Couple of years back I stumbled on an article describing what appears to be a huge cosmic trumpet: acoustic standing wave between two galaxies.
When I find it again I will post the link here

Wow... to mention a plasma universe without talking about charge separation, current, magnetic fields, birkeland currents once... and to rely on acoustic properties only? absolutely bizarre...

Has this guy even read Alfven or Peratt?

380000 years later, when the plasma has cooled enough for neutral hydrogen to survive.

The 'plasma' are a "hot gas" analogies are where it all regularly comes unstuck...

The universe is clearly observed as magnetic and full of charge separation, why do they continue to use the "hot gas" analogies and ignore the role of charge separation, and not even mention birkeland currents?

Ahwell I suppose atleast they use the word "plasma".... just need to now use the properties of the state... then they'll be able to do away with this Dark Matter, Dark Energy nonsense, by using lab verified filamentary forming properties, that continue to be OBSERVED!

Thanks for the link... good to see the gradual adoption of 'plasma' terminology, even if not entirely as Alfven describes.
