But what's interesting is that a small fraction of carbon-14 forms, and then this carbon-14 can then also combine with oxygen to form carbon dioxide.
And carbon-14 is constantly doing this decay thing. So over the course of 5,730 years, roughly half of them will have decayed. Well, if you know that all living things have a certain proportion of carbon-14 in their tissue, as kind of part of what makes them up, and then if you were to find some bone-- let's just say find some bone right here that you dig it up on some type of archaeology dig.
We also assume that the sample died with the same ratio of C12/C14 as in the atmosphere, this may not be true if they got the carbon in their diet from geological sources, eg by eating a lot of deep sea fish.
Each chapter will include a few questions designed to test your knowledge of material covered in the chapter and in the Internet-based resources.
By dating rocks of known ages which give highly inflated ages, geologists have shown this method can’t give reliable absolute ages.
Many geologists claim that radiometric “clocks” show rocks to be millions of years old.
It's just a little section of the surface of the Earth. And that carbon-14 that you did have at you're death is going to decay via beta decay-- and we learned about this-- back into nitrogen-14. So it'll decay back into nitrogen-14, and in beta decay you emit an electron and an electron anti-neutrino. But essentially what you have happening here is you have one of the neutrons is turning into a proton and emitting this stuff in the process. So I just said while you're living you have kind of straight-up carbon-14. What it's essentially saying is any given carbon-14 atom has a 50% chance of decaying into nitrogen-14 in 5,730 years.
It will give similar fossils similar ages, even when the fossils are widely separated.
Though they are very tiny, polonium radiohalos have a huge message that cannot be ignored.
They point to a catastrophic origin for granites, consistent with the biblical timeframe for earth history and God’s judgment during the Flood.
After all, textbooks, media, and museums glibly present ages of millions of years as fact.
Yet few people know how radiometric dating works or bother to ask what assumptions drive the conclusions. This figure wasn’t established by radiometric dating of the earth itself. Radiohalos shouldn’t exist, according to conventional wisdom!
