放射性同位素衰变速率的波动影响碳测年技术?

2014 - 07 - 06 - t16:23:23z

2010年,普渡大学发表的一份研究报告[1]指出,他们的研究人员已经发现轻微的放射性同位素衰变速率的波动“同步旋转的太阳核心。”The article also stated:

The team has not yet examined isotopes used in medical radiation treatments or for dating of ancient artifacts.

Has there been any further research on this, and has it been found to affect carbon dating techniques or other archeological dating methods? Are the fluctuations large enough to call into question currently accepted geological dates?

首先,所谓的被报道是周期性变化。所以考古约会的净效应将是零,即使这些变化的存在。 其次,这些传说中的变化非常可疑。科学家们从“疯子综合症”也不能幸免。如果有什么区别的话,科学家更容易受到这种比普通公众。有一些疯子潜伏在每一个优秀的科学家。他们的工作,他们的存在,在推动人类知识的界限。很好的倾听他们内心的疯子科学家但保持内部,直到他们非常相信自己内心的疯子发现一些新的东西。不太好科学家经常暴露自己内心的疯子给全世界看。 这意味着当你读到一些特别声称你应该非常可疑,至少在第一位。他们可能会发现一些东西,再说,他们可能只是暴露自己。 在这种情况下,我怀疑后者。 What I suggest in the case of extraordinary claims: Go to a site such as scholar.google.com and search for the journal article in question. Scholar gives a citation count (oftentimes inflated, but that's a different story). Click on it and you'll get a new page that lists the articles that cited the article in question. In this case, you'll see that there have been a paltry 25 citations in the 8 years since the article was published. That alone is very noteworthy. This article that you think is significant is anything but.

If you dig deeper, you'll see that almost all of those 25 citations are self-citations, subsequent articles by one or more of the original authors who have cited their own work. That makes this article even more suspicious. If you filter out the self-citations, you'll see that the original list of 25 citations dwindles down to two or three, and most of those say "There's nothing to see here. Move along, move along."

我从来没听说过这个类型的变化,但也有< a href = " http://en.wikipedia.org/wiki/Radiocarbon_dating # Dating_considerations”rel = " nofollow noreferrer " >其他变量被科学家们进行放射性碳年代测定法< / >,如: < ul > <李> 碳14 /技术比例——这导致< a href = " http://en.wikipedia.org/wiki/Radiocarbon_dating #校准”rel = " nofollow noreferrer " >校准日期的< / > < /李> <李> 同位素分馏,生物体略少c13和碳14比相比,大气中;这一比率在这一年中我的变化与不同的动物吃食物的同位素比值在不同季节 < /李> < / ul > 和许多其他人。所有这些影响都考虑到,即使这个发现不仅仅是一个测量工件(我倾向于相信大卫Hammen < a href = " //www.hoelymoley.com/a/2315/101 " > < / >,它是),它不会影响到约会。
