See this page in: Hungarian , Russian , Spanish People who ask about carbon 14C dating usually want to know about the radiometric  dating methods that are claimed to give millions and billions of years—carbon dating can only give thousands of years. People wonder how millions of years could be squeezed into the biblical account of history. Clearly, such huge time periods cannot be fitted into the Bible without compromising what the Bible says about the goodness of God and the origin of sin, death and suffering —the reason Jesus came into the world See Six Days? Christians , by definition, take the statements of Jesus Christ seriously. This only makes sense with a time-line beginning with the creation week thousands of years ago. It makes no sense at all if man appeared at the end of billions of years. We will deal with carbon dating first and then with the other dating methods. How the carbon clock works Carbon has unique properties that are essential for life on Earth. One rare form has atoms that are 14 times as heavy as hydrogen atoms:
Radioisotopes and the Age of the Earth (RATE)
See this page in: Russian How old is planet Earth? There are enormous differences of opinion. The most common view is that Earth is approximately 4.
Genesis There are three assumptions used when scientists measure ages with the radiometric dating process. The initial conditions of the fossil are known. In other words, the scientist assumes that neither the parent nor the daughter atoms have ever been altered outside of the decaying process since the formation of the fossil. The rate of decay has always been constant. This goes back to the idea of uniformitarianism , which is strongly adhered to by those who study historical science.
The rate of decay could have been faster or slower in the past due to numerous factors. There has been no contamination of the elements. None of the atoms have leached out of the fossil, and none of the atoms have been added to the fossil. Helium, for example, is known to leach out of a specimen. Uranium and lead are leached by ground water.
Age Dating the Earth
How accurate are carbon-dating methods? All methods of radioactive dating rely on three assumptions that may not necessarily be true: Rate of Decay It is assumed that the rate of decay has remained constant over time.
How Creationists Misrepresent the Carbon Dating Method By Dr. Robert Holloway home. In the continuing disagreement between religious fundamentalists and mainstream science, the subject of various dating methods is often discussed.
For example, Woodmorappe p. Because Woodmorappe doesn’t list Swisher et al. In another example, Woodmorappe p. The difference between Renne’s and Dalrymple’s dates are about Ma and Woodmorappe ridicules their efforts. So, again, Woodmorappe p. In yet another example among many, Woodmorappe p. In misquoting Peterson, Woodmorappe p. No matter what the cause, the discrepant sixth date of As usual, Woodmorappe p.
Numerous other examples may be cited, where Woodmorappe gives the impression of large inconsistencies between radiometric dates, whereas the original literature indicates that the inconsistencies are minor Baksi et al.
Tackling the “assumptions” of radiometric 1.
Rocks and fossils do not come with dates on them. In fact, the very concept of strata representing long ages does not come from the rock strata themselves. That concept began with eighteenth-century French naturalist Georges Cuvier, picked up steam with Charles Lyell, and it has been in vogue ever since. This is despite the fact that it causes more problems for interpreting rock strata than it solves.
Feb 13, · Ok, so this is the first of a three part series, tackling the “big 3 assumptions” that are often cited as “evidence” against radiometric dating. Those 3 assumptions are: 1. Scientists assume the initial quantities of parent and daughter isotopes 2. Scientists assume the rock being tested has.
Therefore it should come as no surprise that creationists at the Institute for Creation Research ICR have been trying desperately to discredit this method for years. They have their work cut out for them, however, because radiocarbon C dating is one of the most reliable of all the radiometric dating methods. This article will answer several of the most common creationist attacks on carbon dating, using the question-answer format that has proved so useful to lecturers and debaters.
How does carbon dating work? Cosmic rays in the upper atmosphere are constantly converting the isotope nitrogen N into carbon C or radiocarbon. Living organisms are constantly incorporating this C into their bodies along with other carbon isotopes. When the organisms die, they stop incorporating new C , and the old C starts to decay back into N by emitting beta particles.
The older an organism’s remains are, the less beta radiation it emits because its C is steadily dwindling at a predictable rate. So, if we measure the rate of beta decay in an organic sample, we can calculate how old the sample is. C decays with a half-life of 5, years.
