Why carbon dating is flawed
From what i have read, it's not about amount of some radioisotope, but about ratios: For example - when lava comes out of volcano, it contains any amount of uranium-234 (just example), but over time, some of this amount decays into thorium-230. Since you know that half of the uranium-234 decays into thorium-230 in ~80,000 years, you can easily compute the age of lava rock.source: R.
I think that hate really started up when they proved the Shroud of Turin a fake - that was an 'egg on the face' moment for the god botherers. Plants acquire it through photosynthesis, and animals acquire it from consumption of plants and other animals.They do it because they know that if the earth is more than 6,000-10,000 years old, it's absolutely game over for young-earth creationism and biblical literalism in general.They lie, twist and misrepresent the facts about radiometric dating (and wholly ignore the many other corroborating methods) that tell us the actual age of organic materials to preserve their foundational fantasy at all costs.The carbon-14 dating limit lies around 58,000 to 62,000 years.Note that this limit of accuracy (which only applies to radiocarbon dating of all the radiometric dating methods) is still ten times longer than the time span required to comprehensively debunk young earth creationism.
You'd expect to find 100 grams of element A in a sample if it was brand new.
