...try ddg...Is most of the matter in the universe plasma?
All of course held together by gravity.. " Plasma makes up the sun and stars, and it is the most common state of matter in the universe as a whole. "

Yes, as per the links dmoe gave.Is most of the matter in the universe plasma?
Electromagnetism can ionise gases, yes.or
electromagnetism?
Good point (same point as made by mathman) . Most of the normal matter seems to be plasma, in stars, but if it is the case that 85% of matter in the universe is dark matter, then that is not plasma, or not as we know it, Jim.Most of the matter in the universe is DARK.
I assume it is DARK PLASMA.
But then I begin to feel less sure.
Plasma, like the other states of matter, is only defined for normal matter.ok because plasma has a charge
then
it is detectable
and then
it is not dark............?

In which case the answer to the OP question becomes "no".
Since WE DO NOT KNOW what Dark Matter is and honestly, WE DO NOT KNOW if it even exists, then like you stated "we cannot make any comment about what states of matter may apply to it."Since we have no idea what dark matter is, we cannot make any comment about what states of matter may apply to it.
Good point. Earlier posts in this thread talk about the percentage of visible matter that is plasma.Most of the matter in the universe is DARK.
We do actually. DM cannot be a plasma (defined as a gas of electrically ionized particles), for the obvious reason a plasma interacts with and scatters/refracts EM radiation. Hence is not 'dark' as in utterly transparent to light or other EM radiation. DM has only ever been 'observed' via its gravitational influence, in particular lately via gravitational lensing.Good point. Earlier posts in this thread talk about the percentage of visible matter that is plasma.
Since nobody knows for sure what dark matter is, yet, we don't know whether it is plasma or not, as several other posters have already said.
Excuse my ignorance, but doesn't Normal Matter in any of it's states(solid, gas, plasma, etc) interact with EM radiation?We do actually. DM cannot be a plasma (defined as a gas of electrically ionized particles), for the obvious reason a plasma interacts with and scatters/refracts EM radiation. Hence is not 'dark' as in utterly transparent to light or other EM radiation. DM has only ever been 'observed' via its gravitational influence, in particular lately via gravitational lensing.
Wikipedia is a great source of info on DM:Okay, Normal Matter, ionised or not, interacts with EM radiation.
Is that correct?
Yet this Mythical DM supposedly does NOT interact with EM radiation.
Is that correct?
So, if we cannot explain why this DM does NOT interact with EM radiation, how can we possibly KNOW that a gas of ionised DM particles WOULD interact with EM radiation?
