Rebuttals To Presented AIG Evidence Answers In Genesis: What Young Earth Creationism Gets Wrong

In addition, a rock melt does not
contain isotopic end members that can be mechanically mixed in
different proportions into the various minerals as they form, nor
could such end members be preserved if they were injected into a
melt. The data Morris
(92) refers to were published by Evernden and others
(44), but include samples from different islands that formed at
different times! The age of 3.34 million years is from the Napali
Formation on the Island of Kauai and is consistent with other
ages on this formation (86, 87). The approximate age of 250,000 years was the mean of the
results from four samples from the Island of Hawaii, which is
much younger than Kauai. Contrary to Morris’ concerns,
nothing is amiss with these data, and the statistical reasoning
used by Evernden and his colleagues is perfectly rational and
orthodox. But using argon-argon dating on tiny crystals in layers of volcanic ash sandwiching the sediments where Lucy was found, researchers have put the fossils at 3.18 million years old.

Panspermia involves the transportation of microorganisms throughout space, by dust, meteoroids, asteroids, comets, planetoids, or spacecraft. Though there is an error of +/- 70 million years in their calculation, the estimated age of the Earth still remains in textbooks even more than 60 years later after their publications. It seems that life thrives even in the harshest conditions; however, consider this, over five billion of all species of life forms evolved on Earth, and 99% of them are now extinct.

Putting
it another way, the “glue” holding the nucleus
together is extremely effective, and the nucleus is well
insulated from the external world by the electron cloud
surrounding every atom. This combination of the strength of
nuclear binding and the insulation https://yourhookupguide.com/pinkcupid-review/ of the nucleus is the reason
why scientists must use powerful accelerators or atomic reactors
to penetrate and induce changes in the nuclei of
atoms. The two ages
from gulf coast localities (Table 2) are from a report by
Evernden and others (43).

Do we mean the age of the solar system, or of the earth as a planet within it, or of the earth-moon system, or the time since formation of the earth’s metallic core, or the time since formation of the earliest solid crust? Such questions remain under active investigation, using as clues variations in isotopic distribution, or anomalies in mineral composition, that tell the story of the formation and decay of long-vanished short-lived isotopes. Isotopic ratios between stable isotopes both on the earth and in meteorites are coming under increasingly close scrutiny, to see what they can tell us about the ultimate sources of the very atoms that make up our planet.

If the amount of radiation to which an object is exposed remains constant, the amount of electrons trapped in the imperfections in the crystal structure of the material will be proportional to the age of the material. These methods are applicable to materials that are up to about 100,000 years old. However, once rocks or fossils become much older than that, all of the “traps” in the crystal structures become full and no more electrons can accumulate, even if they are dislodged. Each method makes several basic assumptions.2 First and foremost, each method assumes that the radioisotope decay rate has never changed during a rock’s entire existence. Second, each method has to assume a starting amount of both parent and daughter isotopes.

It was French physicist Becquerel who discovered in 1895 that nuclei of certain elements are inherently unstable and are actually in a process of spontaneous disintegration at a constant race to form stable end products. The principles of original horizontality, superposition, and cross-cutting relationships allow events to be ordered at a single location. However, they do not reveal the relative ages of rocks preserved in two different areas.

Isochron dating is supposed to remove the assumption
of initial conditions, but some different assumptions are
necessary. If radiometric dating techniques are objective
and accurate, then comparing the single–sample dates to
the isochron dates should give similar results. In the RATE
report there were dates that differed by up to a billion years. One volcanic rock layer from the top of Grand Canyon was
dated 270 million years older than the oldest rocks below it
near the bottom of the canyon. Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks.

The wet conditions would explain how sedimentary rock can be folded as so. The ratio of radioactive Potassium‑40 to its daughter product, Argon‑14, is measured in rock samples to determine the number of half-lives that have passed. Unfortunately, these elements don’t exist in dinosaur fossils themselves.

What is radiometric dating best used on?

But as potassium-40 decays, the argon-40 content will increase, and presumably remain trapped inside the now-solid rock. So, by comparing the argon-40 to potassium-40 ratio in a volcanic rock, we should be able to estimate the time since the rock formed. The half-life of potassium is 1.25 billion years, making this technique useful for dating rock samples ranging from about 100,000 years ago (during the age of early humans) to around 4.3 billion years ago. Potassium is very abundant in the Earth, making it great for dating because it is found in some levels in most kinds of samples.

How old is the Earth according to radiometric dating?

When this occurs, an unstable isotope becomes a more stable isotope of another element. That takes us to the end of this series of papers but not to the end of the story. As with so many good scientific puzzles, the question of the age of the earth resolves itself on more rigorous examination into distinct components.

This is because uranium decayed or changed into lead at such a slow rate that it was not reliable for measuring the age of rocks that were younger than 10,000,000 years old. A later method that used rubidium (which changes into strontium) proved more useful because it is found in nearly all rocks, although it still was not useful for younger specimens. Perhaps the best method for rock dating is the potassium-argon method. This method proved useful to date rocks as young as 50,000 years old.

Understand how decay and half life work to enable radiometric dating. Play a game that tests your ability to match the percentage of the dating element that remains to the age of the object. It is assumption 3, however, that must be incorrect if we are to present a convincing scientific argument that life on earth is not older than the Biblical account says it is.
