Radiometric Dating

Dating methods must also rely on another kind of science called historical science. Historical science cannot be observed. Determining the conditions present when a rock first formed can only be studied through historical science. Determining how the environment might have affected a rock also falls under historical science. Neither condition is directly observable. We can use scientific techniques in the present, combined with assumptions about historical events, to estimate the age. Therefore, there are several assumptions that must be made in radioisotope dating. Three critical assumptions can affect the results during radioisotope dating: The initial conditions of the rock sample are accurately known.

How Do Scientists Measure Earth Age

Carbon , Radiometric Dating and Index Fossils Carbon dating is used to determine the age of biological artifacts up to 50, years old. This technique is widely used on recent artifacts, but educators and students alike should note that this technique will not work on older fossils like those of the dinosaurs alleged to be millions of years old.

This technique is not restricted to bones; it can also be used on cloth, wood and plant fibers.

evidences for a young age of the Earth and the universe. evidences for a young age of the earth and the universe is an extensive list of arguments for young Earth creationism Incongruent radioisotope dates using the same technique argue against trusting the dating methods that give millions of years.

We have been told that dating methods, such as the rates of decay of radioactive elements, force an honest observer to an old-Earth conclusion. One of the most glaring problems with such reasoning is that it is based on assumptions that have proven to be incorrect. For years, that assumption has been shown to have serious problems DeYoung , and recent findings have made that assumption even more glaringly false.

The implications of such a discovery are profound. Stanford professor emeritus of applied physics Peter Sturrock stated: Further research, however, suggested that the information was not an experimental mistake. In December of , Jere Jenkins, a nuclear engineer at Purdue University, noticed that the decay rate of manganese dropped slightly just before and during a solar flare. Jenkins and Fischbach argue that this variation in decay rates is caused by interaction between solar neutrinos and the radioactive elements being observed.

This latest research brings to light the glaring flaw of such dating methods, showing that the core assumptions are not only questionable, they are verifiably false. The suggestion that decay rates may be affected by neutrinos is nothing new. The responses given by TalkOrigins do not include the new data from the latest research, and cannot dismiss the fact that the rates of radioactive elements are measurably variable, even though the neutrino interaction with them is little understood Since we can prove that certain radioactive elements have a rate that varies in the winter or summer, or during solar flares, then the assumption that decay rates are constant cannot honestly be maintained.

Yet this assumption has been proven false, based on the fact that decay rates have been shown to vary.

The age of the Earth was a matter of speculation till very recent times and as such there was divergence of opinions about the antiquity of the Earth. Until recently geology relied extensively on the concept of the relative age of rocks. The determination of the age of the earth was attempted through two distinct processes? Indirect methods for ascertaining the earth’s age, and 2.

Radioactive methods for determining the actual age Direct- method. Indirect Methods a Sedimentation-Clock This takes into account the average annual rate of sedimentation and the thickness of all strata deposited during the whole geological history.

Radioisotopes and the Age of the Earth: Results of a Young-Earth Creationist Research Initiative (Chapter 8) A remarkable finding since the early ’s is that organic samples from every level in the Phanerozoic portion of the geological record, when tested by highly sensitive accelerator mass spectrometer (AMS) methods, display.

While there are numerous natural processes that can serve as clocks, there are also many natural processes that can reset or scramble these time-dependent processes and introduce uncertainties. To try to set a reasonable bound on the age, we could presume that the Earth formed at the same time as the rest of the solar system. If the small masses that become meteorites are part of that system, then a measurement of the solidification time of those meteorites gives an estimate of the age of the Earth.

The following illustration points to a scenario for developing such an age estimate. Some of the progress in finding very old samples of rock on the Earth are summarized in the following comments. It is a compound of zirconium, silicon and oxygen which in its colorless form is used to make brilliant gems. Samples more than 3. Older ages in the neighborhood of 4. The graph below follows the treatment of Krane of Rb-Sr studies of meteorite samples from Wetherill in order to show the nature of the calculation of age from isochrons.

