Can Dark Matter be in the form of Plasma?
A plasma consists of electrically conductive soups of charged particles that respond collectively to electromagnetic forces and are overall (quasi) neutral. If these particles were much more massive or of higher energy, they would not be detectable. According to plasma metaphysics, a significant proportion of dark matter is in the form of a plasma of super (high energy) particles.
In the "dark current mode" of plasma, the strength of the electrical current within a plasma is very low. The plasma does not glow and is essentially invisible. The plasma would not be detected unless its electrical activity was measured with sensitive instruments. Note that the ability to detect the matter rests on the sensitivity of the instrument. If we did not have the relevant instruments, these currents would have to be classified as dark matter i.e. as dark plasma. The magnetospheres of the planets are examples of plasmas operating in the dark current mode. Nevertheless, there is much more "dark plasma" in the universe. Dark plasma emits radiation that cannot be detected by our current scientific instruments. For example, the web of filamentary currents carrying hot plasma, cited in the author's article Acupuncture Meridians and the Cosmic Spider Web, is invisible. (Hence, by definition, they are components of dark matter.) They are detected only when ordinary matter, which condenses around them, gives out detectable radiation.
"Plasmas are not just the 'fourth state of matter' - they are really the first state in modern cosmology, and they continue to be, by far, the dominant state of visible matter in the universe; perhaps also of invisible matter as well if so-called 'dark matter' continues to remain unobserved and unexplained." - Timothy Eastman, President, Plasmas International
Intergalactic Magnetic Fields
The natural tendency of plasma to carry currents is an important source of magnetic fields. We know from basic electromagnetics that currents generate magnetic fields around them. (For example, currents circulating in the Earth's core give rise to the Earth's magnetic field.) Since plasma is pervasive throughout the universe, scientists believe that virtually all visible matter in the universe is magnetized. But magnetic fields are also found outside galaxy clusters where there is no visible matter. Where did these fields come from? The origin of these magnetic fields is still a puzzle to scientists. Are these magnetic fields generated by the equally pervasive dark matter? If so, the evidence points to dark plasma which would have the ability to generate magnetic and electric fields. Both gravitational and magnetic fields and anomalies, not accounted for by visible matter, may be indirect evidence of dark invisible matter composed of the lightest super particles.
Similarities between Dark Matter and Plasma
Consider the observed properties of space plasma, compared with dark matter:
a. Low Particle Density, Diffused, Collisionless
The particle density of dark matter is low, which correlates well with the low particle density in space plasma. (Many types of plasma are low density since they are composed of soups of particles of like charges which naturally repel each other within the soup.) Dark matter is said to be ‘diffused’ – so is magnetic plasma in our universe. Supersymmetric particles like WIMPs form a pervasive sea of diffused matter. Dark matter has also been described as "non-atomic" – this points directly to plasma. Dark matter objects are supposed to pass right through each other, just like objects in collisionless plasma. Magnetic plasma of different densities and other properties naturally separate into different regions, with denser matter separating from the more tenuous matter — so does dark matter, based on studies of its density distribution in galaxies.
b. Structure of Dark Matter Halos versus Plasma Crystals
Dark matter is also present in the halos of elliptical galaxies. These elliptical galaxies reveal the presence of faint shells on deep photographic plates which extend out to two or three times further than the bulk of the starlight. As many as 20 shells have been discovered around one bright galaxy. Computer simulations result in a similar array of concentric shells. Shell structures have also been found in other galaxies – and also in plasma crystals.
H Thomas and his colleagues have generated plasma crystals in the laboratory. These crystals were in the form of assemblies of particles which were held in a crystal-like array by a plasma of weakly ionized gas. When the assembly of microscopic particles was contained between two electrodes and illuminated by a laser beam, it could be seen, even with the naked eye, that the particles naturally arranged themselves regularly into as many as 18 planes parallel to the electrodes. In another more recent experiment, the particles in a plasma crystal arranged themselves into neat concentric shells, to a total ball diameter of several millimeters. These orderly Coulomb balls, consisting of aligned, concentric shells of dust particles, survived for long periods. The presence of concentric shells in the structure of plasma crystals and dark matter halos suggest that the dynamics in these crystals and halos are the same - both arise from the dynamics of magnetic plasma.
Conclusion
The evidence strongly suggests that a significant proportion of dark matter is in the form of magnetic plasma.
