hahahaDecay of Earth's Magnetic Field... Dr. Thomas Barnes, Emeritus Professor of Physics at the University of Texas at El Paso, has published the definitive work in this field.4 Scientific observations since 1829 have shown that the earth's magnetic field has been measurably decaying at an exponential rate, demonstrating its half-life to be approximately 1,400 years. In practical application its strength 20,000 years ago would approximate that of a magnetic star. Under those conditions many of the atoms necessary for life processes could not form. These data demonstrate that earth's entire history is young, within a few thousand of years.

You're kidding right?
So? Does that mean it's impossible? LOL....The chance of this assemblage occurring by chance is 1 in 104,478,296

My dad is one of you religious fundy types. He's been waiting for the world to end for the last 35 years. Do you realize that people have always said "These are the last days..."? The Bible is only 2,000 years old. The conflict in Israel and the fact that the Bible talks about it is not proof of God.Originally posted by: DRDEATH

Q]The earth's magnetic field.. Um, hello? It's saying the Earth is only 20,000 years old, a the most. It doesen't take a rocket scientist to know that is false. Radio carbon dating, anyone?
Uhh, are you a scientist? I'ld like to see you find something to dispute that?!?!?!
There are three principal isotopes of carbon which occur naturally - C12, C13 (both stable) and C14 (unstable or radioactive). These isotopes are present in the following amounts C12 - 98.89%, C13 - 1.11% and C14 - 0.00000000010%. Thus, one carbon 14 atom exists in nature for every 1,000,000,000,000 C12 atoms in living material. The radiocarbon method is based on the rate of decay of the radioactive or unstable carbon isotope 14 (14C), which is formed in the upper atmosphere through the effect of cosmic ray neutrons upon nitrogen 14. The reaction is:
14N + n => 14C + p
(Where n is a neutron and p is a proton).
The 14C formed is rapidly oxidised to 14CO2 and enters the earth's plant and animal lifeways through photosynthesis and the food chain. The rapidity of the dispersal of C14 into the atmosphere has been demonstrated by measurements of radioactive carbon produced from thermonuclear bomb testing. 14C also enters the Earth's oceans in an atmospheric exchange and as dissolved carbonate (the entire 14C inventory is termed the carbon exchange reservoir (Aitken, 1990)). Plants and animals which utilise carbon in biological foodchains take up 14C during their lifetimes. They exist in equilibrium with the C14 concentration of the atmosphere, that is, the numbers of C14 atoms and non-radioactive carbon atoms stays approximately the same over time. As soon as a plant or animal dies, they cease the metabolic function of carbon uptake; there is no replenishment of radioactive carbon, only decay. There is a useful diagrammatic representation of this process given here
Libby, Anderson and Arnold (1949) first discovered that this decay occurs at a constant rate. They found that after 5568 years, half the C14 in the original sample will have decayed and after another 5568 years, half of that remaining material will have decayed, and so on (see figure 1 below). The half-life (t 1/2) is the name given to this value which Libby measured at 5568±30 years. This became known as the Libby half-life. After 10 half-lives, there is a very small amount of radioactive carbon present in a sample. At about 50 - 60 000 years, then, the limit of the technique is reached (beyond this time, other radiometric techniques must be used for dating). By measuring the C14 concentration or residual radioactivity of a sample whose age is not known, it is possible to obtain the countrate or number of decay events per gram of Carbon. By comparing this with modern levels of activity (1890 wood corrected for decay to 1950 AD) and using the measured half-life it becomes possible to calculate a date for the death of the sample.
As 14C decays it emits a weak beta particle (b ), or electron, which possesses an average energy of 160keV. The decay can be shown:
14C => 14N + b
Thus, the 14C decays back to 14N. There is a quantitative relationship between the decay of 14C and the production of a beta particle. The decay is constant but spontaneous. That is, the probability of decay for an atom of 14C in a discrete sample is constant, thereby requiring the application of statistical methods for the analysis of counting data.
It follows from this that any material which is composed of carbon may be dated.Herein lies the true advantage of the radiocarbon method, it is able to be uniformly applied throughout the world.
7. Helium Content in Earth's Atmosphere... Physicist Melvin Cook, Nobel Prize medalist found that helium-4 enters our atmosphere from solar wind and radioactive decay of uranium. At present rates our atmosphere would accumulate current helium-4 amounts in less than 10,000 years.12
Well, since the amount of helium in the sun has slowly increased over time, it might be safe to assume the rate of helium accumulating in our atmosphere would also increase over time.Thus using the number 10,000 is a little misleading.
