Radiocarbon Dating & Calibration

Radiocarbon dating can easily establish that humans have been on the earth for over twenty thousand years, at least twice as long as creationists are willing to allow. 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. Answer: 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.

Voting for the RationalMedia Foundation board of trustees election is underway! The evidence against a recent creation is overwhelming. This article collects evidences that place a lower limit on the age of the Universe beyond the 6, to 10, years asserted by most Young Earth creationists YECs and the literalist Ussher chronology. All of this evidence supports deep time : the idea, considered credible by scientists since the early s, that the Earth and the Universe is millions [note 1] or billions of years old.

The primary dating methods that are used by secular scientists to show that the skeptical claims from an article by Mark Isaac on TalkOrigins, an evolutionary.

The consistency of decay rates gives us confidence in the probabilistic nature of half-life. Both are extremely reliable. The subtitle of this work was “An attempt to explain the former changes of the Earth’s surface by reference to causes now in operation. However, modern geology and biology have long since moved beyond these simple concepts, recognizing that while the earth’s history is a slow process of gradual change, this process has been punctuated by periodic natural catastrophic events.

For example, in the late twentieth century, J. Harlan Bretz demonstrated that the Scablands in eastern Washington state were formed from a large flood, which in turn resulted when a glacial lake broke through an ice dam. Similarly, in , Luis Alvarez proposed that an asteroid impact was responsible for the extinction of dinosaurs 65 million years ago. Radiometric Dating.

How Old is the Earth

There are at least 3 ways that the age of the Universe can be estimated. I will describe The age of the chemical elements. The age of the oldest star clusters. The age of the oldest white dwarf stars. The age of the Universe can also be estimated from a cosmological model based on the Hubble constant and the densities of matter and dark energy. This model-based age is currently

Other Links:. Former creationist Glenn Morton examines several famous young-earth creationist arguments and provides data to illustrate their flaws. A Radiometric Dating Resource List. Tim Thompson has collected a large set of links to web pages that discuss radiometric dating techniques and the age of the earth controversy. This value is derived from several different lines of evidence. Unfortunately, the age cannot be computed directly from material that is solely from the Earth.

There is evidence that energy from the Earth’s accumulation caused the surface to be molten. Further, the processes of erosion and crustal recycling have apparently destroyed all of the earliest surface. The oldest rocks which have been found so far on the Earth date to about 3. Some of these rocks are sedimentary, and include minerals which are themselves as old as 4. Rocks of this age are relatively rare, however rocks that are at least 3.

While these values do not compute an age for the Earth, they do establish a lower limit the Earth must be at least as old as any formation on it. This lower limit is at least concordant with the independently derived figure of 4. This involves measurement of three isotopes of lead Pb, Pb, and either Pb or Pb

Once a hominin fossil has been discovered it can be dated by two main ways: 1 by analyzing the volcanic ash around the fossils; 2 by analyzing the other fossils found around the newly discovered hominin bones. In analyzing the volcanic ash around the fossils. If the ash is older than 1. Each volcanic eruption has a unique “fingerprint” and sometimes they scatter ash over a vast area. In analyzing the other fossils found around the newly discovered hominin bones.

Many fossils of the other creatures, such as ancient elephants and rhinos, have been dated before at other locations using the volcanic ash, potassium-argon method described above.

Radiometric dates are consistent with several nonradiometric dating methods. For example: The Hawaiian archipelago was formed by the.

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.

Since, from the eyewitness testimony of God’s Word, the billions of years that such vast amounts of radioactive processes would normally suggest had not taken place, it was clear that the assumption of a constant slow decay process was wrong Wieland It marks a move away from reliance on ‘appearance of age’ and the arguments of creationists like John Woodmoreappe Plaisted , who asserted that radioisotope dates are the result of filtering essentially random numbers through the institutional biases of science.

These young-Earth creationists now argue that radioisotope decay has actually occurred, can be measured accurately, and that it would require billions of years at present rates to account for the current condition of the Earth. The scientific community has been making those very arguments for decades. The RATE team, however, because of their unshakable Biblical faith in a 6, year old Earth, rejects uniformitarianism Humphreys and argues that the rate of decay was greatly accelerated during the first two days of Creation Week and during the year-long Flood of Noah DeYoung This paper examines the evidence RATE cites for believing that decay has been accelerated, the proposed mechanisms for that acceleration, and several difficulties with the theory.

The RATE group identified four separate pieces of evidence for the acceleration of radioisotope decay: 1 helium accumulation in zircon crystals, 2 the existence of polonium halos, 3 isotope discordance, and 4 the presence of 14 C in diamonds Vardiman et al. Zircon crystals contain high quantities of uranium, which produces helium during its decay process. This helium, being a noble gas, should normally be able to escape the crystal more quickly than it would be produced by uranium decay at the present rate; this is borne out by diffusion measurements conducted by RATE.

Yet helium has somehow accumulated in these zircon crystals.

Metrics details. The creationist—evolutionist conflict is perhaps the most significant example of a debate about a well-supported scientific theory not readily accepted by the public. The analysis revealed numerous fallacies including the direct ad hominem —portraying evolutionists as racists, unreliable or gullible—and the indirect ad hominem , where evolutionists are accused of breaking the rules of debate that they themselves have dictated. Poisoning the well fallacy stated that evolutionists would not consider supernatural explanations in any situation due to their pre-existing refusal of theism.

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. All of these theories would be considered compromises [1] to a plain reading of the Genesis creation account. Those who believe in a literal interpretation of Genesis are categorized as Young Earth Creationists.

Age of the Universe

Until the 18th century, this question was principally in the hands of theologians, who based their calculations on biblical chronology. Bishop James Ussher, a 17th-century Irish cleric, for example, calculated that creation occurred in B. There were many other such estimates, but they invariably resulted in an Earth only a few thousand years old. By the late 18th century, some naturalists had begun to look closely at the ancient rocks of the Earth.

They observed that every rock formation, no matter how ancient, appeared to be formed from still older rocks. Comparing these rocks with the products of present erosion, sedimentation, and earth movements, these earliest geologists soon concluded that the time required to form and sculpt the present Earth was immeasurably longer than had previously been thought.

Radiometric dating gives unreliable results ( s)

Antievolutionists often express outrage over alleged incivility from those who oppose their efforts to evade the establishment clause of the First Amendment. But they have no difficulty in dishing out the abuse themselves. Here is a sample from the Invidious Comparisons thread that documents egregious behavior on the part of the religious antievolution advocates. These critics include embryologists, paleontologists, biochemists, molecular biologists, medical doctors, philosophers, and even lawyers.

Unfortunately, the North American science-and-religion establishment has largely turned a deaf ear to these critics, preferring instead to abandon classical theology and embrace metaphysical materialism and moral relativism.

Art for me is many things. In our society, particularly in current times, I believe that art is an affirmation of our humanity; a symbol of perseverance in the face of adversity. It is the light at the end of a tunnel; a much-needed light to counteract the darkness that has engulfed many a homeland. One can control the art but not the reaction to it. Both reactions, in my view, pave the way for progress as one is made to think and question. The materials we choose, the methods of production and the sources of art produced all reflect the interests that commands our attention.

The artist, the subject and the means by which it is rendered are inseparable. When did your interest in art begin? What prompted you to embark on a career in art?
