Ages of millions of years are all calculated by assuming the rates of change of processes in the past were the same as we observe today—called the principle of uniformitarianism. The solar system contains rocky asteroids and icy comets 4. It is the only model that has any hope of explaining a long-term magnetic field, so this reasoning is circular assuming the long ages, the dynamo model is 'best'. That is, in the past, uranium-238 transformed into lead-206 much faster than it does today. The radioactive parent elements used to date rocks and minerals are: Parent Daughter Half-life Uranium-235 Lead-207 0. Thus, the geologic timescale and radiometric dating have been developed in an effort to determine the age of the earth. In the early church, these estimates were provided by Cyprian, Irenaeus, Clement of Alexander, Julius Africanus, Origen, Lactantius, Chrysostom, Jerome, and Augustine, all of whom put the age of the earth at less than 6,000 years from the date of his writing.
I also appreciate your knowledge of the fallacies of arguing and how to structure your argument as to not invalidate it. To estimate a radioisotope age of a crystalline rock, geologists measure the ratio between radioactive parent and stable daughter products in the rock. Certain fossils are unique to certain layers of rock. Overview of Radiometric Dating Fossil remains are found in sedimentary rock layers. Creation Research Quarterly 25 3 :130—137, 1988.
A Geologic Time Scale: 1982 edition. You did not read very far if you did not find the articles from mainstream literature that are the source of much of the evidence. Meteorites During its history, the earth has suffered constant change. Isochron dating has been developed in an attempt to solve such problems. However, silicate inclusions in several iron meteorites have been dated by the K-Ar method at 4.
I was overwhelmed by the very long list of evidences. The C-14 in the plant or animal will begin to decay back to normal nitrogen. Each one has a different half-life and a different range of ages it is supposed to be used for. Multiple measurements chemical signature of ocean sediments, satellite penetration detectors, microcratering rate of objects left exposed on the lunar surface all agree on approximately the same value -- nearly three orders of magnitude lower than the value which Morris chose to use. Roman poet Lucretius, intellectual heir to the Greek atomists, believed its formation must have been relatively recent, given that there were no records going back beyond the Trojan War.
Thus, the earth itself has no direct evidence for its vast evolutionary age assignment. If you had read the linked articles you would understand that it is decay in the total energy of the magnetic field that is under discussion, which has nothing to do with the direction of the field. The first is to search for and date the oldest rocks exposed on the surface of the Earth. It does ensure that work toes the line of scientific orthodoxy, such that maverick ideas, upon which progress depends, are difficult to get published. If the age calculated from such assumptions disagrees with what they think the age should be, they conclude that their assumptions did not apply in this case, and adjust them accordingly. In other words, the half-life of carbon-14 is 5730 years, and there is nothing you can do to change it.
Within the creation theoretical system, different assumptions are used, producing different results. If Io had been erupting over 4. The result is that these dating methods only produce old ages for the within the evolutionary theoretical system. Greenland boasts the Isua supracrustal rocks 3. If life has evolved, then Earth must be very old. Very little is shown as stable.
As with so many good scientific puzzles, the question of the age of the earth resolves itself on more rigorous examination into distinct components. These physicists argue that the speed of light has been slowing down, affecting the rate of radioactive decay. Be aware that this article is not static. The evidence for the standard model of the formation of our solar system is quite robust There are many pieces of evidence to support the Nebular Hypothesis: 1. Also, a number of the evidences, rather than giving any estimate of age, challenge the assumption of slow-and-gradual uniformitarianism, upon which all deep-time dating methods depend. We must assume some starting condition.
An age is then transferred to the specimen of rock containing the measured elements. We would, obviously, have to assume that the candle has always burned at the same rate, and assume an initial height of the candle. In summary, it would need a neutron flux many orders of magnitude stronger than observed today. First, they tend to think that scientists can measure age. This involves measurement of three isotopes of lead Pb-206, Pb-207, and either Pb-208 or Pb-204.