Relative dating Studies of strata , the layering of rocks and earth, gave naturalists an appreciation that Earth may have been through many changes during its existence. These layers often contained fossilized remains of unknown creatures, leading some to interpret a progression of organisms from layer to layer. Lomonosov’s ideas were mostly speculative. In the Comte du Buffon tried to obtain a value for the age of Earth using an experiment: He created a small globe that resembled Earth in composition and then measured its rate of cooling.

This led him to estimate that Earth was about 75, years old.

By Wayne Jackson Dr. Others allege that the Bible simply does not speak to this matter. Ross, see Van Bebber and Taylor The Basic Issue If it is true that the Bible is completely silent on this topic, then certainly we ought not to make an issue of it. But, is the Bible silent regarding the age of the earth and the human race? We pose these questions for reflection:

Geochronology

February 27, By dating the rocks in the ever-changing crust, as well as neighbors such as the moon and visiting meteorites, scientists have calculated that Earth is 4. How old are your rocks? Several attempts to scientifically date the planet have occurred over the past years.

The primary method for dating age of teh Earth is radiometric dating specifically elements like Uranium and elements have a very long decay rate and decay into known elements. We thus look at the amounts of these elements in rocks and can determine how old the rock is.

The only dating methods discussed over and over by evolution-believing scientists and the mass media are those that supposedly “prove” that the earth is billions of years old. One of the most popular of these is known as radiometric dating. However, not as well known is the fact that such methods have serious flaws which are often glossed over, or ignored when writing on, or discussing this subject in public. Another pertinent thing that’s also ignored, minimized, or scoffed at are the numerous other scientific methods of dating the earth, solar system, and or universe that yield much younger ages than million years max.

With the exception of Carbon , radiometric dating is used to date either igneous or metamorphic rocks that contain radioactive elements such as uranium. And even though various radioactive elements have been used to “date” these rocks, for the most part, the methods are basically the same. They consist of measuring the amount of radioactive mother element and comparing it to the amount of stable daughter element. Uranium is radioactive, which means it is in the process of changing from an unstable element into a stable one.

The most common form is uranium It has a half-life of about 4. This means that if you had some pure uranium with no lead in it, 4. Few people realize it but all radiometric dating methods require making at least three assumptions. For years it was assumed that decay rates from mother to daughter element was constant.

New Findings Show Flaws In Old-Earth Dating Methods. by Kyle Butt, For decades the general population has been informed that numerous “scientific” evidences prove beyond all doubt that the age of the Earth should be measured in billions of years instead of thousands.

V where X is the model’s forcing function i. In the latest marine benthic oxygen isotope stack, LR04, of Lisiecki and Raymo [54], the same model has been applied Fig. The latest estimates include ice sheet fluctuations at Antarctica, Greenland, Eurasia and North America. A plot of the total ice volume component, expressed in terms of sea level equivalent, is shown in Fig. The calculated eustatic sea level changes share similar orbital-induced features as independent sea level reconstructions from the Red Sea [58,59], although the modelled values are at the upper confidence limits of the reconstructions Fig.

In addition, they clearly lack short-term millennial-scale changes, due to smoothing and the on-average lower resolution. During deglaciations, surface air temperature and sea level increase almost in concurrence, presumably the result of the rapid meltdown of the large ice sheets, with modelled reconstructed sea level rises of over 1. First, there is some uncertainty in the parameterization of the deepwater-atmosphere temperature coupling in the model.

Although the chronology of the last glacial cycles is well constrained, conflicting estimates were found for the age of the penultimate and earlier deglaciations, which argued in favour [65] or against [66—68] an NH summer insolation forcing mechanism. Dating uncertainties in this timescale range from 0. Given these uncertainties, the increases in Antarctic temperature and atmospheric carbon dioxide concentration coincide with the rising phase of NH summer insolation during the last four terminations Fig.
