Cosmic radiation striking the upper atmosphere converts about 21 pounds of nitrogen each year into radiocarbon (carbon-14).Most carbon-14 quickly combines with oxygen to form radioactive carbon dioxide, which then spreads throughout the atmosphere.They concluded that the helium in the rock was 100,000 times more plentiful than it should have been if the rocks were really 1.5 billion years old.They concluded that their findings are consistent with an Earth that is about 6,000 years old.However, before accepting any radiocarbon date, one should know how the technique works, its limitations, and its assumptions.One limitation is that the radiocarbon technique dates only material that was once part of an animal or plant, such as bones, flesh, or wood. To understand the other capabilities and limitations of radiocarbon dating, we must understand how it works and consider the flood. However, roughly one in a trillion carbon atoms weighs 14 atomic units. It is also called radio carbon because it is radio active (but not dangerous).Libby calculated the half-life of carbon-14 as 5568, a figure now known as the Libby half-life.
Carbon dioxide also permeates the oceans, dissolving in the water.When granite rock hardens, it freezes radioactive elements in place.The most common radioactive element in granite is Uranium-238.Outside the range of recorded history, calibration of the 14 clock is not possible.This means the above calculations are only evolution speculation and NOT backed up by real science.
