Dark matter: The invisible force The temperature of space may hold the key to solve problem of missing matter Dark matter, the "invisible" mass that scientists believe makes up a large part of the universe, can be explained as being mass that is at one end of a cooling process that all matter goes through. Before getting into this theory, it must be noted that due to the undetectable nature of dark matter, applied science is not an option in reaching an explanation. That leaves logical reasoning, using well known facts, as a best bet in pursuing a conclusion. That being said, take the following three statements as givens: 1. Dark matter exists, but we do not know what it is. 2. Subatomic particles of an atom -- the protons, neutrons and electrons -- all have mass and energy. 3. All matter in motion uses energy and follows the laws of thermodynamics. On to the theory. It is a cooling theory, based on the idea that mass is a permanent entity, and the energy associated with mass is necessary only for matter that can be detected. Mass without such energy is the invisible dark matter. The mass is all there -- but what kind of matter it becomes depends on temperature. Once matter reaches zero degrees Kelvin, it ceases to be detectable – and becomes part of the missing mass that scientists cannot account for. Imagine that the universe is composed of matter that is always in the process of moving from an invisible, dark-matter state into an energized – and detectable -- state and then back again. Through the natural process of cooling, the process where active matter radiates thermal energy till all energy charge is spent. The subatomic particles of an atom – the protons, neutrons and electrons -- will use up the available energy and eventually reach 0K. When the matter reaches 0K, the mass of subatomic particles enter a neutral, undetectable state, having no particles in motion and therefore no thermal radiation. In that environment, the mass of an atom remains. And while it would lack any thermal energy, it would maintain a gravitational force, and thus a potential source of Kinetic energy. Instead of the term "dark matter," consider this to be a "neutral mass." It is mass in a stable state, that requires an occurrence involving extremely high energy acting upon the mass to set the subatomic particles in motion and recreate the atomic structure. The neutral mass has a gravitational force and ability to attract other masses, producing kinetic energy with a cumulative effect that could be quite substantial. A large concentration of this neutral mass would manifest as a black hole. Two black holes colliding -- bodies of dense, compacted neutral mass, each with enormous gravitational force and kinetic energy -- could yield an explosive action that would re-energize the atomic structure. That could take the form of new galaxies, which in turn are the elementary building blocks of the universe.
