Carbon dating is a way of determining the age of certain archeological artifacts of a biological origin up to about 50, years old. It is used in dating things such as bone, cloth, wood and plant fibers that were created in . What is Carbon Dating? Carbon is one of the chemical elements. Along with hydrogen, nitrogen, oxygen, phosphorus, and sulfur, carbon is a building block of biochemical molecules ranging from fats, proteins, and carbohydrates . Carbon dating to determine the age of fossil remains. In this section we will explore the use of carbon dating to determine the age of fossil remains.

Carbon Equilibrium Activity Since living organisms continually exchange carbon with the atmosphere in the form of carbon dioxide, the ratio of C to C approaches that of the atmosphere. Yet there are no very old, widely expanded Stage 3 SNRs, and few moderately old Stage 1 ones in our galaxy, the Milky Way, or in its satellite galaxies, the Magellanic Clouds. The level of proof demanded for such stories seems to be much less than for studies in the empirical sciences, such as physics, chemistry, molecular biology, physiology, etc. The sea is not nearly salty enough for this to have been happening for billions of years.
