Creationism vs radiometric dating
In most instances, these efforts are flawed because the authors have misunderstood or misrepresented the data they attempt to analyze (for example, Woodmorappe 1979; Morris HM 1985; Morris JD 1994).
Only rarely does a creationist actually find an incorrect radiometric result (Austin 1996; Rugg and Austin 1998) that has not already been revealed and discussed in the scientific literature.
where is the half-life of the element, is the time expired since the sample contained the initial number atoms of the nuclide, and is the remaining amount of the nuclide.
Radiometric dating of rocks and minerals using naturally occurring, long-lived radioactive isotopes is troublesome for young-earth creationists because the techniques have provided overwhelming evidence of the antiquity of the earth and life.
Pygmy elephants on Flores, now extinct, showed the same may have been small when they first reached Flores. Matt Tocheri, does research on this enigmatic early human species; read more about this work, and watch a video about it on this page.
A joint Indonesian-Australian research team found LB-1—a nearly complete female skeleton of a tiny human that lived about 80,000 years ago—in Liang Bua cave on the island of Flores, Indonesia.
Their result of 212–230 million years did not agree with the age of the fossils (elephant, pig, ape and tools) so they rejected the date.
Before 1955, ages for the Earth based on uranium/thorium/lead ratios were generally about a billion years younger than the currently popular 4.5 billion years. old Earth is reviewed and deficiencies of the uranium/lead method are discussed.Paleoanthropologists found many stone tools associated with , and these tools are broadly similar to those found earlier on Flores and throughout the human evolutionary career (i.e., Lower Paleolithic tools in Asia or Oldowan tools in Africa).Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy.The time that it takes for half of a sample to decay is known as the half life of the isotope.Some isotopes have half lives longer than the present age of the universe, but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.
