We need to look at the data and see whose interpretive framework fits the data the best. At the current rate of decline it could take just 1,500 years to disappear, with increasing effects upon the electronic systems of satellites and spacecraft. However, geologists have found that various eruptive stages of the same volcano often extrude lavas exhibiting somewhat different mineral compositions, particularly if an extensive period of time separated the eruptions. So if the speed of light slows down, then the radioactive decay rate also slows down,. Another problem with isochrons is that they can occur by mixing and other processes that result in isochrons yielding meaningless ages.
One can get this mixing to work with smaller concentrations, too. This would tend to produce compounds with a high dipole moment, with a positive charge on uranium and a negative charge on the other elements. There are three reasons why radiometric data is known to be accurate: 1. Even if multiple tree ring growth is rare today how can we know it was the same in the past? Rather, this entry wishes to point out that radiometric dating, while certainly not infallible, has less of a margin for error, and thus has a higher chance of being correct. If Snell's critiques were valid general criticisms he would publish them in the peer-reviewed literature rather than unreviewed religious tracts. After a long enough time the minority isotope is in an amount too small to be measured.
Oftentimes the rate of cooling occurs rapidly enough to prohibit the complete transformation of calcium-rich feldspar into sodium-rich feldspar. That is, after two half-lives, 100% of the C-14 atoms will not have decayed into N-14 atoms. Creationists really don't have a theory that can be proved, so they cannot succeed by that approach. It is now time to compare the pros and cons. Although these minerals crystallize in the order shown, this sequence is not a true reaction series. It appears that at one or more stages in the crystallization process, a separation of the solid and liquid components of a magma frequently occurs.
Suppose also that N2 and N3 differ significantly. It has nothing to do with his data being weak, but has everything to do with the current bias in the scientific community. Con then claims that all scientists always do the same. The theories made predictions confirmed by observation. Then we require some process to preferentially concentrate the parent substances in certain places. All Con has done is cite a few limitations on some of the specific methods.
Only a limited God would be required to use magic. It's been an eye opener to me to see all the processes that lead to segregation of different minerals in the magma. For example, it has been known since the 1960s that the famous Cretaceous-Tertiary boundary, the line marking the end of the dinosaurs, was 65 million years old. Non-scientists are free to assign any of the thousands of supernatural explanations they wish. Each dating method has it;s pros and cons, they should be.
Finally, if one only considers U-Pb and Th-Pb dates for which this test is done, and for which mixing cannot be detected. Objections fully answered 50 years ago are recited like scripture. Its hard to publish anything when the publishers laugh at you when you even suggest it. There was no general problem with radiocarbon dating. These long time periods are computed by measuring the ratio of daughter to parent substance in a rock and inferring an age based on this ratio. So this implies some kind of chemical fractionation. If this occurs, initial volcanic eruptions would have a preponderance of daughter products relative to the parent isotopes.
Overtime, the C-14 atoms give off radiation, and, eventually, transform into nitrogen-14 atoms. Both are not entirely inaccurate, but neither are both entirely accurate. This, of course, is so that it can be properly catalogued, and, if valid, can be related to or associated with other objects from the same era. If decay had been accelerated in the past so would have fission tracks and electron spin resonance. Absolute dating has proved disappointing. The overall theme is that of a very old earth.
Two of those are a-decaying isoptopes and b-decaying isotopes. Clearly, this seems incompatible with an ocean billions of years old. Such a massive inaccuracy is inexcusable. Surely every believer must grant that God could accomplish His will by working solely through repeatable laws of nature. Potassium-Argon and Argon-Argon Methods Both these methods suffer from the same problems, because they are both based on the radioactive decay of potassium K to argon Ar , a gas which does not bond with other elements. However, more recent work has indicated that this process cannot account for the relative quantities of the various rock types known to exist. I now show that the mixing of three sources can produce an isochron that could not be detected by the mixing test.
Con All radioactive dating except Carbon 14 are based on atoms found in igneous rocks. Believing in magic is contrary to being a scientist. The technique gave 90 million years, but took no account of the non-constant erosion rate, or the loss and recycling of salt, or the fact that salt is obtained from other sources as well as continents. Uranium in the major uranium deposits in the San Juan basin of New Mexico is believed to have been derived from silicic volcanic ash from Jurassic island arcs at the edge of the continent. How anyone can keep track of this all is a mystery to me, especially with the difficulties encountered in exploring magma chambers. Usually the concentration of uranium and thorium varies in different places in rock. Suppose P p is the concentration of parent at a point p in a rock.
