Matter and Energy

Another point is the Conservation of of Matter and Energy. The Universe is a closed system and as such, contains a finite amount of matter and energy. Energy can neither be created nor destroyed. Matter and energy are interconnected by Einstein's famous equation, e = mc². E or energy equals the mass (m) of a substance (similar to its weight) times the square of the speed of light (c). Each atom contains a great amount of energy that holds it together. Some of this energy is released or is increased when atoms join together to make molecules or participate in chemical reactions.
