Why Carbon Dating Might Be in Danger

Radiocarbon dating is a method that provides objective age estimates for carbon-based materials that originated from living organisms. The impact of the radiocarbon dating technique on modern man has made it one of the most significant discoveries of the 20th century. Archaeology and other human sciences use radiocarbon dating to prove or disprove theories. Over the years, carbon 14 dating has also found applications in geology, hydrology, geophysics, atmospheric science, oceanography, paleoclimatology and even biomedicine. Radiocarbon, or carbon 14, is an isotope of the element carbon that is unstable and weakly radioactive. The stable isotopes are carbon 12 and carbon Carbon 14 is continually being formed in the upper atmosphere by the effect of cosmic ray neutrons on nitrogen 14 atoms. Carbon Dating: (How) Does It Work?

Factor 7: Partial pressure. Factor 8: Magnetic field. Factor 9: Fossil fuels current and future. Bya dead plant could be almost identical to the Dead Sea scrolls, which are more than 2, years old. Factor Disequilibrium. His reasoning was based on a belief in deep time and evolution.

When scientists attempt to stretch the results of carbon dating back many thousands of years, do they inadvertently violate any of the assumptions discussed above? How can we know without being there to measure the various factors to see if the assumptions hold true? Many results continued to come back with varying dates for various artifacts of known ages i. The results of the study confirm that something is amiss:[xix]. The British Science and Engineering Research Council which funded the installation of the C14 apparatus at Oxford ran a series of tests in with 38 laboratories involved worldwide.

As a consequence, the council has insisted this year on new quality-control measures, by which checks are made with standard reference materials of known age. Of the mass spectrometry technique used at Oxford, Dr.

Fairbanks of the observatory staff points out that since the C14 dating depends on the ever-variable quantity of C14 in the atmosphere produced by cosmic rays, any alteration of that production either by nature, or by the solar system, or by man-made interference such as thermo-nuclear bombs must cause a collapse of the whole hypothesis.

He quotes the significant underestimation of the age of ancient objects and states that in a large number of tests C14 failed consistently, the samples being far older than the C14 findings showed.

Do we know about all the forest fires and volcanic eruptions that have occurred in the distant past? Atomic activity? Solar flares and cycles? A final factor to consider when it comes to carbon dating is the worldwide Flood described in Genesis 69, plus the recent Ice Age that followed right after the Flood.

Creation scientists have investigated this, and believe the Flood explains why most dinosaur bones typically cluster between 17, to 49, radiocarbon years. Baumgardner, Andrew Snelling, D.

Law, C. London: British Museum Press,p. It is likely that the world following the Flood would have been much wetter with fewer contrasting seasons until after the Ice Age, which could explain the apparent date of the tree based on counting its rings. Carbon dating today assumes that the system has been in equilibrium for many thousands of years. Further, tree ring patterns are not unique like fingerprints. Batten Batten, Don. Consequently, the calibration is a circular process and the tree ring chronology extension is also a circular process that is dependent on assumptions about the carbon dating system see: B.

  1. I consider, that the theme is rather interesting. I suggest all to take part in discussion more actively.

  2. I can not participate now in discussion - it is very occupied. But I will be released - I will necessarily write that I think.

  3. I consider, that you are not right. I am assured. I can defend the position. Write to me in PM, we will talk.
