[Astronomy]

Magnetohydrodynamics - Omitting the electric field and other over-simplifications create false models. Things like like "Magnetic reconnection" do not really exist. Alfven already warned us.

Temperature of the sun's photosphere. - The electromagnetic activity gives a false impression. Neutral elements show normal low temperatures. link

Dark matter - Most of the papers are wrong, even if it does exist.

Redshift - can also be caused by interstellar plasma. In that case, light of high frequencies moves slower. link. Could interfere with inflation and dark energy. Dark energy is already spread like gas/plasma.


The problem with astronomy is that we have to build theoretical models on top of other theoretical models. And only fractions of it can be tested. We simply can not travel that far or look back in time. If we find a problem, it is too hard to revise the underlying models, so we add another theory.
