Consensus Science, for the most part, looks on the universe as electrically neutral and purely mechanical; a place where the weak force of gravity holds fort. Plasma Cosmology, by contrast, acknowledges the electrodynamic nature of the universe. Gravity and inertia are NOT the only forces at work.

The history of science, of course, is fraught with controversy, and it is important to bear in mind that the situation today is little different.

Plasma is the fourth state of matter. It differs from solids, liquids and gases in so far as it's atoms are divided into free-floating 'negative' electrons and 'positive' ions (an atom which has lost its electron/s). It is sometimes referred to as an ionized gas.

Students are generally taught about only three states of matter, and when Plasma does get a mention, little importance is assigned. Not only should plasma be added to the list, but the order should be reversed to put it in first place. The reasons for this will become clear.

The term Plasma was borrowed from blood plasma in order to describe its almost life-like and self-organising properties.

Plasma sometimes emits light when under the excitation of electrical and magnetic fields. Polar auroras bear witness to this fact.

Plasma in space consists entirely of ions and electrons, and is thus very energetic or 'hot'. Only when cooled does it form the matter to which we are familiar here on Earth: solids, liquids, and gases.

Because plasma remains electrically charged in space, it is influenced more by electromagnetic forces than gravity. In fact space, once considered mostly empty, has been found to be alive with plasma. Vast flows of charged particles have been discovered spanning hundreds-of-thousands of light years across interstellar space.

The most familiar examples of electrical plasmas here on earth are neon signs and lighting, television screens, and electrical arc welding machines. Fire and Lightning are also forms of Plasma.

Just about everything! Plasma is an excellent conductor of electricity, and because of its free-flowing electrons its conductive properties far surpass those of copper and gold.

Due to its interaction with electromagnetism, plasmas display a complexity in structure far exceeding that of matter in gaseous, liquid, or solid states. It has a tendency to form into cellular and filamentary structures.

These structures derive from the fact that a charged particle flow (or current) produces a ring of magnetic fields around itself, 'pinching' plasma into multi-filamentary strands, as can be seen on both cosmic and more localised scales.
