All living things are made up of about 25% carbon. The carbon atom is unique because it can bind to other carbon atoms to form long chains and rings and these in turn serve as the backbone of the complex molecules that make life possible. The nucleus of a typical carbon atom has 6 protons and 6 neutrons. But about one carbon atom out of every 100 has one extra neutron. This has very little effect on the properties of the carbon, other than making it slightly heavier. Chemically, it acts just like any other carbon atom. It is called Carbon-13. And there is an even rarer type of carbon. It is formed high in the atmosphere when cosmic rays strike atoms of nitrogen converting them into Carbon -14. Carbon-14 is also chemically identical to regular carbon. But the nucleus of carbon-14 is unstable. After some amount of time, which could range from a few days to many thousands of years, carbon-14 decays back into nitrogen. But since carbon-14 is formed at a steady rate, there is a constant level of it in the environment. Out of every trillion carbon atoms in your body, only one dozen of them are carbon-14. As long as an organism is alive and eating, it maintains a constant ratio of carbon-14 to regular carbon. But once an organism dies, the amount of carbon-14 in its body begins to decrease. After 5000 years about half of the original number of carbon-14 atoms will have decayed. Using this fact, scientists can tell how long ago an organism died. • http://www.cassiopeiaproject.com .

Ironically, she wants the Uranium that proved this planet is over four billion years old (Uranium-lead dating). Arizona state Senator Sylvia Allen (R) voices support for opening up uranium mining in the state. Sen. Allen responds to statements by environmentalists by assuring them that the "Earth is 6,000 years old ..." Twice. This is a common creationist claim: a 6,000 year old Earth contradicts science and goes by tracing the descendants of Adam and Even from the Christian Bible. After first making her video debut on ArizonaGuardian.com, Arizona state Senator Sylvia Allen hits the bigtime: MSNBC's "Countdown" with Keith Olbermann and the big winner of "Worst Persons." --- RADIOMETRIC DATING (often called radioactive dating) is a technique used to date materials, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates. It is the principal source of information about the absolute age of rocks and other geological features, including the age of the Earth itself, and can be used to date a wide range of natural and man-made materials. Together with stratigraphic principles, radiometric dating methods are used in geochronology to establish the geological time scale. Among the best-known techniques are radiocarbon dating, potassium-argon dating and uranium-lead dating. By allowing the establishment of geological timescales, it provides a significant source of information about the ages of fossils and the deduced rates of evolutionary change. Radiometric dating is also used to date archaeological materials, including ancient artifacts.

Creation Science 101: Carbon Dating
 
05:42
Continuing my response to Desertfools challenge, which he has yet to respond back to. Carbon-14 dating is often cited by evolutionists as a means of disproving Young Earth Theory because it supposedly demonstrates the Earth to be older than 6,000-10,000 years. In response to this many creationists like myself point out the many, many assumptions and inconsistencies with radiometric dating. I wont be dong that here. It turn out that if we allow the evolutionists to have their way and we just say Okay, Carbon-14 (radiocarbon) dating is reasonably accurate. we can use it to disprove Old Earth Theory, and with it naturalistic gradualism and everything that goes with it such as evolution and the big bang. As is so often the case with evolutionary science, what they claim as support for their side of the debate is actually a two-edged sword that, on one hand, appears to support them, but on the other hand, also disproves them when you take the time to dig deeper into the evidence. I leave it to you to decide which side has the stronger argument regarding radiocarbon dating. I'm still waitng Desertphile, Thunderf00t, Extant Dodo, CDK007, coctopus, and the rest of the evoltuionists crowd. I dare you to engage me on the science I present here. This video is captioned.

