And when you say theres not enough matter toale the large scale structures that's where the magnetic fields come into play.

Are we still talking about 'regular matter?'
If so, it's ruled out for the reasons I've already mentioned.
Astronomers are using Hubble Space Telescope to carefully measure distortions of shapes of distant galaxies by gravitational lensing produced by dark matter.
They're creating all -sky maps of it's location.
Gravity affects light.
Gravity affects light cones coming from distant sources.
There are Eddington Coordinates which reveal how light cones vary with distance from a source of a gravitational field, creating map distortion, time delays, as predicted by Irving Shapiro in 1964.
The gravity of rotating bodies ( Parker Spiral ) has a twist, and nearby bodies are dragged around... and disturbances in the gravitational field travel through empty space as waves... ripples in spacetime, spacetime geometry.
Gravitational waves carry energy.
These waves are literally altering orbital periods of pulsars, validating the predictive capability Einstein's general relativity.
Energy and mass and time are all related.
Disturbances of light, radio, x-ray, gamma-ray, infrared, UV... all travel through empty space at the speed of light. Relativistic velocity.
Dark matter has a gravitosphere if you will. It produces tidal effects throughout the entire universe.
Science is mathematics. Cosmologists have only mathematical models with which to 'define' the universe.
Without microscopes, COVID-19 is just a 'theory'. No scientists ever 'saw' Covid with the naked eye. And Covid will kill millions without ever being 'seen'.
I can detect current in a live conductor with a clamp-on AMPROBE. I don't need to cut the insulation away and attempt to 'see' it.
We can 'detect' dark matter, without seeing it. It 'infects' and 'inflames' the light coming from distant sources.
