Talk origins radioactive dating How Good Are Those Young-Earth Arguments?

Talk origins radioactive dating, claim cd011:

Claim CF210:

All paleontologists recognized unmistakable trends in morphology through time in the succession of fossil organisms. Any carbon-containing liquid originally possessed by that sponge might well leak over time and be replaced by something else.

However, this statistical likelihood is not assumed, it is testedusually by using other methods e.

Evidence of past history of C concentration in the atmosphere is now available through the past 22, years, using ages of lake sediments in which organic carbon compounds are preserved. Once we have a good approximation of the half-life for carbon, its decay curve can be constructed talk origins radioactive dating complete confidence.

Claim CD031:

In spite of the claims by Cook 2829Morris 92Slusher, DeYoung 37 and Rybkaneither decay rates nor abundance constants are a significant source of error in any of the principal radiometric dating methods. We say that the input and output of water is in equilibrium. The K-Ar ages on rocks and minerals from this area in southwestern Minnesota also record this 1.

Each increment of time in the stratigraphy could be characterized by a particular assemblage of fossil organisms, formally termed a biostratigraphic "zone" by the German paleontologists Friedrich Quenstedt and Albert Oppel.

Hence, we only have to worry about the initial concentration of C in the atmosphere. Thus, we have another remarkable confirmation of the C method. Although geologists can and do legitimately quibble over the exact age of a particular fossil or formation e.

Circular Reasoning or Reliable Tools?

U-Pb concordia-discordia diagram for nine samples of the 3. The numbers above are just summary values. Harold Slusher, a prominent member of the Institute for Creation Research, claimed that "Experiments have shown that the decay rates of cesium and iron 57 vary, hence there may be similar variations in other radioactive decay rates. The C that is incorporated in the carbon structure of cellulose and the other structural materials of living plants and animals is not going to do much migrating after burial.

Free neutrons might change one element into another, but the decay rates all remain true to their elements. Dalrymple does not present the details of his derivation. The chance that neutrinos could have any effect on decay rates or produce nuclear transmutations in sufficient amounts to have any significant effect on our radiometric clocks is exceedingly small.

The overall result is that no one has found any evidence of changes in fundamental constants, to an accuracy of about one part in 10 11 per year.

Geochronologists do not claim that radiometric dating is foolproof no scientific method isbut it does work reliably for most samples. Measurements of the Half-lives of Ra and Pa. Since we are dealing dhaka dating app millions of C atoms in even the smallest samples, the amount of C remaining with respect to time will be an excellent approximation of an exponential decay curve.

The actual underlying assumption is that, if those requirements have not been met, there is no reason for the data points to talk origins radioactive dating on a line. Bishop James Ussher, a 17th-century Irish cleric, for example, calculated that creation occurred in B.

The barrel represents the earth's atmosphere in which the carbon accumulates. Over time, the amounts of Pb and Pb will change in some samples, as these isotopes are decay end-products of uranium decay U decays to Pb, and U decays to Pb The data form an isochron indicating an age for Juvinas of 4.

A Close Look at Dr. Hovind's List of Young-Earth Arguments and Other Claims

A young-Earther would object to all of the "assumptions" listed above. Thus, even if Slusher and Rybka were correct--which they are not--the measured age of the Earth would still exceed 4 billion years. A study in the s showed that the decrease in the dipole component since the turn of the century had been nearly completely compensated by an increase in the strength of the nondipole components of the field. Even before the tree-ring calibration data were available to them, he and the archeologist, Evzen Neustupny, were able to suggest how much this would affect the radiocarbon dates.

Radiometric ages on related formations indicate that the Pahrump diabase is about 1.

Claim CD001:

Most creationist criticisms of radiometric dating can be categorized into a few groups. Pergamon Press, pp.

Rybka also explores the consequences of a hypothetical change over time of the decay constant, but his results are due solely to his arbitrary changes in the decay formula — changes for which there is neither a theoretical basis nor a shred of physical evidence.
