In this issue we will look at the isochron technique and at new research on Helium diffusion that gives an exciting confirmation of the Biblical age of the Earth. There are three key assumptions of radioactive dating techniques that have been called into question by young earth creationists. The First of these is that there is a constant decay rate of the radioactive elements. Creationists now have done their own experimental research that calls this assumption into question. The research on Helium diffusion in zircon crystals that follows is one line of evidence to that effect. Other major assumptions of radiometric dating are that the sample has been a closed system while the decay occurred and that the initial concentrations of the radioisotopes is known. In real rocks and minerals, the closed system assumption would mean that there was no non-radioactive process that changed the amounts of the radioactive elements while the radioactive decay was taking place. This assumption is seldom completely valid.
The Age of the Earth
Kuban last revised Jan. I use this format to avoid webbot spamming Fig. Brown’s website and book showing what he calls the “Rupture Phase of the Flood” Introduction Walter Brown, a young-earth creationist and retired mechanical engineer, has developed a “Flood model”1 which he believes accounts for virtually all geologic evidence on earth, as well as a variety of astronomical phenomena.
In addition, it is used as a component in deep-sea breathing systems, as a coolant for superconducting magnets, and as a protective gas for many industrial processes such as arc welding and growing silicon wafers. Researchers use helium to study materials at very low temperatures, in a field called cryogenics, and in helium dating of radioactive rocks and minerals.
Inhaling a small volume of the gas temporarily changes the tonal quality and pitch of one’s voice. It can, however, be dangerous if done in excess. Abundance in nature Helium is the second most abundant element in the known universe, after hydrogen , constituting 23 percent of the elemental mass of the universe. It is concentrated in stars , where it is formed by two sets of nuclear fusion reactions: Based on this theory, the abundance of helium serves as a test of cosmological models. In the Earth’s atmosphere, the concentration of helium by volume is only 5.
In the Earth’s heterosphere a part of the upper atmosphere , helium and other lighter gases are the most abundant elements.
Isobaric Counter Diffusion
Biblical interpretation and some scientific studies indicate a young earth. Therefore, radioactive decay must have been accelerated by approximately a factor of one billion during the first three days of creation and during the flood. The concept of accelerated decay leads to two unresolved scientific problems, the heat problem and the radiation problem, though there is confidence that these will be solved in the future.
Third, many dating methods that don’t involve radioisotopes—such as helium diffusion, erosion, magnetic field decay, and original tissue fossils—conflict with radioisotope ages by .
Elements like uranium and thorium produce helium in zircons as a biproduct of their radioactivity. This helium seeps out of zircons quickly over a wide range of temperatures. If the zircons really are about 1. Accelerated decay must have produced a billion years worth of helium in that short amount of time. A Helium Diffusion Model Proposed As early as the s, Robert Gentry pointed out that rocks appeared to be retaining more Helium than they should using standard models.
Russell Humphreys , Steven Austin , Andrew Snelling , and John Baumgardner , the first three professors at the Institute for Creation Research and the last, a scientist at Los Alamos National Laboratory, conceived a model using what was known regarding helium diffusion in zircons. Their report  suggested that the amount of helium in the zircon was well over what would be observed in an old universe, citing a 5 order of magnitude error.
Following the scientific method , they used their model to predict a collection of diffusion rates at hitherto untested temperatures. Humphreys claims these predictions were validated in a separate experiment reported in his report . Kevin Henke, an instructor at the University of Kentucky, spent words challenging these results. Helium in the Atmosphere There is also insufficient mass of helium in earth’s atmosphere to account for 4.
Helium is a noble gas which doesn’t combine with any other element, but there is not enough of it to account for the radioactive decay which should have occurred in an old earth scenario. Malcolm Davis gives a careful treatment of the mathematics involved in calculating the rate at which helium escapes  , and notes that the rate at which Helium is being produced is thirty times higher than its rate of escape. If the earth were very old, much more Helium should have accumulated in the atmosphere.
Age of the earth
Exploring the wonders of geology in response to young-Earth claims Please read my guidelines and background posts before proceeding! Sunday, February 6, Clearest evidence that the Earth is 6, years old: In particular, I want you to consider whether AiG functions as a scientific research institution, given the manner in which they have promoted the results the study below as compelling evidence for a young Earth. By ignoring healthy criticism of their research and avoiding followup experiments, they have foregone a valuable opportunity to take part in the scientific community and instead reduced themselves to dogmatism.
