الرسالة: [QUOTE="ارض الحويلة, post: 365714, member: 18783"] [b]رد على: صورة حقيقية فوتوغرافية للسيد المسيح له المجد وبطرس ويوحنا الحبيب[/b] و بالمرة نتائج الابحاث الكاربونية : Radiocarbon dating is the use of accelerator mass spectrometry (AMS) to measure the amount of C14, a radioactive isotope of carbon. Plants take up carbon dioxide from the atmosphere as part of the process of photosynthesis and incorporate the carbon in the plant tissues. Animals absorb C14 into their tissues by eating plants. When the plant dies, no further C14 is absorbed and the C14 that accumulated in life begins to decay at a known rate. The half life of C14 is calculated at 5,730 years. Measurement of the C14 present in the remains of the plant or animal is a method of determining when the plant or animal died. The procedure is valuable for dating organic material later than 50,000 years before the present time. When first used, the procedure required larger samples of the test material, consequently the custodians of the Shroud of Turin were unwilling to permit the destruction of large portions of the shroud. The advances in the procedure has gradually decreased the amount of sample required and permission was finally obtained to test 12 small samples of the non-image bearing portion of the shroud linen. Linen is made from flax, therefore an assessment could be made on when the linen was manufactured. Samples of the shroud were excised and given to three different radiocarbon dating laboratories in Zurich, Oxford and Arizona. The results of the tests were published in the prestigious scientific journal Nature, 1988, titled "Radiocarbon Dating of the Shroud of Turin." The following results were published on the samples tested. The figures are uncalibrated "before present," i.e. 1950 CE. (P. E. Damon, etal., Radiocarbon Dating of the Shroud of Turin, Nature 337:6208, 16 February 1989, pp 611-615) Sample dates from Arizona: 591 +/- 30 yrs 690 +/- 35 yrs 606 +/- 41 yrs 701 +/- 33 yrs Sample dates from Oxford: 795 +/- 65 yrs 730 +/- 45 yrs 745 +/- 55 yrs Sample dates from Zurich: 733 +/- 61 yrs 722 +/- 56 yrs 635 +/- 57 yrs 639 +/- 45 yrs 679 +/- 51 yrs The linen of the shroud was manufactured, according to these results, sometime between 1260 CE and 1390 CE with the mean value placing the manufacture of the linen in the 14th century! The results were startling and fueled the opinion that the shroud is a forgery manufactured by a clever medieval artist. Are these results conclusive? A final conclusion on the authenticity of the shroud as an artifact of the first century should be based on a totality of the scientific evidence rather than on one procedure alone. That’s just good science, yet the results of this one procedure is totally oppositional to the many other procedures conducted and the use of radiocarbon dating of textiles has been shown to be problematic in the past وللتأكد بنفسكم : [url]http://www.historian.net/shroud.htm[/url] لكن اقرأوا الموضوع حتى اخره .
