How are fossils dated using radiometric dating dating jennifer anniston
If this trend were to continue, the earth would be 700 thousand-trillion-trillion-trillion years old by the year 4000 AD.
This “prediction,” however, is based on selected data and certain assumptions that might not be true.
No wonder the laboratories that “date” rocks insist on knowing in advance the “evolutionary age” of the strata from which the samples were taken—this way, they know which dates to accept as “reasonable” and which to ignore.
Of one thing you may be sure: whenever “absolute” radiometric dates are in substantial disagreement with evolutionary assumptions about the age of associated fossils, the fossils always prevail.
And fourth, one must be certain that the decay rate of parent isotope to daughter isotope has always been the same.
That one or more of these assumptions are often invalid is obvious from the published radiometric “dates” (to say nothing of unpublished dates) found in the literature.
Lava flows from volcanoes on the north rim of the Grand Canyon (which erupted after its formation) show potassium-argon dates a billion years “older” than the most ancient basement rocks at the bottom of the canyon.
Apollo moon samples, for example, were dated by both uranium-thorium-lead and potassium-argon methods, giving results that varied from 2 million to 28 billion years. Much of the controversy between evolutionists and creationists concerns the age of the earth and its fossils.At the time Darwin’s On the Origin of Species was published, the earth was “scientifically” determined to be 100 million years old. In 1947, geologists firmly established that the earth was 3.4 billion years old.These radiometric “clocks” begin keeping time when the molten rock solidifies.
Since fossils are rarely found in igneous rocks, one can only date lava flows that are occasionally found between layers of sedimentary rock.The so-called “absolute” methods of dating (radiometric methods) actually only measure the present ratios of radioactive isotopes and their decay products in suitable specimens—not their age.
