Flaws in radiometric dating Dating girls for sex without upgrading
anthropologist Geoffrey Clark echoed this view in 1997 when he wrote that 'we select among alternative sets of research conclusions in accordance with our biases and preconceptions -- a process that is, at once, both political and subjective.'In the case of fossils; which are essentially bones that have fossilized, meaning turned to stone; fossils are generally dated on the basis of factors other than radiometric dating; such as a particular date may be chosen for a fossil because Thus, if "Fossil A" is believed to be 4,000,000 years old, "Fossil B" may be dated to be 3,700,000 years old solely on the basis of the date of "Fossil A" and a belief in evolution (i.e.it is dated based on where "Fossil B" fits on the phylogenetic tree relative to "Fossil A"). when an unstable parent atom becomes a stable daughter atom, the dating of the specimen can no longer be done accurately), dating of old fossils is generally impossible to do directly.Then, by assessing the isotope concentrations of rubidium and strontium, scientists can back-calculate to determine when the rock was formed.The three isotopes mentioned can be used for dating rock formations and meteorites; the method typically works best on igneous rocks. The data from radioisotope analysis tends to be somewhat scattered.The number of protons in an atom determines which element it is, while the number of neutrons determines which isotope it is.For example, strontium-86 has 38 protons and 48 neutrons, whereas strontium-87 has 38 protons and 49 neutrons.Note that Carbon Dating uses a different method that I will discuss momentarily .The radioactive material is alway decaying into something, but if the material is in a molten state, the decay products will not stay in place.
Dividing the isotope concentrations of all the forms of strontium and rubidium by the isotope concentration of strontium-86 generates something called the "isochron." The isochron is then plugged into a model, which uses it to turn the overall radioisotope data into a clear, linear function.
For example, a team at Purdue University in Indiana was monitoring a lump of manganese-54 in a radiation detector box to measure the isotope’s half-life.
At PM on December 12, 2006, the instruments recorded a sudden dip in radioactivity.
Furthermore, even if many animals had become extinct in Australia (for example), there is no reason to think that God could not have put them back in Australia after the flood, assuming they were there before the flood.
Scientists may not know when the climate changed and an area of earth which was highly exposed to water (e.g.
