Evolution's Radiometric Dating Methods: Are they accurate?

radiometric dating is accurate

Or if you prefer, they regularly engage in the error of to excuse clearly erroneous findings. The rate of decay of the parent isotope is known accurately, and has not changed during the existence of the rock or mineral since it crystallized. The thicknesses of the layers and the types of material in them tells a lot about the climate of the time when the layers were deposited. For more, see books by geologists Morris and Austin. Thus not even the highly vaunted consistency of radioactive decay performs as claims.

Debate: Radiometric Dating is Accurate

radiometric dating is accurate

A persuasive book written for the Christian layman. On the other hand, would I bet my life on the supposed age of a rock, or fossil based on radiometric dating and the testimony of some PhD scientists? Some of these techniques allow scientists to chart at what points in time metamorphic heating events have occurred, which is also of significant interest to geologists. This works because if there were no rubidium-87 in the sample, the strontium composition would not change. There are numerous other radiometric dating methods: the samarium-neodymium, lutetium-hafnium, rhenium-osmium, and lead isochron methods just to name a few. It takes just as much faith to believe either one.

The half-life for this radioactive decay is 42 billion years. From that we can determine the original daughter strontium-87 in each mineral, which is just what we need to know to determine the correct age.

Some scientists argue that the magnetic field of the earth has declined over time. Well, look back at the axioms of radiometric dating methods. This same mistake happened again.

It decays to nitrogen 14 with a half life of 5730 years. First, we must assume that the rate of decay of U238 into Pb206 has remained constant over time. One possible source of problems is if a rock contains some minerals that are older than the main part of the rock. However, the rapid decay allows precise dating - accuracy within just a couple decades. The answer has to do with the exponential nature of radioactive decay. Some Christians have argued that something may be slowly changing with time so all the ages look older than they really are. In the extremely hot stellar environment, a completely different kind of decay can occur.

We must remember that the past is not open to the normal processes of experimental science, that is, repeatable experiments in the present. One cannot always assume that there were no daughter atoms to begin with. The sand grains fall from the upper chamber at a constant rate, said to be analogous to radioactive decay. In fact, the amount of helium in the rocks is perfectly consistent with their biblical age of a few thousand years! Now, suppose that one mineral has a lot of Rb87, another has very little, and the third has an in-between amount. However, scientists love to find things that need explanation, and the best thing in science is to find new evidence that overthrows a well-established theory.

It has been demonstrated by atomic clocks in very fast spacecraft. Thus, it logically follows that these assumptions are, strictly speaking, not provable. C14 is continually being created and decaying, leading to an equilibrium state in the atmosphere. Yet, secularists continue to assume that it gives correct age estimates on rocks of unknown age. It may not form the same kinds of compounds.

Method 3: Potassium-Argon Dating The element potassium has three nuclides, K39, K40, and K41. In reality there is always some exchange or influence, but if this amount is completely insignificant for the process under consideration e. They also found some evidence that alpha decay chains were accelerated somewhat more than beta decay chains. Contrary to the impression that we are given, radiometric dating does not prove that the Earth is millions of years old. There are no reliable sources that back up that claim. Estimating Age Since age cannot be measured, how is it estimated? This research is based on yet another element, called helium.

Note that it would be extremely unlikely for another dating method to agree on these bogus ages. Work on radiometric dating first started shortly after the turn of the 20th century, but progress was relatively slow before the late forties. That is not hypocrisy, but being open and up-front about where we are coming from. This radiation causes disorder in the crystals, resulting in electrons dwelling in higher orbits than they originally did. We will also get a distribution of averaged values for samples in each period. The oldest crystals on Earth that were formed on Earth are zircon crystals, and are approximately 4.

Everything Worth Knowing About ... Scientific Dating Methods

In rubidium-strontium dating, micas exclude strontium when they form, but accept much rubidium. We'll never relate to these concepts in the way we relate to everyday existence. In uranium-lead U-Pb dating of zircon, the zircon is found to exclude initial lead almost completely. An effort is presently underway to bridge the gaps so as to have a reliable, continuous record significantly farther back in time. As my opponent pointed out it is assumed the initial quantity of the daughter isotope Ar is not needed because it does not bond easily with other elements and, therefore, when the rock forms all the initial Ar would have escaped. These meteorites are chips off the asteroids.

Here is another way that K-Ar dates can be too old: If we assume the earth went through a catastrophe recently, then the crustal plates might have been agitated, permitting lava and argon to escape from the magma. Such operations normally require about 4 thousand feet of runway for fighter jets. Other methods do not require knowing the initial quantities. If the same assumptions were applied to aviation, particularly military aircraft you could easily see how foolish the person making the statement would appear. If one predicts a carbon-14 age assuming that the ratio of carbon-14 to carbon-12 in the air has stayed constant, there is a slight error because this ratio has changed slightly. Dinosaur bones do not have carbon-14 unless contaminated , as the dinosaurs became extinct over 60 million years ago.
