Huge errors on this page

Firstly, there is an claim that carbon dating had wrongly measured the age of some carbonate rocks, oil etc. Ofc it has, because no one in their right minds and knowing even the basics of carbon dating would try to measure those with this method... Offcourse the result is wrong, it's like saying one was trying to measure weight with measuring tape. The whole concept of giving false measurements as a "proof" that the method dosen't work is ridiculous. Who knows how many measuring errors has happened with measuring tape, but no one is claimin that because person "A" measured the lenght of an tree wrong using a measuring tape, that the measuring tapes arent reliable. Im deleting that whole section. Timppeli 10:47, 5 May 2007 (EDT)

This is factual and informative information. Why censor it? The only reason that "no one in their [sic] right minds ... would try to measure those with this method" is because of significant limitations in carbon dating, which is precisely the point. The math alone does not predict that dating rocks and oil should be as unreliable as the results show.--Aschlafly 11:01, 5 May 2007 (EDT)
So you really think there should be an collection of wrong results when trying to measure weight with measuring tape on the pages descriping the measuring tape? Just to prove that the measuring tape is limited on measuring the lenght? You can't measure things such as rocks, oil etc with carbon dating, from the basic reason that the carbon in it is from petroleum. So no one who knows anything about carbon dating would never even try that. And what do you have to say about the general measuring errors? Do you really think that we should now start to post diffrent wrong reasult people have gotten when they where using a volt meter, measuring tape or scales? That makes no sense at all, as said before, it would be ridiculous and would really like to hear why we should do this. Timppeli 11:20, 5 May 2007 (EDT)

Further corrections i would like to make are allso removing the following sentences: "First, it is impossible to prove scientifically whether the rate of decay of C-14 has remained constant over hundreds or thousands of years. Some scientists have suggested, based on experimental observations, that the laws of physics do change over time." Indeed, for this to happen laws of physics would have needed to change. And to claim that... Well, im speechles, who exactly is claiming that laws of physics have changed so dramatically during these few years and based on what experiments? Firstly, for it to be any help for the young earth creationists, it would have needed to happen during the last 10 000 years. And the laws of physics to change so much that it would change the half time of C-14 atom... Oh boy. I see no place for claim like this on encyclopedia. There is no evidence of anything like this ever happening, and even the idea of this is so strange to modern science that it's once again just absurd to offer that as an excuse for considering carbon dating not to be valid. If this excuse is accepted here, it can be used on every other scientific article here. They all rely on the fact that laws of physics arent changing around. Timppeli 11:33, 5 May 2007 (EDT)

You're "speechless" about a position of Nobel Laureate Paul Dirac and many physicists today??? Maybe what you meant to say is that you've never heard this. OK, most people (including physics majors) don't hear about this. But, please, let's be at least a little open-minded. I've updated the entry.--Aschlafly 12:36, 5 May 2007 (EDT)
First i would like to quote myself: "Well, im speechles, who exactly is claiming that laws of physics have changed so dramatically during these few years and based on what experiments?" You are claiming that Nobel Laurete Paul Dirac claimed so? It has been long known that for example at the time of the big bang, when scientists presume that the laws of physics where allso born, there might have been some changes. But the key here is that for some one to claim that the laws of physics would have changed so much on earth in so reasent history that the halftime of C-14 atom would have been cut down to 1/5th or something around that is just beyond what any scientist would ever claim. It would mean catastroph to other things here. And if claim like that would be accepted here to undermine the Carbon dating, it could, as said earlyer be used to undermine any scientific findings. Timppeli 13:01, 5 May 2007 (EDT)
You've gone from being "speechless" to saying "it has long [been] known." I'm only interested in an open-minded discussion here. If your mind is made up, and you'll treat anything contrary to your opinion with derision, then this is not productive for you or me. We're both better off working on other entries.
If the C-14 decay rate varies proportionately with the age of the universe, and if that age is, say 5,000 years rather than 10 billion years, then obviously the C-14 decay rate could have been many orders of magnitude larger a thousand years ago.--Aschlafly 13:51, 5 May 2007 (EDT)

the 50,000 year mark

The sentence "For this reason, scientists do not generally attempt to carbon date material that is believed to be older than about 50,000-60,000 years old" is factually incorrect. After 50,000 years carbon-14 would have undergone over 8 half-lives and essentially there rate of change has reached a screeching halt. It is the result of both the small amout of carbon-14 and the length of the half-life that prevent dating back to 50,000 years. Sterile 13:59, 5 May 2007 (EDT) This was addressed in the time I wrote the comment.

Changing decay rates

For decay rates to change, you'd have to drastically change some of the laws of physics and/or the rest mass of several types of subatomic particles, if this were to happen, chances are entire solar systems will disintegrate and some chemical compounds would not be stable anymore, it is likely something as complicated as carbon based live would die: meaning ALL carbon based life in the universe.

Dirac's ideas about gravitation are highly speculative, highly criticized and deal only with small changes over billions of years, so minute they wouldn't even be detectable over the course of 60,000 years.

Speculation about changing laws of physics are a desperate attempt at creating confusion among those who have accepted evolution to be true. They were inserted here by the same person who argued that there was no way to figure out the CO2 concentrations in the atmosphere over hundreds of thousands of years (there are, and carbon dating is limited to 60,000 years anyway) in an attempt to discredit carbon dating.
