Lisle Oct 27, Geology , Origins , Physics. We are told that scientists use a technique called radiometric dating to measure the age of rocks. We are also told that this method very reliably and consistently yields ages of millions to billions of years, thereby establishing beyond question that the earth is immensely old - a concept known as deep time. This apparently contradicts the biblical record in which we read that God created in six days, with Adam being made on the sixth day. From the listed genealogies, the creation of the universe happened about years ago. Has science therefore disproved the Bible?

Another half-life reduces the amount to one-eighth, then one-sixteenth and so on.
The substance never quite vanishes completely, until we get down to one atom, which decays after a random time. Since the rate at which various radioactive substances decay has been measured and is well known for many substances, it is tempting to use the amounts of these substances as a proxy for the age of a volcanic rock.
After 1. So, if you happened to find a rock with 1 microgram of potassium and a small amount of argon, would you conclude that the rock is 1. If so, what assumptions have you made? In the previous hypothetical example, one assumption is that all the argon was produced from the radioactive decay of potassium But is this really known?
How do you know for certain that the rock was not made last Thursday, already containing significant amounts of argon and with only 1 microgram of potassium? In a laboratory, it is possible to make a rock with virtually any composition. Ultimately, we cannot know.
Creation Radiometric Dating and the Age of the Earth
But there is a seemingly good reason to think that virtually all the argon contained within a rock is indeed the product of radioactive decay. Volcanic rocks are formed when the lava or magma cools and hardens. But argon is a gas. Since lava is a liquid, any argon gas should easily flow upward through it and escape. Thus, when the rock first forms, it should have virtually no argon gas within it. But as potassium decays, the argon content will increase, and presumably remain trapped inside the now-solid rock.
So, by comparing the argon to potassium ratio in a volcanic rock, we should be able to estimate the time since the rock formed. This is called a model-age method. In this type of method, we have good theoretical reasons to assume at least one of the initial conditions of the rock.
The initial amount of argon when the rock has first hardened should be close to zero. Yet we know that this assumption is not always true. We know this because we have tested the potassium-argon method on recent rocks whose age is historically known. That is, brand new rocks that formed from recent volcanic eruptions such as Mt.
Helens have been age-dated using the potassium-argon method. Their estimated ages were reported as hundreds of thousands of years based on the argon content, even though the true age was less than 10 years. Since the method has been shown to fail on rocks whose age is known, would it make sense to trust the method on rocks of unknown age? But many secular scientists continue to trust the potassium-argon model-age method on rocks of unknown age.
If so, then their true ages are much less than their radiometric age estimates. The age estimate could be wrong by a factor of hundreds of thousands.
But how would you know?
We must also note that rocks are not completely solid, but porous. And gas can indeed move through rocks, albeit rather slowly. So the assumption that all the produced argon will remain trapped in the rock is almost certainly wrong. And it is also possible for argon to diffuse into the rock of course, depending on the relative concentration.
So the system is not as closed as secularists would like to think. There are some mathematical methods by which scientists attempt to estimate the initial quantity of elements in a rock, so that they can compensate for elements like argon that might have been present when the rock first formed.
Such techniques are called isochron methods. They are mathematically clever, and we may explore them in a future article. However, like the model-age method, they are known to give incorrect answers when applied to rocks of known age. And neither the model-age method nor the isochron method are able to assess the assumption that the decay rate is uniform.
As we will see below, this assumption is very dubious. Years ago, a group of creation scientists set out to explore the question of why radiometric dating methods give inflated age estimates. We know they do because of the aforementioned tests on rocks whose origins were observed.
But why? Which of the three main assumptions initial conditions are known, rate of decay is known, the system is close is false? To answer this question, several creation geologists and physicists came together to form the RATE research initiative R adioisotopes and the A ge of T he E arth. This multi-year research project engaged in several different avenues of study, and found some fascinating results.
As mentioned above, the isochron method uses some mathematical techniques in an attempt to estimate the initial conditions and assess the closed-ness of the system. However, neither it nor the model-age method allow for the possibility that radioactive decay might have occurred at a different rate in the past. In other words, all radiometric dating methods assume that the half-life of any given radioactive element has always been the same as it is today.
If that assumption is false, then all radiometric age estimates will be unreliable. As it turns out, there is compelling evidence that the half-lives of certain slow-decaying radioactive elements were much smaller in the past. This may be the main reason why radiometric dating often gives vastly inflated age estimates. First, a bit of background information is in order.
Most physicists had assumed that radioactive half-lives have always been what they are today. Many experiments have confirmed that most forms of radioactive decay are independent of temperature, pressure, external environment, etc. In other words, the half-life of carbon is years, and there is nothing you can do to change it. Given the impossibility of altering these half-lives in a laboratory, it made sense for scientists to assume that such half-lives have always been the same throughout earth history.
But we now know that this is wrong. In fact, it is very wrong.
More recently, scientists have been able to change the half-lives of some forms of radioactive decay in a laboratory by drastic amounts. However, by ionizing the Rhenium removing all its electronsscientists were able to reduce the half-life to only 33 years!
In other words, the Rhenium decays over 1 billion times faster under such conditions. Thus, any age estimates based on Rhenium-Osmium decay may be vastly inflated.
The RATE research initiative found compelling evidence that other radioactive elements also had much shorter half-lives in the past.
Several lines of evidence suggest this. But for brevity and clarity, I will mention only one. This involves the decay of uranium into lead Unlike the potassium-argon decay, the uranium-lead decay is not a one-step process.
Rather, it is a step process. Uranium decays into thorium, which is also radioactive and decays into polonium, which decays into uranium, and so on, eventually resulting in lead, which is stable. Eight of these fourteen decays release an alpha-particle: the nucleus of a helium atom which consists of two protons and two neutrons. The helium nucleus quickly attracts a couple of electrons from the environment to become a neutral helium atom.
So, for every one atom of uranium that converts into lead, eight helium atoms are produced. Helium gas is therefore a byproduct of uranium decay.
And since helium is a gas, it can leak through the rocks and will eventually escape into the atmosphere. The RATE scientists measured the rate at which helium escapes, and it is fairly high.
How Old is that Rock?
Therefore, if the rocks were billions of years old, the helium would have had plenty of time to escape, and there would be very little helium in the rocks. However, the RATE team found that rocks have a great deal of helium within them.
In fact, the amount of helium in the rocks is perfectly consistent with their biblical age of a few thousand years! It is wildly inconsistent with billions of years.
But the fact that such helium is present also indicates that a great deal of radioactive decay has happened; a lot of uranium atoms have decayed into lead, producing the helium. At the current half-life of uranium, this would take billions of years. But if it actually took billions of years, then the helium would have escaped the rocks. The only reasonable explanation that fits all the data is that the half-life of uranium was much smaller in the past. That is, in the past, uranium transformed into lead much faster than it does today.
The RATE team found similar evidence for other forms of radioactive decay. Apparently, during the creation week and possibly during the year of the global flood, radioactive decay rates were much faster than they are today.
The RATE team also found that the acceleration of radioactive decay was greater for elements with longer half-lives, and less for elements with shorter half-lives. All radiometric dating methods used on rocks assume that the half-life of the decay has always been what it is today. But we now have compelling evidence that this assumption is false. And since the decay rate was much faster in the past, those who do not compensate for this will end up with age-estimates that are vastly inflated from the true age of the rock.
This of course is exactly what we observe.

