The following comprises a series of essays written in response to a discussion held on the Message Board of this web site. The discussion, between a young creationist, Rob, and several other regular contributors, eventually came to the issue of radio isotope dating. Rob mentioned that Steve Austin’s Grand Canyon dating experiment cast doubt on the viability of absolute dating systems. Naturally the notion was rebuffed and respondents pointed to articles heavily critical of the YEC experiment. Wanting to hear both sides of the issue, Rob wrote to Answers in Genesis, highlighting some particular lines written by Chris Stassen in an article critical of Austin’s Canyon work. The relevant lines were:. The conditions which caused the “false isochron” in this case are fairly well-understood, and easy to avoid by proper sample selection. In fact, the resulting age in this case is meaningful and probably accurate. The problem is not the age itself but rather Austin’s sleight-of-hand in trying to pass off the result as the age of the flows rather than a minimum age of their source.
How accurate are Carbon-14 and other radioactive dating methods?
NASA’s Genesis spacecraft spent more than two years collecting samples of the solar wind. The spacecraft then brought the sample cannister back to Earth where it parachuted to the ground. Despite a hard landing in the Utah desert, the Genesis samples were recovered. Genesis, the fifth Discovery-class spacecraft, was designed to collect samples of the solar wind and then bring them to Earth.
This figure is based on radiometric dating. Some creationists have attempted to reconcile this figure with the creation in Genesis by proposing that the rocky.
By Kirk Reynolds. The global flood as described in the Bible has been attacked by Christians as well as non-Christians. Those Christians who do not hold to a literal reading of Genesis are willing to believe in the old age of the earth as proposed by evolution. This belief states that the universe came into existence approximately 12 billion years ago through the Big Bang. There are several theories of creation based on this evolutionary timeline, such as Progressive Creation, Gap Theory, Framework Hypothesis, and Theistic Evolution.
None of these theories allow for the literal six-day creation as plainly contained in the Bible. In the case of Progressive Creation, it is believed that each day represents eons of time. The Framework Hypothesis mixes literal creation days with long periods of time. The Gap Theory argues that there is a gap between Genesis and which allows for a long period of time.
Finally, Theistic Evolution proposes that God used evolution in the creation process. All of these theories have in common a belief that the creation account given in Genesis 1 and 2 contain allegory and should not be taken literally.
2. Absolute age dating
O ver the past century of biblical archaeology, a plethora of finds have been discovered backing up many of the biblical stories. Thus far, nearly 60 individuals found in the Hebrew Bible have been independently proved through archaeological discoveries, including kings, pharaohs, princes, governors, officers and priests. Archaeology has confirmed dozens of biblical cities, as well as the biblical events that happened within them. It has verified everything from biblical civilizations and major conflicts to minor skirmishes, cultural customs, dietary details, clothing items, architectural elements and even common sayings.
Right here, we have countless book radiometric dating answers in genesis and collections to check out. We additionally present variant types and after that type.
Most people envision radiometric dating by analogy to sand grains in an hourglass: the grains fall at a known rate, so that the ratio of grains between top and bottom is always proportional to the time elapsed. In principle, the potassium-argon K-Ar decay system is no different. Of the naturally occurring isotopes of potassium, 40K is radioactive and decays into 40Ar at a precisely known rate, so that the ratio of 40K to 40Ar in minerals is always proportional to the time elapsed since the mineral formed [ Note: 40K is a potassium atom with an atomic mass of 40 units; 40Ar is an argon atom with an atomic mass of 40 units].
In theory, therefore, we can estimate the age of the mineral simply by measuring the relative abundances of each isotope. Over the past 60 years, potassium-argon dating has been extremely successful, particularly in dating the ocean floor and volcanic eruptions. K-Ar ages increase away from spreading ridges, just as we might expect, and recent volcanic eruptions yield very young dates, while older volcanic rocks yield very old dates.
Though we know that K-Ar dating works and is generally quite accurate, however, the method does have several limitations. First of all, the dating technique assumes that upon cooling, potassium-bearing minerals contain a very tiny amount of argon an amount equal to that in the atmosphere. While this assumption holds true in the vast majority of cases, excess argon can occasionally be trapped in the mineral when it crystallizes, causing the K-Ar model age to be a few hundred thousand to a few million years older than the actual cooling age.
Secondly , K-Ar dating assumes that very little or no argon or potassium was lost from the mineral since it formed.
Others had tried. But Drs Humphreys and Baumgardner realized that there were too many independent lines of evidence the variety of elements used in ‘standard’ radioisotope dating, mature uranium radiohalos, fission track dating and more that indicated that huge amounts of radioactive decay had actually taken place. It would be hard to imagine that geologic processes could explain all these. Rather, there was likely to be a single, unifying answer that concerned the nuclear decay processes themselves.
Comentarios desactivados. A country science ago, some radiometric creationist geologists and rebuttals began a detailed research project into R adioactivity and the A ge of T he E arth RATE. With the release of key peer-reviewed papers at the ICC International Conference on Genesis , it is clear that RATE has made some fantastic progress, with real breakthroughs in this area.
