Nope, if there were changes in radioactive decay rates they would not compound. As proven by the simple first-year algebra that I posted and you were unable to understand.
And contamination is not a problem in the vast majority of methods in use over the last few decades, because if it exists it is detected as part of the method.
Before you criticize, you need to learn what you are criticizing. |
I have already cited you proof that contamination is a major problem.
you and reciprocal Bill under the impression that this small percentage change is a single event but I cited findings of multiple changes in decay rates occurring even within one week's time. Now imagine all the alterations that would occur from major perturbations over so called millions of years and you have an even more ridiculous psuedoscience than it already is. |
I've got a little free time waiting for something to finish .... let's take a look at all the messages from ol' forastero which contain the word "contamination".
Quote (forastero @ Oct. 23 2011,04:40) | Again more so called pseudoempericism and to say that no kinds of radiometric contamination are alterations occurred in billions or even thousands of years is as ridiculous as saying dinosaur soft tissue can last millions of years. |
Quote (forastero @ Nov. 05 2011,04:10) | Its pseudoempericism to say that no kinds of radiometric contamination are alterations occurred in billions or even thousands of years is as ridiculous as saying dinosaur soft tissue can last millions of years. Plus, please tell me how this type of radiometric dating{sic} |
Quote (forastero @ Nov. 05 2011,05:20) | You didnt read my position carefully, dinosaurs and mammals may have often lived in much different niches but when they are found in the same vicinity its their strata are automatically separated or referred to as contamination |
Quote (forastero @ Nov. 06 2011,03:45) | Oh and contamination is also still a problem |
Quote (forastero @ Nov. 07 2011,20:37) | Contamination is a big problem but I'll also pick on your best Cyclostratigraphy |
Quote (forastero @ Nov. 08 2011,11:58) | Then on top of this, you have all the contamination and calibration problems of radiometric dating |
Quote (forastero @ Nov. 10 2011,00:14) | Btw, according to "geologists" nuclear decay is most always defined as random as is often the case with fluctuations in solar flares, the magnetic field, cosmic rays, isotope contamination by flash floods, quantum tunneling, radioisotopic substitutions, etc.. etc.. etc... |
Quote (forastero @ Nov. 10 2011,01:55) | Isochron is a dating method based on radioisotpic decay and why have you continually avoided answering how on earth it is calibrated and avoids contamination? |
Quote (forastero @ Nov. 10 2011,13:02) | Oh so thats why you you feel the need to focus "only" on this problem while ignoring the contamination and calibration problems that I keep asking you about |
Quote (forastero @ Nov. 10 2011,13:38) | Btw 2, you also seem to be projecting your own inabilities to put arguments in your own words? Isochron dating is taking several measurements from several surrounding samples with several radioisotopes. It doesnt mean though those surrounding rocks were not all drenched and for millennia by the same radioisotopic contamination. It also doesnt dismiss the fact that scientists have such a bias that they throw out any estimates that dont fit their preconceived agendas. Agendas further verified by all the the recent brouhaha about fluctuating decay fluctuations. |
Quote (forastero @ Nov. 11 2011,21:15) | Finally, not only does your Isochron dating (like with your Argon) dating suffer contamination from various sources before and during crystallization, but igneous rocks have unknown magma ratios of radioisotopes that can produce wide discrepancies in post crystallization ratios. Sedimentary rocks, which contain most fossils are even more prone to unknown mixing, contamination, and ratios. |
Quote (forastero @ Nov. 11 2011,23:33) | Actually, I believe its probably often much more than .05% and the perhaps weekly decay fluctuations accumulate to totally alter any reasonable measurement beyond 5000 years Its proven though that Radiometric dating has much greater problems than fluctuating decay rates. For instance the dinosaur soft tissues. The calibrating errors and circular reasoning involved in calibration. Fluctuating production of radioisotopes. Contamination from various sources. Igneous rocks having unknown magma ratios of radioisotopes that can produce wide discrepancies in post crystallization ratios. Sedimentary rocks, which contain most fossils are even more prone to unknown mixing, contamination, and ratios. |
Quote (forastero @ Nov. 12 2011,21:19) | Again, the fluctuations, assumptions, circular calibrations, contaminations, religious fervor, etc etc etc make your radiomagic dating a joke |
Quote (forastero @ Nov. 15 2011,12:07) | So called millions of years of sedimentary and magma mixing, flooding, erosion, and uplift, yet no contamination in the rocks? Nah, just more more radiomagic formula waving from crony academicism. |
Quote (forastero @ Nov. 15 2011,15:56) | Plus you are still ignoring the following:
Mineral isochrons and isotopic fingerprinting: Pitfalls and promises Geology; January 2005; v. 33; no. 1; p. 29-32 Abstract: "The determination of accurate and precise isochron ages for igneous rocks requires that the initial isotope ratios of the analyzed minerals are identical at the time of eruption or emplacement. Studies of young volcanic rocks at the mineral scale have shown this assumption to be invalid in many instances. Variations in initial isotope ratios can result in erroneous or imprecise ages. Nevertheless, it is possible for initial isotope ratio variation to be obscured in a statistically acceptable isochron. Independent age determinations and critical appraisal of petrography are needed to evaluate isotope data. If initial isotope ratio variability can be demonstrated, however, it can be used to constrain petrogenetic pathways."
Now consider the fact that sedimentary layers, which contain 99% of all fossils, are even more mixed and contaminated than the igneous contamination described above |
Quote (forastero @ Nov. 16 2011,12:21) | All you are doing is "saying" the sedimentary rocks are uncontaminated and dated accurately, which doesnt make it so. Do you at least agree that sedimentary rocks would have a lot more mixing and isotope contamination than igneous rocks? |
Quote (forastero @ Dec. 02 2011,13:34) | Yeah about five times now but here it goes again: A little contamination here and a little change in decay rates there day after day over many millennia leads to exponential inaccuracies and radiomagic dating. Thats what happens when you make science your religion |
Quote (forastero @ Dec. 02 2011,22:11) | All kinds of nuclear interactions, transmutations,, substitutions, contamination, oscillations in energy states and rates , occur via various catalyses due to changes in temperature, radioactive emissions, electricity, cosmic ray spallation , Photodisintegration, radioisotopic mixing and substitutions, chemicals etc... Its the quantum tunneling we were talking about last week. Its like what Ogre’s own link was referring to when the author talked about Big Bang deuterium Fusion and Nuclearsynthesis |
So, sonny boy, which one of those messages is your "cited ... proof that contamination is a major problem"? I don't see a single piece of data or cite of any study in the whole shebang.
Wotta maroon!!
