Earth dating

Compston and R. Pidgeon Nature A serious problem here is that all crystals from the same rock unit gave statistically valid information about that rock unit. In fact, the other crystals show such a confusion of information that a statistician could only conclude that no sensible dates could be extracted from the data. A further problem is that the 4. An unbiased observer would be forced to admit that this contradiction prevents any conclusion as to the age of the crystal.

Compston and R. Pidgeon Nature A serious problem here is that all crystals from the same rock unit gave statistically valid information about that rock unit. In fact, the other crystals show such a confusion of information that a statistician could only conclude that no sensible dates could be extracted from the data. A further problem is that the 4. An unbiased observer would be forced to admit that this contradiction prevents any conclusion as to the age of the crystal.

But these authors reached their conclusion by ignoring the contradictory data! If a scientist in any other field did this he would never be allowed to publish it. Yet here we have it condoned by the top scientific journal in the world. This is not an isolated case. I selected it because it was identified by the journal editors as a significant advance in knowledge. Another example is the work of F. Podosek, J. Pier, O. Nitoh, S. Zashu, and M. Ozima Nature They extracted diamonds from rocks in Zaire and found by the potassium-argon method that they the diamonds were six billion years old.

But the earth is supposed to be only 4. So Podosek and friends decided they must be wrong. First, the dates are readily discarded if they do not fit the preconceived notions of the experimenter. Such a practice is not acceptable in any other field of science because it destroys the objectivity upon which science has built its reputation. Isotope dating is therefore not the objective, absolute dating method it is often claimed to be. Second, it is impossible to tell, from the isotope information alone, when the dates are right and when they are wrong.

But can you ride a bicycle into the past simply because no one else has a better time-machine? Of course not. In the same way it is absurd to argue that an inadequate method is adequate because nothing better is available. We have supplied this link to an article on an external website in good faith.

As far as better dating methods, we need a better way to counter the question, "Do you have a better method? Like a hunter shooting at a target beyond the range of his rifle, the fact he does not have a more powerful gun, does not mean he is wise to continue shooting uselessly at far distant targets which he cannot hit.

Tas Walker October 19th, Check this article on How dating methods work and other cited articles at the bottom. Kenneth L. After reading the CMI article referenced in the response to my second message, I have to say that I am even more confident that not only is it not impossible to determine the approximate age of the creation of granite basement rock by measuring in the present given the right method, i.

This is not to say that a day, year, century or even a millennium can yet be determined, but I believe they demonstrated that at least an age range that is orders of magnitude far below billions of years i. After answering I would even say invalidating numerous criticisms of the helium diffusion dating method over a period of years and having the data defended by the experimenter, I think Dr.

Humphreys and the RATE team are justified in putting the burden on the critics to invalidate the method as good science. The critics don't appear to have done so yet by a long shot, and unless or until they do it appears unlikely to happen , the helium diffusion dating method must be considered not only as valid science, but as a clearly superior dating method over radiometric dating of igneous rock. I would like to see the famous zircons from west Australia and other locations around the world be subjected to the clearly superior helium diffusion dating method.

Hi Dr. Walker, thanks for your response to my comment. I have great respect for your work in creation science and have learned much from it. But I do have a bone to pick on this one. I am aware of the assumptions that go into radiometric dating methods, and how those assumptions invalidate radio-dating as valid science, inasmuch as it claims to accurately date rocks when it clearly does not, given it is based on those unproved assumptions.

But what unproved assumptions is helium diffusion dating basing itself on? I am not aware of any. Is it not possible that God created the material world is such a way that there is a dating method that doesn't depend upon unproved assumptions, and that the RATE project found that method? If you can tell me any unproved assumption upon which helium diffusion in zircon crystals is based, I will concede that point and bow to your logic. But if not, I think YEC's are entitled to claim that RATE scientists have determined or rather verified, Scripture having already revealed the approximate age of the Earth from this dating method.

Otherwise, what was the point of doing the RATE research at all? It would seem to have been a waste of time and money, if we concede that there is no way other than Scripture to verify the age of the Earth. So again I ask, can we be sure there is no dating method other than radiometric that does not depend on unproved assumptions?

And if we assume that, why was helium diffusion dating performed by the RATE team? And why did it date granite samples at about years old? To me, given that this date agrees with Scripture and for other reasons , it would seem that this dating method is valid and does give true dates. You folks can publish this or not, as you see fit. I just want to stimulate some thought.

