Geologist Ralph Harvey and historian Mott Greene explain the principles of radiometric dating and its application in determining the age of Earth. As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate. Measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.

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.

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. Various elements are used for dating different time periods; ones with relatively short half-lives like carbon or 14 C are useful for dating once-living objects since they include atmospheric carbon from when they were alive from about ten to fifty thousand years old.

The Age of the Earth
The rock walls were slippery and steep at points, and some people came in their dress shoes straight from the conference that brought them together. Let me see that. A brightly painted sign in the state park explained that million years ago these ancient creatures lived at the bottom of a warm, shallow sea during the Ordovician period. But none of these geologists believed it. As young-earth creationists, they think the earth is about 8, years old, give or take a few thousand years.
Creationist ideas about geology tend to appeal to overly zealous amateurs, but this was a gathering of elites, with an impressive wall of diplomas among them Harvard, U.

Six research scientists with specialized training in Geology, Geophysics, Astrophysics, and Physics met to report on research completed over the past year. They also discussed plans for future activities. An initial approach taken by some of the investigators is to explore models for accelerated rates of decay of radioisotopes during Creation, the Fall, or the Flood.
Several sources of data suggest that significant quantities of radioactive decay have occurred during the history of the earth and cosmos. The conventional age model assumes that this decay has occurred over billions of years at constant rates rather than in concentrated episodes over short periods of time. Some of the RATE researchers believe other explanations that do not require accelerated decay may be the answer, such as the geochemical distribution of elements.
Attention was focused on daughter products of lead, neodymium, strontium, and argon for whole-rock and mineral concentrates. The various linear array plots could be interpreted as “isochrons” from the different dating methods. However, discordant “ages” resulted, even for mineral concentrates from the same rock. Although the discordant isochron “ages” are the normal pattern, the discordance seems to differ in a predictable fashion.
Alpha daughter products give older apparent “ages” than beta daughter products.
Science vs. Fiction
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.

Radiometric dating–the process of determining the age of rocks from the Many Christians accept this and interpret the Genesis account in less scientifically literal ways. My answer is that it is similar to believing in other things of the past.
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.
Radioisotopes and the Age of the Earth

Wanting to hear both sides of the issue, Rob wrote to Answers in Genesis, highlighting when radiometric dating methods are applied to rocks of KNOWN.
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.
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.
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.
