The scientific theory of Plasma Cosmology is that of Hannes Olof Gösta Alfvén. This was expanded upon by Anthony Peratt, especially in the area of galaxy formation.

But the "plasma cosmology" that has emerged in this thread is not Plasma Cosmology and is not a scientific theory. Since it's proponents claim that it is a scientific theory that makes it crackpottery.

The definition of "plasma cosmology"is that it is a collection of scientific theories (not one consistent scientific theory) with a common thread. This thread seems to be that the theory either emphasizes the contribution of plasma in the universe or is a steady state cosmological theory.

This collection allows the addition of any new theory that matches the criteria regardless of consistency with existing theories in the collection. Thus the collection allows:
  • Multiple inconsistent theories on cosmological redshift.
  • Multiple inconsistent theories on the cosmic microwave background.
  • Multiple inconsistent theories on the structure of the universe.
  • Multiple inconsistent theories on stellar formation.
  • Multiple inconsistent theories on anything else that is contained in "plasma cosmology"
The PC collection includes: There seems to be an emphasis on the extension of laboratory experiments in theory to large sizes via plasma scaling (ignoring the problems with this - see the Astrophysical application section). The observational evidence for this scaling has some gaps in it.

pc completely forgets about the laboratory experiments on gravity that can be scaled in theory without any problems to cosmic scales. The observational evidence for this scaling has some gaps in it.

Your list is silly Reality Check. Not all those publications are core areas of PC. Many of them merely act as supporting evidence of one aspect of plasma cosmology. Many of them merely demonstrate that plasma scaling exists, and thus is a valid aspect of plasma cosmology which many of the models are based on. Many of them merely demonstrate the importance of plasma in the the universe, which is often overlooked by BB exclusively gravitationally based theories, but central to plasma cosmology. They are no more core aspects of plasma cosmology than the orbit of Neptune is to the Big Bang.

So, lets have another go. You say we need to give comparisons between PC and BBT to see what they predict differently.

Maybe listening to Lerner and Peratts breif overview here would be a good idea to start with:

BBT: The universe is assumed to have a beginning and an end in time.
PC: The universe is assumed infinite in time and constantly evolving.

BBT: The universe originated from a highly homogeneous state and will remain largely so in the future.
PC: The universe is filamentary and clumpy. The large scale structure of the cosmos will not be homogeneous but highly filamentary.

BBT: CMB radiation will be isotropic.
PC: The CMB will not be entirely isotropic, certianly not the extent the Big Bang originally predicted.

BBT: The anisotropy of the CBR will be random, due mainly to the properties of the gravitational field.
PC: The anisotropy of the CBR will show a strong preferred orientation in the sky. Mainly due to magnetic anisotropy which occurs in a plasma, so that its magnetic field is oriented in a preferred direction.

BBT: The universe is nearly entirely electrically neutral and so EM and plasma considerations do not effect any gravitationally based models at all. The large charge separation we notice on Earth and in our local environment is just magic and a special unique event.
PC: Charge separation occurs in outer space due to various complex non linear plasma characteristics.

BBT: Energy can be created instantaneously out of nothing.
PC: Energy can not be created out of nothing, in accordance with conservation of energy.

BBT: The dark energy field can create energy out of nothing.
PC: Bollocks.

BBT: We can abandon common sense and known physics to explain contradictory observations.
PC: We must stick to well known, testable, provable, laboratory based verifiable physics, without adding ptolemaic epicycles to explain observations and conflicting observations.

There probably a few more about primordial elements too, etc. I'll get back to this list in a bit.
