Scientific Essay from the year 2016 in the subject Physics - Astronomy, language: English, abstract: This paper presents a new concept for particle physics, which leads to a new concept for the universe and theories in physics. That concept is that the fundamental particle in the universe is a Dark Matter (DM) particle, and our matter consists of excited DM particles. The excited DM particles are theorized as formed in small regions of the universe where DM particles have been concentrated via gravitational attraction, which also acts to concentrate gravitational potential energy. These high-energy DM concentrations energize DM particles, creating the electromagnetic fields, which forms our matter and our sub-universe. The DM particles only interact via a gravitational field; however, the excited DM is theorized to also create the electromagnetic force. The weak and strong nuclear forces are theorized as an edifice of the DM basic bubble like structure. All matter is composed of only two items, DM and energy. All particles are composed of different combinations of these two items. The greater universe is an even distribution of DM particles with all energy stored as gravitational potential. Our sub-universe is a concentration of DM and energy. The energy flows back to lower energy regions in the universe following the same principle as the thermodynamic laws. The energy flows back to the universe's lower energy regions via excited DM particles, creating the appearance of an expanding universe. Thus we live in two universes, an infinite DM universe and a finite sub-universe composed of our matter with both universes sharing the same space, time, energy, gravity and DM particles. This theory has major implications in "a theory of the universe," particle physics and general physics. This simple assumption provides alternate theories to many of current accepted theories. The model presented herein is less complex than the current Standard Model, origin of the uni
