When their dating methods say that something lived 30,000 years ago, they sound certain.
And on the basis of these methods, many scientists announce that the Bible's record of history is not accurate.
Since carbon comes from the air, does the amount of carbon-14 in the air remain constant?
Much of the carbon in the air is C-12, but a small amount of it is C-14.
But the cosmic ray bombardment changes moment by moment, day by day and week by week.
Such activity as sun spots or solar storms will affect the cosmic radiation.
One assumes that there is enough sand in the timer so that it takes three minutes for it to move from the top of the glass to the bottom of the glass.
When cosmic rays enter the atmosphere, they cause "scatter radiation," which consists of little particles called neutrons.
A moving neutron is a high-energy particle which performs an interesting task.
Let's consider the Flood and use what is called the "canopy theory." There is some evidence for a canopy surrounding the Earth before the Flood.
The canopy would probably not stop all the cosmic rays themselves, but a good deal of the scatter radiation would be reduced. Thus, there would be a few neutrons and fewer C-14 atoms formed.