What is the clearest evidence that the Earth is less than 10, years old?
Alpha decay releases a Helium nucleus (two protons and two neutrons) from the parent atom to create two atoms: the released Helium and a daughter product that has an atomic number two less than the original and an atomic mass four less than the original.
Would you like to merge this question into it? MERGE already exists as an alternate of this question. Would you like to make it the primary and merge this question into it? MERGE exists and is an alternate of. Merge this question into Split and merge into it SAVE In Elements and Compounds Helium diffusion in zircon is the movement of helium atoms that have been trapped within a zircon crystal matrix.
That may not make sense by itself, so let’s take a little trip through some background information to see if it can be made clearer. This might get a little long-winded, but it really isn’t that difficult to understand when taken in moderate bites. We’ve said grace, so tuck in your napkin and grab your fork. When rock crystals form, they essentially “trap” the materials of which they are made within the crystal matrix.
The atoms involved are usually trapped by both chemical bonding to other atoms and the physical restrictions of the matrix itself. Imagine a room full of people holding hand and having their arms interlocked in various ways.
Dr. Humphreys’ Young-Earth Helium Diffusion “Dates”
The Radiometric Dating Game 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.
Helium diffusion is one type of nuclear decay dealing with the emission of Helium nuclei known as an alpha emission. Elements like uranium and thorium produce helium in zircons as a biproduct of their helium seeps out of zircons quickly over a wide range of temperatures. If the zircons really are about billion years old (the age which conventional dating gives assuming a.
Evolutionists generally feel secure even in the face of compelling creationist arguments today because of their utter confidence in the geological time scale. Even if they cannot provide a naturalistic mechanism, they appeal to the “fact of evolution,” by which they mean an interpretation of earth history with a succession of different types of plants and animals in a drama spanning hundreds of millions of years.
The Bible, by contrast, paints a radically different picture of our planet’s history. In particular, it describes a time when God catastrophically destroyed the earth and essentially all its life. The only consistent way to interpret the geological record in light of this event is to understand that fossil-bearing rocks are the result of a massive global Flood that occurred only a few thousand years ago and lasted but a year. This Biblical interpretation of the rock record implies that the animals and plants preserved as fossils were all contemporaries.
This means trilobites, dinosaurs, and mammals all dwelled on the planet simultaneously, and they perished together in this world-destroying cataclysm. Although creationists have long pointed out the rock formations themselves testify unmistakably to water catastrophism on a global scale, evolutionists generally have ignored this testimony. This is partly due to the legacy of the doctrine of uniformitarianism passed down from one generation of geologists to the next since the time of Charles Lyell in the early nineteenth century.
Uniformitarianism assumes that the vast amount of geological change recorded in the rocks is the product of slow and uniform processes operating over an immense span of time, as opposed to a global cataclysm of the type described in the Bible and other ancient texts. With the discovery of radioactivity about a hundred years ago, evolutionists deeply committed to the uniformitarian outlook believed they finally had proof of the immense antiquity of the earth. In particular, they discovered the very slow nuclear decay rates of elements like Uranium while observing considerable amounts of the daughter products from such decay.
Drilling rig at Fenton Hill, NM, borehole from which zircons were taken. Most of his latest reply simply rehashes the issues to which I already replied, adding more words but less substance. However, he did bring up one new issue that is worth while to examine in detail — the possible effect of pressure including zero pressure, a vacuum on rates of helium diffusion leakage from the zircons while they were deep underground.
#6 Helium in Radioactive Rocks The fact that so much helium is still there means they cannot be billion years old, as uranium-lead dating suggests. Indeed, using the measured rate of helium diffusion, these pre-Flood rocks have an average “diffusion age” of only 6,
This essay contains additional evidence and discussions that demonstrate that Dr. Humphreys’ work is fatally flawed and never achieves its YEC objectives. Supposedly, in this revision, plainly-refuted points have been removed from this paper and this revision represents the latest, most complete counter in the world to this topic of helium diffusion in zircon. There does not seem to be a counter-counter-counter-counter paper by Humphreys or anyone else, so the counter-counter-counter paper by Henke stands as the last latest?
Either this paper is rock-solid in research and science, or nobody has bothered to refute it yet. Admittedly, this revision is less than a week old, so there has hardly been time to compose anything meaningful.
