Potassium argon dating hominids

Overall, the energy of the Earth's magnetic field has been decreasing,[5] so more C is being produced now than in the past.

This will make old things look older than they really are.

So, we have a “clock” which starts ticking the moment something dies.

Obviously, this works only for things which were once living.

These techniques are applied to igneous rocks, and are normally seen as giving the time since solidification.

The isotope concentrations can be measured very accurately, but isotope concentrations are not dates.

When a “date” differs from that expected, researchers readily invent excuses for rejecting the result.

The common application of such posterior reasoning shows that radiometric dating has serious problems.

Anything over about 50,000 years old, should theoretically have no detectable C.Unless this effect (which is additional to the magnetic field issue just discussed) were corrected for, carbon dating of fossils formed in the flood would give ages much older than the true ages.Creationist researchers have suggested that dates of 35,000 - 45,000 years should be re-calibrated to the biblical date of the flood.[6] Such a re-calibration makes sense of anomalous data from carbon dating—for example, very discordant “dates” for different parts of a frozen musk ox carcass from Alaska and an inordinately slow rate of accumulation of ground sloth dung pellets in the older layers of a cave where the layers were carbon dated.[7] Also, volcanoes emit much COC.To derive ages from such measurements, unprovable assumptions have to be made such as: There is plenty of evidence that the radioisotope dating systems are not the infallible techniques many think, and that they are not measuring millions of years. For example, deeper rocks often tend to give older “ages.” Creationists agree that the deeper rocks are generally older, but not by millions of years.Geologist John Woodmorappe, in his devastating critique of radioactive dating,[8] points out that there are other large-scale trends in the rocks that have nothing to do with radioactive decay.

These techniques, unlike carbon dating, mostly use the relative concentrations of parent and daughter products in radioactive decay chains.
