carbon dating, 利用其半衰期 就是HOAX, 我们都说过无数次. 我们用更先进的, 精准的. 全世界只有我们有这样的技术.

我们不想说太多的世界历史, 中国历史. 中国历史来说, 夏商周, 夏, 或夏商是否存在都不好说.  情况极度混乱. 学校里学的都是靠猜, 靠砖家自行决定, 臆测. 

AI 骗你没商量. 关键AI它自己也是受害者. 

 

The half-life of carbon-14 is 5,730 years. [1]
Key Facts About Carbon-14 Half-Life
  • Definition: A half-life is the time it takes for half of a radioactive isotope's atoms to decay. For carbon-14, 50% of the original amount decays into nitrogen-14 every 5,730 years. [1, 2, 3]

  • Step-by-Step Decay:
    • Start (0 years): 100% of carbon-14 remains.
    • After 1 half-life (5,730 years): 50% remains.
    • After 2 half-lives (11,460 years): 25% remains.
    • After 3 half-lives (17,190 years): 12.5% remains. [1, 2, 3]

  • Radiocarbon Dating Limit: Because the amount of carbon-14 becomes too small to measure accurately after about 10 half-lives, Carbon-14 Dating Explained on Khan Academy works for organic materials up to roughly 50,000 to 60,000 years old. [1, 2, 3]