Italian scientists says Holy Shroud dating inaccurate
 
02:17
In 1988, carbon-14 tests concluded that the Shroud of Turin, the piece of cloth widely regarded by history as having wrapped the body of Jesus after his death, was a fake fabricated around the year 1260. Italian scientists, however, are now debunking that this idea, claiming that the dating test did not work and that the laboratory hid errors. Vatican insider Marco Tossati has repeated vital calculations and says that the original test was not valid. Marco Tossati Author, Investigation of the Holy Shroud The labs didnt publish very many details. And it was evident that the ones they did publish had an error. It sounds like a small mistake, but its huge, because it means that the margin of trust of the entire test is well below the minimum that the laboratories stated. The original carbon 14 test was performed in three parts by three separate laboratories that each tested on an eight centimeter piece cut from the shroud. The discrepancy came when all three laboratories reported different results. Marco Tossati Author, Investigation of the Holy Shroud Were not talking about religion. Were talking about numbers that dont leave room for discussion. The numbers are what they are. The test was not trustworthy, and they should explain why this is the case. They ended up with discrepancies that render the test invalid. Scientists dont consider carbon-14 dating a perfect science and when used its usually tested against other methods. But it was a small detail that gave way to a discrepancy that, evidently, all three labs knew about. Marco Tossati Author, Investigation of the Holy Shroud These same laboratories have had faulty results in the past. They said the tablecloth of one of the scientists mother-in-laws was 300 years old. Or that the bones of a mummy from Ibis dated from 1,500 years before Christ, and the cloth on her body from 200 years after Christ. Until now, the carbon-14 test was the only method that rendered the Holy Shroud a fabrication. All other tests pointed the other way, suggesting the shroud was the original cloth that wrapped the body of Christ. Thats why Marco Tossati and others are calling for new tests to determine the truth behind this historical piece of cloth that remains timeless.

Creation Evidence
 
05:09
Oh, the Institute for Creation Research. They're so funny. Check out this ringer: http://www.icr.org/carbon-14/ Reading these articles is sort of like a brain teaser. Just pretend it's a game called "Find the Logical Fallacy." Diamonds are part of kimberlite pipes, which are mantle plumes. There are many examples of these from all points in geologic history. Age constraints on diamonds are extremely good from all major dating systems. C-14, however, is not a major dating system for igneous rocks. Creationists often will pick on C-14 because it has problems, such as a low temperature Curie point (at which it will reset), often becomes contaminated, and depends on measurements of current atmospheric carbon. For igneous rocks younger than 1 billion years, the most common dating system is Potassium-Argon.

The earth is only 6000 years old??
 
02:54
In this video I will be discussing the statement that the earth is on 6000 years old. This statement is obviously untrue all we need to do is look to science for the answer. Science through the technique of radiometric dating have discovered that the earth is in fact around 4.5 billion years old. Creationists will often state that current techniques such as carbon dating etc are incorrect and flawed, and as usual they make these claims with absolutely no evidence that their statement is even remotely true. They may point to a single contaminated subject and claim that this proves it is unreliable. This however is false, let me try to explain how radiometric dating works. Rock minerals naturally contain certain elements and not others. By the process of radioactive decay of radioactive isotopes occurring in a rock, exotic elements can be introduced over time. By measuring the concentration of the stable end product of the decay, coupled with knowledge of the half life and initial concentration of the decaying element, the age of the rock can be calculated. Typical radioactive end products are argon from potassium-40 and lead from uranium and thorium decay. If the rock becomes molten, as happens in Earth's mantle, such nonradioactive end products typically escape or are redistributed. Thus the age of the oldest terrestrial rock gives a minimum for the age of Earth assuming that a rock cannot have been in existence for longer than Earth itself.. So radiometric dating doesnt simply test one elements but many. Since we can test many different substances in one piece of rock this also allows us to compare the results, if 20 different substances are analysed and each one gives the same age we can be fairly certain that the age given is accurate. This is why radiometric dating is used, it is not simply one test but many different test which all provide the same answer. Radiometric dating is based on very sound scientific princiapals and had been fine tuned for the last 50 years to ensure that samples are not contaminated and that results are accurate. If you want to know more about radiometric dating then check out the wikipedia entry, I would always recommend wikipedia because it can and does have some rubbish on it, but in this case the facts are all there. So please rate comment and thanks for watching.

Are Rocks Accurate for Dating?
 
02:04
1 Corinthians 2:7 But we speak the wisdom of God in a mystery, the hidden wisdom which God ordained before the ages for our glory One of the common methods of finding the age of rocks, and ultimately the age of the Earth, measures the decay of radioactive uranium into lead the more lead, the older the rock. The method, however, makes some very big assumptions. First, scientists assume there was no lead in the rock when it first formed, but this is unprovable. Then, they assume that rocks are like locked vaults and that no uranium, lead, or the in between decay elements can ever enter or leave the rock. The fact is, numerous scientific studies show all these assumptions are wrong. Studies have shown that commonly dated rock material can have lead in it as it crystallizes. Other studies have shown that lead, uranium and the other elements important for dating can be removed from the rock by simple weathering or other conditions. In other words, while evolutionary scientists compare rocks to locked vaults, we are learning they are more like sponges. This explains why evolutionary dating methods have found, for example, one part of a rock to be 30 times older than another part of the same rock. The next time you hear someone say that certain rocks or the fossils in them are millions or billions of years old, just remember that rocks are not like vaults. They are more like sponges that gain or lose elements, making accurate dating impossible. There is no good scientific evidence that the Earth is any older than the few thousand years indicated by the Bible. Prayer: I thank You, Lord, that I can trust You as the Rock of Ages. Amen.

