Some scientists argue that the magnetic field of the earth has declined over time.

c) Atmospheric carbon forms just 0.0005% of the current carbon reservoir—99.66% of the earth's carbon exists in limestone, 0.31% in oil and gas, and 0.02% in coal.

This assumption is backed by numerous scientific studies and is relatively sound.

However, conditions may have been different in the past and could have influenced the rate of decay or formation of radioactive elements.

Carbon-14 comes from nitrogen and is independent of the carbon-12 reservoir.

If even a small percentage of the limestone deposits were still in the form of living marine organisms at the time of the Flood, then the small amount of carbon-14 would have mixed with a much larger carbon-12 reservoir, thus resulting in a drastically reduced ratio.

Many examples from literature show that the zero-reset assumption is not always valid.

d) Even if the rate of decay is constant, without knowledge of the exact ratio of carbon-12 to carbon-14in the initial sample, the dating technique is subject to question.

It is assumed that we are dealing with a closed system—no loss of either parent or daughter elements has occurred since the study material formed.

No scientist can guarantee that any sample can be considered a closed system unless it was isolated from its environment when it was formed.

Elements can be transported into a sample or leach out of a sample.

Scientists will reject theories about the age of the earth that do not conform to the norm.

Evolutionists assume that the rate of cosmic bombardment of the atmosphere has always remained constant and that the rate of decay has remained constant.



(B) In order to make this determination, the contracting officer may request the offeror to submit prices paid for the same or similar commercial items under comparable terms and conditions by both Government and commercial customers; and (C) If the contracting officer determines that the information described in paragraph (c)(3)(ii)(B) of this section is not sufficient to determine the reasonableness of price, other relevant information regarding the basis for price or cost, including information on labor costs, material costs and overhead rates may be requested.… continue reading »
