Modern theories
For a long time, it was thought that the proton, neutron, and electron were the elementary particles, as well as the smallest. Since the Atomic Theory was formulated, many new particles have been discovered. The new theories concerning these particles and predicted particles attempts to explain every phenomena in physics. This is also called the Universal Theory of Matter.
Dark Matter and Dark Energy Dark matter is an assumed kind of matter which unlike ordinary matter does not emit or reflect enough light, X-rays or other electromagnetic radiation. Therefore, it is not directly detectable by our instruments. However many astrophysical evidences points to the presence of such matter. In fact dark matter supposedly is much more abundant than ordinary matter. The amount of observable matter in our Milky Way galaxy is only about twenty percent of the mass that is needed to keep the system stable and holds on to the stars in the outer orbits of the galaxy. Therefore, it is conjectured that %80 percent of the matter in the Milky Way galaxy is dark matter. NASA speculates the origin and nature of dark matter as:
“Dark matter has been a nagging problem for astronomy for more than 30 years. Stars within galaxies and galaxies within clusters move in a way that indicates there is more matter there than we can see. This unseen matter seems to be in a spherical halo that extends probably 10 times farther than the visible stellar halo around galaxies. Early proposals that the invisible matter is comprised of burnt-out stars or heavy neutrinos have not panned out, and the current favorite candidates are exotic particles variously called neutrilinos, axions or other hypothetical super symmetric particles. Because these exotic particles interact with ordinary matter through gravity only, not via electromagnetic waves, they emit no light.”38
The concept of dark matter has been presented because the observable mass of galaxies has
