[2] Unlike the other three states, solid , liquid , and gas , plasma does not exist freely on the Earth's surface under normal conditions. This branch of physics was necessitated by the discovery of the fact in the early 20th century that the laws of physics that govern matters of macroscopic scale do not function in the realm of microscopic objects. The Standard Model of particle physics is the theory describing three of the four known fundamental forces (the electromagnetic, weak, and strong interactions, and not including the gravitational force) in the universe, as well as classifying all known elementary particles. This energy comes from the splitting (fission) or joining (fusion) of atoms. 7 billion years to the big bang. org just a single type of information, then everything in the universe should be possible by it.
