Carbon 14 dating 1
Like we had for nitrogen, we had seven protons. So it's not really an element. It is a subatomic particle. But you have these neutrons form. And every now and then-- and let's just be clear-- this isn't like a typical reaction. But every now and then one of those neutrons will bump into one of the nitrogen's in just the right way so that it bumps off one of the protons in the nitrogen and essentially replaces that proton with itself.
So let me make it clear. So it bumps off one of the protons. So instead of seven protons we now have six protons. But this number 14 doesn't go down to 13 because it replaces it with itself. So this still stays at And now since it only has six protons, this is no longer nitrogen, by definition. This is now carbon. And that proton that was bumped off just kind of gets emitted.
So then let me just do that in another color. And a proton that's just flying around, you could call that hydrogen 1. And it can gain an electron some ways. If it doesn't gain an electron, it's just a hydrogen ion, a positive ion, either way, or a hydrogen nucleus. But this process-- and once again, it's not a typical process, but it happens every now and then-- this is how carbon forms.
So this right here is carbon You can essentially view it as a nitrogen where one of the protons is replaced with a neutron. And what's interesting about this is this is constantly being formed in our atmosphere, not in huge quantities, but in reasonable quantities.
So let me write this down. And let me be very clear. Let's look at the periodic table over here. So carbon by definition has six protons, but the typical isotope, the most common isotope of carbon is carbon So carbon is the most common. So most of the carbon in your body is carbon But what's interesting is that a small fraction of carbon forms, and then this carbon can then also combine with oxygen to form carbon dioxide.
And then that carbon dioxide gets absorbed into the rest of the atmosphere, into our oceans. It can be fixed by plants. When people talk about carbon fixation, they're really talking about using mainly light energy from the sun to take gaseous carbon and turn it into actual kind of organic tissue. And so this carbon, it's constantly being formed.
It makes its way into oceans-- it's already in the air, but it completely mixes through the whole atmosphere-- and the air. And then it makes its way into plants. And plants are really just made out of that fixed carbon, that carbon that was taken in gaseous form and put into, I guess you could say, into kind of a solid form, put it into a living form.
That's what wood pretty much is. It gets put into plants, and then it gets put into the things that eat the plants. So that could be us.

Now why is this even interesting? I've just explained a mechanism where some of our body, even though carbon is the most common isotope, some of our body, while we're living, gets made up of this carbon thing. Well, the interesting thing is the only time you can take in this carbon is while you're alive, while you're eating new things. Because as soon as you die and you get buried under the ground, there's no way for the carbon to become part of your tissue anymore because you're not eating anything with new carbon And what's interesting here is once you die, you're not going to get any new carbon And that carbon that you did have at you're death is going to decay via beta decay-- and we learned about this-- back into nitrogen So kind of this process reverses.
So it'll decay back into nitrogen, and in beta decay you emit an electron and an electron anti-neutrino. I won't go into the details of that. 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.
Now why is this interesting? So I just said while you're living you have kind of straight-up carbon And carbon is constantly doing this decay thing.
Other pieces include carbon in diamonds, other soft tissue found in dinosaur fossils, and evidence that conventional dating methods are inaccurate. Carbon in diamonds Diamonds supposedly formed even further back in the past than dinosaurs —over a billion years ago.
There is even less reason to expect to find carbon in them, but it has been found. This is so contrary to conventional theory that the discovery met with disbelief at first. Lava that obviously flowed around a piece of wood, since the hardened lava has taken the shape of the wood, has been dated as having solidified millions of years before the wood existed.
Experiments are replicated in the belief that increasing the number of results supporting a hypothesis increases the evidence for the hypothesis. In a similar manner, the more evidence of young ages for dinosaur fossils, the more compelling the evidence in total becomes. Could the dinosaur ages now be said to be precisely what the carbon dating results indicated?
Even this is too old for many creationists, who would expect them to be less than 6 to 10 thousand years old. Several factors may possibly account for this seeming discrepancy. According to this theory, the proportion of carbon would have been higher due to the removal of much normal carbon.

The increased humidity before the flood would have reduced the formation of carbon in the atmosphere, while the drier air after the flood would have allowed more carbon formation. This could make younger fossils yield dates greater than their actual age. One interesting observation is that rapidly-growing body parts, such as hair, would absorb carbon from most recent concentrations, while slower-growing body parts, such as bone or muscle, might contain concentrations of carbon based on levels of carbon existing at earlier times in the environment of the animal.
Therefore, evidence of differing carbon concentrations i. We now will look to see if there is just such evidence. A frozen musk ox found at Fairbanks Creek, Alaska, had scalp muscle tissue 24, years old and hair 17, years old according to carbon dating.
At least three other frozen animals, two mammoths and a mastodon, have been found with parts of their bodies with carbon ages far different from other parts or from surrounding plant life that perished with or shortly after the animals. Other dates are thrown into question. This implies there may be less certainty about the time frame during which species supposedly evolved. One point that is worth noticing is that these dinosaur ages are all much younger than the conventional ones.
This implies there was less time for evolution to occur. Even with the accepted millions and millions of years for evolution to supposedly have brought mammals into existence from their precursors, evolution still has many problems.Carbon- 14 Dating Explained in Detail
Shortening the time available just makes evolution even more unlikely. Co-occurrence of men and dinosaurs. Such an association would dispel an Earth with vast antiquity. The entire history of creation, including the day of rest, could be accommodated in the seven biblical days of the Genesis myth. Evolution would be vanquished. Stanley, Johns Hopkins University: There is an infinite variety of ways in which, sincethe general concept of evolution might have been demolished.
The unequivocal discovery of a fossil population of horses in Precambrian rocks would disprove evolution. More generally, any topsy-turvy sequence of fossils would force us to rethink our theory, yet not a single one has come to light. As Darwin recognized, a single geographic inconsistency would have nearly the same power of destruction.

Do we look at the evidence and let it speak, or do we deny the evidence because of our biases? This is the choice we face when confronted with evidence such as presented in this article. Theories built on evidence is science; evidence built on theories evidence accepted because of confirmation of existing theories or evidence rejected because it contradicts existing theories is dogma built on bias.

Compare this with http: Notice the titles of 4 and 6 correspond in both lists, which in the opinion of some, hints strongly that the list with number 5 present was an original list.