The Age of the Earth
There are lots of ways to guesstimate ages, and geologists knew the earth was old a long time ago and I might add that they were mostly Christian creationist geologists. But they didn’t know how old. Radiometric dating actually allows the measurement of absolute ages, and so it is deadly to the argument that the earth cannot be more than 10, years old. Radiometric methods measure the time elapsed since the particular radiometric clock was reset. Radiocarbon dating, which is probably best known in the general public, works only on things that were once alive and are now dead.
It measures the time elapsed since death, but is limited in scale to no more than about 50, years ago. Generally applied to igneous rocks those of volcanic origin , they measure the time since the molten rock solidified. If that happens to be longer than 10, years, then the idea of a young-Earth is called into question. If that happens to be billions of years, then the young-Earth is in big trouble.
As of January, , The oldest rocks found on earth are 4. This is reported in the paper Priscoan 4. Williams; Contributions to Mineralogy and Petrology 1: The previous record was 3.
What are the assumptions used with radiometric dating?
Assumptions[ edit ] Standard linear regression models with standard estimation techniques make a number of assumptions about the predictor variables, the response variables and their relationship. Numerous extensions have been developed that allow each of these assumptions to be relaxed i. Generally these extensions make the estimation procedure more complex and time-consuming, and may also require more data in order to produce an equally precise model.
Example of a cubic polynomial regression, which is a type of linear regression. The following are the major assumptions made by standard linear regression models with standard estimation techniques e.

The Truth About Dating Methods
Reference to a case where the given method did not work This is perhaps the most common objection of all. Creationists point to instances where a given method produced a result that is clearly wrong, and then argue that therefore all such dates may be ignored. Such an argument fails on two counts:
Also, different radiometric dating techniques independently converges with each other and with other dating techniques such as dendrochronology, layers in sediment, growth rings on corals, rhythmic layering of ice in glaciers, magnetostratigraphy, fission tracks and many other methods.
Carbon atoms are incorporated into plant tissue by photosynthesis then into animal tissue by ingestion in nearly the same ratio as in the atmosphere. After that, the ratio of 14C to 12C decreases as the radiocarbon decays. The Beta-counting method detects the rate at which purified carbon decays. Libby determined, one gram of pure carbon should produce about 14 However, atmospheric testing of nuclear weapons in the late ‘s and early ‘s greatly increased the amount of radiocarbon in the atmosphere, so the decay rate of 14 decays per minute more than doubled.
Therefore, radiocarbon dates are calculated to a “pre-bomb” age of A. This bomb radiocarbon has been gradually removed from the atmosphere by by natural processes, but the “bomb spike” can be shown through the dating by means such as comparing the bottle date and radiocarbon age of wines.
Evolution’s Radiometric Dating Methods: Are they accurate?
Robert Holloway home In the continuing disagreement between religious fundamentalists and mainstream science, the subject of various dating methods is often discussed. Typically, fundamentalists are upset by the implications of the scientific dating methods since these methods often show an earth must older than the fundamentalists are willing to accept. Even the radiocarbon method often comes in for criticism although it is suitable only for objects less than 50, years old.
This criticism usually comes from Young Earth Creationists who believe that the earth is less than 10, years old.
List several methods of dating the earth that support a young earth. water formation, volcanism, metoric dust, soil formation What assumptions must be made when using the radiocarbon dating method?
The Potassium Argon Reaction Ar 40 is used for several reasons. First of all, Argon is inert. It does not chemically react with other elements at all. So Argon does not attach itself to the rock or any minerals in the rock. Secondly, Argon is usually a gas. These features are thought to allow any naturally occurring Argon from contaminating our measurements of the Argon 40 that is being produced from the radioactive decay of K When volcanic material flows over the land, the naturally occurring Argon gas is driven off by the excess heat.
When the rock is molten hot, it is more liquid in texture, allowing the Argon gas to escape. If all the gas is driven off, then there should be no Argon left in the rock. Once the rock cools and hardens, it is considered to be a closed system, because any new Ar 40 that is produced by the breakdown of K40 is trapped inside the rock crystal and cannot get out. So the scientist assumes that he or she is able to measure only that Ar 40 which is produced from K 40 since the rock has cooled.