Others had tried to find an answer in geological processes—e. This is indeed country answer in some cases. It would be hard to imagine that geologic answers alone could explain all these. Rather, there was likely to be an genesis that rebuttals the nuclear decay processes themselves. So it was clear that the assumption of a constant, slow decay process was wrong. Radiometric is now radiometric confirmatory evidence that at least one episode of drastically accelerated genesis has indeed been the case, building on the work of Dr Robert Gentry on helium retention in zircons.
The paper dating at the various avenues a long-ager might creation by which to wriggle out of these powerful implications, but rebuttals seems to be little hope for them unless they can show that answers techniques used to obtain the results were seriously flawed.

Modern Science and a;ie Book of Genesis can help to bring about an Jim Skehan is offering such an answer in a scholarly but most readable fashion. records of near-Eastern peoples, we can date these traditions as far back as the tenth Scientists use the amounts of parent isotopes and daughter products.
Today, though, a friend of mine shared this youtube video from AiG about radiometric dating, and why it is supposedly unreliable for determining the age of rocks. Now, I am not a scientist, and most scientific discussion makes my eyes glaze over. My brain is wired for literature, poetry, and Biblical Studies. As I watched this short video, though, a few thoughts popped into my head that I just have to share. First, take minutes and watch for yourself.
Up to that mark, I was somewhat surprised: AiG gave a straightforward explanation regarding radiometric dating and half-life. Thanks AiG, for admitting that and for giving scientists a certain amount of credit and respect.

The RationalMedia Foundation board of trustees election is completed and the results are posted. Thank you for your interest and participation! Radiometric dating involves dating rocks or other objects by measuring the extent to which different radioactive isotopes or nuclei have decayed. Although the time at which any individual atom will decay cannot be forecast, the time in which any given percentage of a sample will decay can be calculated to varying degrees of accuracy.
The time that it takes for half of a sample to decay is known as the half life of the isotope. Some isotopes have half lives longer than the present age of the universe , but they are still subject to the same laws of quantum physics and will eventually decay, even if doing so at a time when all remaining atoms in the universe are separated by astronomical distances.
But for humans whose life span rarely reaches more than years, how can we be so sure of that ancient date? It turns out the answers are in Earth’s rocks. Even.
Many get fed up with Ken Ham and Answers in Genesis continually misrepresented normal science. This is a good summary of why his recent porkies are pure Ham. Isochron dating bypasses the necessity of knowing the quantity of initial daughter product in the rock by not using that value in the computation. Instead of using the initial quantity of daughter isotope, the ratio of daughter isotope compared to another isotope of the same element which is not the product of any decay process is used as the comparison for isochron dating.
The plot of the ratios of the number of atoms of the parent isotope to the number of atoms in the non-daughter isotope compared to the number of atoms of the daughter isotope to the non-daughter isotope should result in a straight line that intersects the vertical y-axis which is the ratio of daughter to non-daughter isotopes.
This point of intersection gives the initial ratio of daughter to non-daughter isotopes, which would also be the ratio in a mineral that crystallized without any parent isotope present. Here is a web site that shows how this plot works in graphic fashion. The decay rate is well-known and invariate, which leads to his second statement.
Such a perspective is facile, as it completely disregards the fact that we reconstruct past events every day at all levels, from the simple act of encountering a broken glass on the floor with ice and water beside it someone dropped a glass of water to complex murder investigations in which no one but the murderer was present. No one questions the validity of these assumptions and they form the basis for much of what we do in life, including our entire criminal justice system.
Secondary to this notion that we can reconstruct the past is that the processes that occur today also occurred in the past. If I am digging in a field and encounter, at a depth of three or so feet, a series of horizontal metal beams that are four and a half feet apart with ties in between them, because I know that distance is the standard railway gauge, I can reasonably assume that what I have uncovered is part of an old railway.
Was I there when they built it? This is true not just of human constructs but also of natural formations.
The Prehistoric World Vs. Genesis
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?
NASA’s Genesis spacecraft spent more than two years collecting samples of the solar wind. Launch Date and Time, Aug. They published results detailing, for example, the identification of argon and neon isotopes in samples of three Dawn spacecraft data answers two big questions: Is there liquid.
Geological time scale — 4. Geological maps. Absolute age dating deals with assigning actual dates in years before the present to geological events. Contrast this with relative age dating, which instead is concerned with determining the orders of events in Earth’s past. Scholars and naturalists, understandably, have long been interested in knowing the absolute age of the Earth, as well as other important geological events. In the ‘s, practitioners of the young science of geology applied the uniformitarian views of Hutton and Lyell see the introduction to this chapter to try to determine the age of the Earth.
For example, some geologists observed how long it took for a given amount of sediment say, a centimeter of sand to accumulate in a modern habitat, then applied this rate to the total known thickness of sedimentary rocks.