Oct 27, "Science has proved that the earth is billion years old." We have all heard this claim. We are told that scientists use a technique called radiometric dating to measure the age of rocks. We are also told that this method very reliably and consistently yields ages of millions to billions of years, thereby establishing beyond question that the earth is immensely old - a concept known.
We already knew that radiometric dating tends to give ages that are much older than the true age. Now we know why. For whatever reason, many people have the false impression that carbon dating is what secular scientists use to estimate the age of earth rocks at billions of years. Carbon dating is not used on rocks, because rocks do not have much carbon in them.
And with a half-life of only years, carbon does not last long enough to give an age estimate if something were truly millions of years old. All the carbon would be gone after one million years. To estimate the ages of rocks, secular scientists use elements with much longer half-lives, such as uranium, potassium, and rubidium Animals and plants contain abundant carbon.
Carbon dating is therefore used most frequently on animal or plant remains. The method gives an estimation of how long ago the organism died. Most carbon is c; the nucleus contains six protons and six neutrons.
Carbon is stable. A small fraction of carbon is c, which contains eight neutrons rather than six. Carbon is produced in the upper atmosphere when cosmic rays produce neutrons that interact with nitrogen atoms, converting them to c The c naturally decays back into nitrogen with a half-life of years. Animals then eat the plants, by which c is integrated into their body.

Matthews, Ph.D. [Click here for a summary of this article.]. Before , ages for the Earth based on uranium/thorium/lead ratios were generally about a billion years younger than the currently popular billion years.
So all plants, animals, and people have a small, but measurable quantity of c in their body. That c is slowly but continually decaying into nitrogen.
But, while alive, plants and animals replenish the c by taking in additional carbon from their environment. Therefore, the ratio of c to c in a living animal or plant is roughly the same as it is in the atmosphere. But when an organism dies, it ceases to replenish its supply of c The c simply decays, and therefore the c to c ratio in a dead organism will be somewhat less than that of the atmosphere. The older the organism, the lower the ratio. So, the ratio of c to c in animal or plant remains serves as a proxy for age, and can be used to estimate how long ago the organism died.
Unlike rock-dating methods, carbon-dating tends to give the correct answer when tested on material whose age is known. We therefore have more confidence in carbon-dating methods than we do in these other methods, though none are perfect of course.
