Hello Mark
Where does plasma come from?
Mate, in its true definition all is plasma.
Think about it.
Now the compacted cores that are found in star bodies is something special. Most of the Milky way mass is found in compacted cores.
There are varies ways to create this compacted matter.
By some form of gravity sinks throughout the galaxy being used to make a zone stable enough to hold compacted matter such as Neutrons. Starformation process.
Theoretical opinion.
The other is by black holes ejecting compacted matter, this type of matter is very special, a soccer ball size has the same mass as our sun. Elliptical galaxies are formed and structures by these active neucleons ejecting these gravity sinks. Imagine a few would make a cluster of stars.
Now imagine what this jet can form, like a wild hose ejecting matter thousands of light years into space. This is against main stream thought. So I’m uptream. Smile