Tas Walker September 21st, Hi Kenneth, Thank you for your follow-up comment. In our article Age of the earth: The introduction to that article entitled "Can science prove the age of the earth? Namely, that it is not possible to measure the age of something by making measurements only in the present. There has been considerable controversy over the RATE results and the underlying assumptions have been questioned.

Helium evidence for a young world continues to confound critics. So we consider the evidence is still good evidence. When talking about this I don't say such and such an evidence proves the earth is young. I say that it is consistent with the young earth. Terry W. CA September 20th, Looking at the Kenneth L. The diffusion rate curve is far more likely to remain constant than radioactive decay rates which have been observed to change on a seasonal basis, although nowhere near what would be needed to jam 4.

The temperature history assumption is essentially a worst case scenario of the zircons being on the hot side of the diffusion curve's kink for the whole years. It would only need to be that hot for a puny fraction, say one thousandth, of the 4. It might not be the Space Shuttle, but at least we got some model rockets happening. Seathrun M. IE September 20th, Excellent article on the flaws of radiometric dating.

But no better dating method? What about helium diffusion in zircon crystals? Tas Walker September 20th, However, the fact is that it is impossible to determine the age of an event in the past by making observations and measurements only in the present. Every such age calculation depends on multiple assumptions, and is thus not objective. Anyone who disagrees with the result simply argues about the unobservable, unprovable assumptions.

Young earth creationists disagree with the assumptions of those who promote an old earth, and they in turn disagree with the assumptions of young-earth creationists. It is not something that can be settled by observations in the present. Check the article How dating methods work and the related article links at the bottom.

Age dating the Earth (Geochronology) is the scientific study of the age of the Earth and the temporal sequence of events related to the formation of the planet and. Using relative and radiometric dating methods, geologists are able to answer the Second, it is possible to determine the numerical age for fossils or earth.

Despite seeming like a relatively stable place, the Earth's surface has changed dramatically over the past 4. Mountains have been built and eroded, continents and oceans have moved great distances, and the Earth has fluctuated from being extremely cold and almost completely covered with ice to being very warm and ice-free. These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.

Age dating the Earth Geochronology is the scientific study of the age of the Earth and the temporal sequence of events related to the formation of the planet and the history of life on Earth. The word is derived from Geo meaning Earth , and chronology , which is the study of time, or a record of events in the order of their occurrence timeline. It is from this field of study that fossils and artifacts are dated based on the perceived age of the geological layers in which they are located.

Nineteenth century geologists recognized that rocks formed slowly as mountains eroded and sediments settled on the ocean floor. But they could not say just how long such processes had taken, and thus how old their fossils were. He came up with that figure by estimating how long it had taken for the planet to cool down to its current temperature from its molten infancy. But Kelvin didn't, and couldn't, know that radioactive atoms such as uranium were breaking down and keeping the planet warmer than it would be otherwise. An older Earth At the dawn of the twentieth century, physicists made a revolutionary discovery:

Age Dating the Earth

The age of the Earth is 4. Following the development of radiometric age-dating in the early 20th century, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old. It is hypothesised that the accretion of Earth began soon after the formation of the calcium-aluminium-rich inclusions and the meteorites. Because the time this accretion process took is not yet known, and predictions from different accretion models range from a few million up to about million years, the difference between the age of Earth and of the oldest rocks is difficult to determine. It is also difficult to determine the exact age of the oldest rocks on Earth, exposed at the surface, as they are aggregates of minerals of possibly different ages. Studies of strata , the layering of rocks and earth, gave naturalists an appreciation that Earth may have been through many changes during its existence. These layers often contained fossilized remains of unknown creatures, leading some to interpret a progression of organisms from layer to layer. Nicolas Steno in the 17th century was one of the first naturalists to appreciate the connection between fossil remains and strata. In the midth century, the naturalist Mikhail Lomonosov suggested that Earth had been created separately from, and several hundred thousand years before, the rest of the universe. Lomonosov's ideas were mostly speculative.

Flat-earthers are people who do not believe that the Earth is a sphere and that photographs of the planet taken from space are a hoax. The founder of the closed Facebook group, John Perri, said:

Most people accept the current old-earth OE age estimate of around 4. This age is obtained from radiometric dating and is assumed by evolutionists to provide a sufficiently long time-frame for Darwinian evolution. And OE Christians theistic evolutionists see no problem with this dating whilst still accepting biblical creation, see Radiometric Dating - A Christian Perspective.
