::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. [[User:Timppeli|Timppeli]] 11:20, 5 May 2007 (EDT)

==Changing decay rates==
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.

While i remember, i would like to allso point out that the discussion about the "wrongly measured" Carbon rock/oil samples has no conclusion yet. If there is nothing you would like to add to it, i really think those examples should be removed on the basis off what i said on the discussion at the top of the page.

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.
