By GriffonDecember 29, in Physics. I've been poking about on the internet again as you do and found a whole load of stuff by creationists about the problems with carbon 14 radiometric dating. Specifically they report with some glee that coal has been found to contain measurable amounts of carbon14 which it should not of course because it is about million years old and dates from the carboniferous period. C14 has a half life of years and is only good to date objects to 50, years or so. Although I can find any number of references to this seemingly vital finding on the creationist sites, I can find almost no attempt to refute or explain this anomaly on serious science sites. This looks like a serious oversight to me. There seem to be some unsubstantiated references to the possibility of neutrons generated by uranium decay resulting in an anomalously high presence of C Problems with isotope dating small apparent non-zero values are less than measurement error.
Petrology Tulane University Prof. Stephen A. Nelson Radiometric Dating Prior to the best and most accepted age of the Earth was that proposed by Lord Kelvin based on the amount of time necessary for the Earth to cool to its present temperature from a completely liquid state. Although we problems with isotope dating recognize lots of problems with that calculation, the age of 25 my was accepted by most physicists, but considered too short by most geologists.

More about problems with isotope dating:
The work of geologists is to tell the true story of Earth's history—more precisely, a story of Earth's history that is ever truer. A hundred years ago, we had little idea of the story's length—we had no good yardstick for time. Today, with the help of isotopic dating methods, we can determine the ages of rocks nearly as well as we map the rocks themselves. For that, we can thank radioactivity, discovered problems with isotope dating the turn of the last century. A hundred years ago, our ideas about the ages of rocks and the age of the Earth were vague. But obviously, rocks are very old things.
The subject needs wider exposure. Credit Joan Rivers for taking a strong stand. Other well known Jewish entertainers,etc could be solicited to add their voices. I spent several years as the lay leader for a military synagogue where a local group of the messianic Jews made numerous attempts to infiltrate our synagogue.
So for the most part I was able to keep them out of our synagogue by approaching them, and confronting them with the problems with isotope dating that I knew who they were and what they wanted. IF they chose to stay for service -- they were to make no attempts at discussion of their belief. Or, they would be escorted out. So may I suggest strongly based on my former association, and knowledge of how they work -- that every effort be made to advertise in major and local news papers across the nation -- frequently -- some of the excellent books that can be obtained that refute their claims.
Still we share the same thoughts on this в I should just have you be the official spokesperson for this thread, Marg. It would keep my blood pressure down. It amazes me that instead of reading the discussion or the article for that matteryou just want to shout at the air and rant about things that nobody here has said. You are just screaming at the airв because for some reason you want to be angry and yell in front of an audience. I just wanted to applaud you for this piece. Many people think it has to be one extreme or the other, but I think you did a fantastic job praising all the different body types of women.
