Know plasma, know 99.999% of the Universe
The Plasma Universe is a term coined by Hannes Alfvén to "... emphasize the fact that plasma phenomenon discovered in the laboratory and in accessible regions of space, must be important also in the rest of the universe".
Some estimates suggest that 99% of the visible universe is plasma, and an even greater percentage by volume. So to know plasma, is to know the universe. </p>
The Top 5 cosmic plasma misconceptions
- Gravity is the dominant force in the Universe"
The electromagnetic force, affects charged particles up to 1039 more strongly than gravity. For example, a singly charged hydrogen atom (ie. a proton) is affected by the Earth's magnetic field 10-million times greater than the influence of gravity.
- The Equal numbers of charged particles in a plasma neutralise one another
Plasma is "quasineutral" meaning that it tends to be electrically neutral. But double layers (charge separation regions) and plasma particle beams, both violate quasineutrality
- Cosmic plasmas are too tenuous to conduct electricity
Field-aligned "Birkeland" currents are independent of the plasma density, and even the interplanetary medium is as conductive as a metal. The largest structure in the Solar System, the heliospheric current sheet, carries 3 x 109 Amps. An estimated 1019 Amps may flow in the galactic plane
- Cosmic plasma is only a fluid-like ionized gas
While cosmic plasma may behave like a fluid-like gas, many phenomnena are unique such as (a) reaction to electromagnetic forces (b) filamentation (c) self-generating magnetic fields and electric currents (d) tendency to cellularise regions of different properties (e) formation of particle beams
- Cosmic Plasma theory is not well-developed
Peer-reviewed published theories may explain aspects of (a) cosmology, without a Big Bang (b) Galaxy formation, without dark matter (c) Star formation, as a "plasma pinch" (d) Chemical separation in space (e) "Invisible" energy transfer (f) planetary rings (g) "Jets" (h) Synchrotron radiation (i) cosmic rays
