It is interesting that you chose an article that is 20 years old and then assert that AiG should update its article database. As you should know, the models that AiG uses change as we recognize their shortcomings and new data comes to light. As a result, more recent articles will reflect the current thinking. One example would come from my book, the fourth chapter is available on the AiG page today and deals with that very topic. However, the basic argument is the same, as you noted. We have a very clear bias and we found that on our understanding of the Bible and its authority. The techniques involved in radiometric dating including sampling, extraction, isolation, AMS, etc. These generate data that must be interpreted to arrive at a date. We do not dispute the techniques—we employ them to test samples ourselves.

Some updates to this article are now available. The sections on the branching ratio and dating meteorites need updating. Radiometric dating methods estimate the age of rocks using calculations based on the decay rates of radioactive elements such as uranium, strontium, and potassium. On the surface, radiometric dating methods appear to give powerful support to the statement that life has existed on the earth for hundreds of millions, even billions, of years.
We are told that these methods are accurate to a few percent, and that there are many different methods. We are told that of all the radiometric dates that are measured, only a few percent are anomalous. This gives us the impression that all but a small percentage of the dates computed by radiometric methods agree with the assumed ages of the rocks in which they are found, and that all of these various methods almost always give ages that agree with each other to within a few percentage points.
Since there doesn’t seem to be any systematic error that could cause so many methods to agree with each other so often, it seems that there is no other rational conclusion than to accept these dates as accurate. However, this causes a problem for those who believe based on the Bible that life has only existed on the earth for a few thousand years, since fossils are found in rocks that are dated to be over million years old by radiometric methods, and some fossils are found in rocks that are dated to be billions of years old.
In the first place, Creationists argue that methods of radiometric dating employ One common method of radioactive dating, the potassium-argon method, In addition, the Creationist arguments most commonly trotted out share a simple flaw.
Creationist’s Blind Dates. The standard scientific estimate is that the universe is about 15 billion years old, the earth about 4. It is important to recognize from the start that there are independent procedures for obtaining each of these estimates, and that the procedures yield ranges of values that overlap.
In the case of the universe, estimates can be obtained from astronomical methods or considerations of nuclear reactions. Astrophysicists can measure the rate at which galaxies are receding and use these measurements to compute the time needed for the universe to expand to its present size. A second, independent, astronomical method is to use standard techniques to measure some parameters of stars mass, luminosity, compositor, and surface temperature , from which a well-confirmed theory of the life histories of stars enables physicists to compute their.
Finally, considerations of radioactive decay make it possible to calculate the time at which certain heavy elements were formed. These techniques are somewhat similar to the radiometric methods of dating rocks, which I shad consider in a little more detail.
The mineral zircon adds three more fundamental advantages to uranium—lead dating. First, its crystal structure allows a small amount of tetravalent uranium to substitute for zirconium but excludes with great efficiency the incorporation of lead. It might be said that one begins with an empty box. Second, zircon, once formed, is highly resistant to change and has the highest blocking temperature ever observed. Finally, with few predictable exceptions, zircon grows or regrows only in liquid rock or in solid rock reheated to approach its melting point.
Combining all of these attributes, it is often possible to measure both the time of crystallization and the time of second melting in different parts of the same grain or in different selected grains from the same rock.
Potassium argon dating is used in our lives to date rocks/minerals that we find and can help us learn about our past. For example if an object is found.
An oversight in a radioisotope dating technique used to date everything from meteorites to geologic samples means that scientists have likely overestimated the age of many samples, according to new research from North Carolina State University. To conduct radioisotope dating, scientists evaluate the concentration of isotopes in a material.
The number of protons in an atom determines which element it is, while the number of neutrons determines which isotope it is. For example, strontium has 38 protons and 48 neutrons, whereas strontium has 38 protons and 49 neutrons. Radioactive elements, such as rubidium but not strontium or strontium , decay over time. By evaluating the concentrations of all of these isotopes in a rock sample, scientists can determine what its original make-up of strontium and rubidium were.
Then, by assessing the isotope concentrations of rubidium and strontium, scientists can back-calculate to determine when the rock was formed. The three isotopes mentioned can be used for dating rock formations and meteorites; the method typically works best on igneous rocks. The data from radioisotope analysis tends to be somewhat scattered. This function is able to tell researchers how old a sample is.
The ratios of strontium to rubidium and strontium are thought to only be influenced by the radioactive decay of the rubidium into strontium
See this page in: Hungarian , Russian , Spanish. P eople who ask about carbon 14 C 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. He said,.

Simply stated, radiometric dating is a way of determining the age of a sample of material using the Method 3: Potassium-Argon Dating In general, such claims are revealed as flawed by what they don’t say more than by what they do say.
Potassium-Argon radiometric dating is used to establish dates of lava flows. The reality of water running through any sample on earth is a strong problem for any reliance on this dating method. Running water dilutes potassium levels rapidly which equates to artificially older dates on specimens. This equates to this dating method becoming invalid because running water is abundant and may occur anywhere on earth or in the unobserved past. Ask any farmer and they can tell you about the loss of potassium in soil because each year they have to drop fertilizer on their crops.
Dating methods that rely on a decay rate between parent and daughter with potassium are rendered invalid. Other potassium-argon dating errors. We know the true ages of flows observed to form less than 50 years ago. If the method fails on rocks when we have an independent eye-witness account, then why should we trust it on other rocks where there are no independent historical cross-checks? Argon gas, brought up from deep inside the earth within the molten rock, was already present in the lavas when they cooled.
We know the true ages of the rocks because they were observed to form less than 50 years ago. The K—Ar potassium-argon dating method is not usually used to date by radiometric methods fossils because these specimens rarely contain suitable radioactive elements. This is commonly done using the K—Ar method. It depends on the rate at which radioactive potassium decays into the gas argon.

Cambridge Lab Result. In ” Lies of Evolution: Geologic Column ,” we covered how the geologic column is made up from pure imagination, so what did the quote just tell us? They throw out an age they get if it doesn’t line up with their geologic column, or more simply put, they throw out a date they get if it doesn’t line up with how old they already think it is!
Let’s say an evolutionist gets radiometric dates of an object, and the lab will pull back all sorts of wild numbers, lets say ranging from. This is exactly how it’s done , and all of it comes down to the circular reasoning dating methods used for fossils dating rocks and rocks dating fossils. Many evolutionary scientists know radiometric dating does not work properly.
Evolutionists are dating objects based on the imaginary geologic column, not by any scientific method.
An Essay on Radiometric Dating. Radiometric dating methods are the strongest direct evidence that geologists have for the age of the Earth. All these methods point to Earth being very, very old — several billions of years old.
Potassium-Argon Dating Potassium-Argon dating is the only viable technique for dating very old archaeological materials. Geologists have used this method to date rocks as much as 4 billion years old. It is based on the fact that some of the radioactive isotope of Potassium, Potassium K ,decays to the gas Argon as Argon Ar By comparing the proportion of K to Ar in a sample of volcanic rock, and knowing the decay rate of K, the date that the rock formed can be determined. How Does the Reaction Work?
Potassium K is one of the most abundant elements in the Earth’s crust 2. One out of every 10, Potassium atoms is radioactive Potassium K These each have 19 protons and 21 neutrons in their nucleus. If one of these protons is hit by a beta particle, it can be converted into a neutron. With 18 protons and 22 neutrons, the atom has become Argon Ar , an inert gas. For every K atoms that decay, 11 become Ar How is the Atomic Clock Set?
When rocks are heated to the melting point, any Ar contained in them is released into the atmosphere.
