Physics / Fundamentals

Galileo at age 38. Every substance has the property of 'mass', which is the basic physical presence of matter. Matter occupies space. A physical mass contained within a physical space produces the physical property of ' continue reading this fact

 Carbon Dating From The Skies
Physics / Radioactivity

Carbon dating the bones of an animal can pinpoint the time this animal died to within a few years. Determining the age of relatively recent fossils, those of plants and animals that lived tens of thousands of years ago, is not a guessing game but an exact science. By using carbon dating we can dete continue reading this fact
