Is carbon dating really reliable
Carbon 14 (C-14) dating was considered to be a tremendous breakthrough in science when Willard Libby devised it in 1946. Read, Journal of Near Eastern Studies, Vol, 29, No. Thus, the meaning of dates by C-14 prior to 1600 B. "If the earth and life on earth are really as ancient as the theory of evolution requires, a great proportion of radiocarbon ages should be infinite.
But subsequent investigations have revealed it to be wholly inadequate for accurate dating of ancient materials. evolution—a Creation-Evolution Encyclopedia, brought to you by Creation Science Facts. This is because, with a half-life of only 5,730 years, initial radiocarbon in a fossil decreases in about ten half-lives to a level too low to be measured."—Robert E.
Of over 4,000 quotations in the books this Encyclopedia is based on, only 164 statements are by creationists. One is that the carbon 14 concentration in the carbon dioxide cycle is constant.
You will have a better understanding of the following statements by scientists if you will also read the web page, . The other is that the cosmic ray flux has been essentially constant—at least on a scale of centuries."—*J. Kulp, "The Carbon 14 Method of Age Determination," in Scientific Monthly, November 1952, p. "Hair from the Chekurovka mammoth that was found in the Lena River delta region of Russia has a radiocarbon age of 26,000 [years] while the radiocarbon age of peat only eighteen inches above the carcass is 5,610.
other isotope pairs cover intermediate time periods between the spans for carbon 14 and uranium.
Some radiometric dating methods depend upon knowing the initial amount of the isotope subject to decay.
C14 is continually being created and decaying, leading to an equilibrium state in the atmosphere.
This date did not fit the preconceived notion that dinosaurs lived millions of years ago. They do this many times, using a different dating method each time. "[d] Deep ocean deposits supposed to contain remains of most primitive life forms are dated within 40,000 years. "[b] Only three of the 15,000 reported ages are listed as `infinite.' "[c] Some samples of coal, oil, and natural gas, all supposedly many millions of years old have radiocarbon ages of less than 50,000 years.CONTENTS: Scientists Speak about Radiocarbon Dating This material is excerpted from the book, DATING OF TIME IN EVOLUTION. Lee, "Radiocarbon: Ages in Error," in Creation Research Society Quarterly, September 1982, pp. But only the scientific community is told that fact.An asterisk ( * ) by a name indicates that person is not known to be a creationist. "Well authenticated dates are known only back as far as about 1600 B. "There are two basic assumptions in the radiocarbon method.
