What are your thoughts on dark matter?

[Swa]

We can't see dark matter, but we can detect it by its effects on normal matter through gravity and by the X-rays emitted by hot, dark matter.

Two options:
1. Something is fundamentally wrong with our understanding of gravity and rotation. Unlikely as this has withstood many tests for centuries
or
2. Galaxies and galactic clusters must contain dark matter and far more of it than light matter.

There are other proposed explanations for the gravitational effects and x-ray emissions. Something is being detected but it's not necessarily dark matter. To draw this conclusion is like somebody going to the doctor with a cough and the doctor asking them when they contracted Ebola. It's only a possibility but to say it's the most likely possibility before ruling out other possibilities is jumping the gun. See here how the charge field can fully explain dark matter.

1. Something IS fundamentally wrong with our understanding of gravity and rotation. If it all worked out perfectly nobody would be searching for the "dark" portion of the universe in the first place. Speaking of portions it seems nobody can actually agree on how much it's supposed to be ranging from 10% to 95% of the mass of the universe. The interesting thing is that dark matter wasn't the unwanted phenomenon it's made out to be. It was proposed way back in 1930 already to account for discrepancies in the big bang theory and cosmologists actually went searching for its effects. Another fudge factor in the big bang theory to account for galaxies not flying apart like predicted. In a near steady state universe these gravitational effects pretty much disappears.

2. Why do only galaxies and clusters contain dark matter? If it happens to be there and in the quantities claimed it should be everywhere including in our own solar system, yet no observation of it so far. So two discrepancies in the BB theory, namely why do ordinary matter clump together in the way seen and why to dark matter do it as well. Here's an explanation that doesn't require dark matter and also explains why the missing mass is only found in the outskirts. Amazing how nobody even knows how much matter our universe contains or where it is yet magical fairy dust is supposed to explain it all.
