptions used in these calculations The presupposition of long ages is an icon and foundational to the evolutionary model. Nearly every
/1/2010Scientists admit that radiometric dating, one of the fundamental techniques used to show the earth is billions of years old is flawed!!! The earth is not 4. 55 billion years old. Watch and find out
The age of the earth is 4. 05 billion years 4. 54 10 9 years 1%. This age may represent the age of the earth's accretion, of age of the earth radioactive dating core formation, or of the material from which the earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric
This is why most people say carbon dating is only good for objects less than 40,000 years old. Nothing on earth carbon dates in the millions of years, because the scope of carbon dating only extends a few thousand years. Willard Libby invented the carbon dating technique in the early 1950s.
In the 1920s, Earth's age crept up toward 3 billion years, making it for a time even older than the universe, which was then estimated to be about 1. 8 billion years old.
