I've been recapping what I know about Carbon 14 and found something odd. Just to bring us all on the same page.
Carbon 14 starts out as Nitrogen 14 and then decays back into Nitrogen 14.
In terms of decay using modern scientific assumptions, the half life of Carbon 14 is roughly 5,700 years with a total shelf life around 60,000 years through conventional testing mechanisms.
One of the assumptions in Carbon 14 dating is the assumption that the object is uncontaminated. Thus, the dating methodology is unwavering correct. However, I was recently reading how diamonds can have a small amount of Carbon 14 in them.
Now then, I was taught in school that a diamond takes millions of years to form and I believe Scientists still hold to this measure. So we should find no amount of Carbon 14 in a diamond as a result of the diamonds age, but we do.
There are two possibilities for this carbon.
1. The Diamond was contaminated.
2. The Diamond isn't really millions of years old.
So where does this Carbon 14 come from? Scientists are now speculating that it may be possible, but they are not sure, that Uranium (which decays into lead) when it decays can cause the nitrogen in the diamond to convert back to Carbon 14.
Of course, this is just a theory on their part. Meanwhile, young earth proponents use this information to say point to a young earth.
What I find odd however, is how Scientists are now accepting that what was once thought as uncontaminated, can very well be contaminated. And if something can be contaminated, then just how reliable is the dating methods that they tout to be so reliable?
Thoughts?
