It reduces the incidence of -charged particle- cosmic radiation over most of the planet and funnels them to the polar regions where they generate auroras. The magnetic fields also cause them to loose energy as they spiral along the field lines (I know, oversimplified) in the Brehmsstrahlung process, so the ones that get through are weaker. It does nothing to stop gamma rays and neutrons from pounding the top of the atmosphere, and C-14 is still produced that way and by charged particle collisions in the polar regions.

Ah! But remember, with God...ALL things are possible. Praise Allah!!

Actually, the only truthful things Brian said were as follows:


I just can't believe he's a Canuuck , I thought they were all sensible......

I believe that he is a Yank, it is tgamble who is a Canuck. That being said, there are a few creationists up here (but much more rare than south of the border).

Nah, Just the newfies.

Wrong. Tree-ring chronologies provide a direct record of atmospheric 14C concentration that extends back to about 10,000BCE, and shows that the concentration has not changed significantly during that time (e.g. Becker, 1993; Kromer and Becker, 1993). The varved sediment chronology of Kitagawa and van der Plicht (1998) extends this record of 14C back to 45,000 yr BP. So, again, there is a direct record of atmospheric 14C concentration provided by these data, jabbing a thumb in the eye of such speculation.

On the contrary, YECs seem to agree that the geomagnetic field was much, much stronger before the flood than it is now (how much stronger depending on the supposed GMF decay half-life)! Thus, 14C production rates by cosmic rays before the flood would have been much lower than the present production rates, due to the greater geomagnetic shielding effect. See also the section on production rates on this page: <a href="http://www.geocities.com/earthhistory/tcn.htm" target="_blank">Cosmogenic Exposure Dating and the Age of the Earth</a>

And again, the speculation is rendered moot because the evolution of the geomagnetic field strength over time is recorded in both sedimentary and igneous proxies -- such as the alignment of plagioclase crystals in basalt. Analyses of these proxy records show the average strength of the geomagnetic field has remained relatively constant from the Archean to the recent, within about a factor of 2. See, for example:

Just some interesting and fun comparisons of time lines when someone claims that the entire planet was covered with water. Strange how these other cultures failed to notice or make historical records of this difficult to ignore event. I wonder how Brian would account for that?

Don't bet on it. This guy isn't the one who'll find it, but among those who might no one is prepared to put money on it one way or the other.

Fabrications of the evilutionists to descredit the bible. Just more evidence of Christian persecution. blah blah blah.

tgamble

patrick, mind if I use that material in replies to him? Giving you full credit of coures.

Through you being an evil atheist evilutionist and all, it might backfire.

Thanks.