Chemistry Music Video 10: One Half Life To Live

This song explains how the decay of a radioisotope has a half-life and how to use that half-life to solve decay problems. All music and lyrics copyright 2007 by Mark Rosengarten. All rights reserved. Lyrics: A chunk of rock just sits there, underneath the ground Waiting many eons until it can be found Its aglow not just with hope, but radioactivity Its nuclei decaying with regularity! An ancient scroll lies unsuspected on a desert shore Dunes surround its resting place, will it lie evermore? If its found by humans, it will blow their mind Thanks to carbon-fourteen, its timeless age theyll find! Half-life is defined, in each and every way As the time it takes for half the nuclei to decay From parent nuclei into daughter it will give And who can know when there is only one half-life to live? The half-life I-131 is listed at 8 days So if you have ten grams right now, 5 grams will decay If you go another eight, youll be left with two point five Keep cutting it in half for as long as youre alive! Hop into your time machine to eight days ago Double the ten grams you had, twenty grams will glow Go back a further half-life, back to sixteen days You would have had forty grams of iodine that decays! Half-life is defined, in each and every way As the time it takes for half the nuclei to decay From parent nuclei into daughter it will give And who can know when there is only one half-life to live? Flip a coin into the air, watch it as it sails Will it come up heads, or will it come up tails? Its just like a nucleus, each isotopes chance is half To decay in any given half-life, does that make you laugh? So halve the grams of isotope for each half-life thats gone by Or double grams for each half-life if in the past it lies Find how old the rock is, or how ancient is the scroll Once you find the answer, the story can be told! Half-life is defined, in each and every way As the time it takes for half the nuclei to decay From parent nuclei into daughter it will give And we can never know when theres one half-life to live! Hey, guys! Schrödingers Cat is alive!

2012 end of the world -  Stonehenge Mayan Calendar link : UFO Sightings  included.
 
07:35
Definitive Doomsday link to Mayan prophecy found during expedition to date some of the Stonehenge carvings using Carbon Dating. Some visible to the naked eye and some very worn, requiring laser scanning to enhance their images. The Mayan calander, the Sumerians, and Stonehenge, among others, all predict the End of Days, or Doomsday on December 21, 2021. They all date back to a specific point in time. Stonehenge has been dated back to having been built 3100 BC, The Mayan Calander has been dated back to 3100 BC, and the Sumerian written language has been dated as first appearing in the year 3100 BC. Now all three support the end on December 21, 2012 December 21, 2012 represents the date of the end of the original use of Stonehenge as a timing device. The exact date of the last Winter solstice that will reflect light into stonehenge. One more piece to the doomsday puzzle has been presented with scientific based evidence. Whether the world is doomed to come to an end or not, I do not have the answer, but one thing is for certain, something is going to happen. The Stonehenge connection to the Maya Civilization and Sumerians is too strong to ignore. Stonehenge is a sophisticated astronomical observatory, which can predict with pinpoint accuracy, the alignments of the stars as well as solar and lunar eclipses. The recent archeological findings of Sumerian numerals carved into the stones and Radio Carbon dated to 3100 BC are a definitive link to both the Sumerians as well as the Mayans. Maya Civilization was involved in research that predicted a return date of Nibiru passing Earth coinciding with the Winter Solstice of 2012; specifically at 11.11 UT, 21st December 21, 2012 The term "Nibiru" comes from the Sumerian cuneiform tablets and writings dating 5,000 years old. The term Nibiru means "Planet of the crossing", and it's cuneiform sign was often a cross, or various winged disc. Some authors believe that the observations of ancient astronomers provide proof that Nibiru is an actual planet or brown dwarf in our solar system. These claims are for the most part dismissed as fringe science or pseudoscience by the mainstream scientific communities of archaeology and astronomy. According to theories of Sumerian cosmology, Nibiru was the twelfth member in the solar system family of planets (which includes 10 planets, the Sun, and the Moon). It was the home of a technologically advanced human-like alien race, the Anunnaki of Sumerian myth who survived and later came to Earth, subsequently genetically engineered our species. Their travelling to earth was the result of their failing atmosphere.
