Today I thought about what would happen if you swapped ordinary and dark matter.
But to make things simpler, I'll give you some analogies.
Imagine the Universe is a house you're building. There are two important materials in this house: ordinary matter (bricks) and dark matter (the frame). Ordinary matter is what we can see: stars, planets, gas. Dark matter is invisible, but it’s abundant and holds the entire structure of the Universe together.
Currently, there is much more dark matter than ordinary matter in our Universe. This helps stars and galaxies move in predictable ways, and gravity is distributed evenly. Without dark matter, galaxies and stars wouldn’t have formed the way we see them.
Now, imagine we swap them: ordinary matter becomes abundant, and dark matter is almost gone. This would drastically change the situation. With a lot of ordinary matter, galaxies would become bright and dense, but without a strong framework (dark matter), they would be less stable. The structure of the Universe would change: in the centers of galaxies, stars would be bright and powerful, but at the edges, where there is less gravity, stars would move slower, and the galaxies would be less stable.
So now you understand how important it is:)

You question absolutely makes sense

Oh I see I see you wanna deep in this shit. You will get it next time! ;)

I’m curious - what math describes the existence of dark matter? If my question doesn’t make sense, consider the analogy that parallel universes are the result of following the math of black holes - is it the same for dark matter? What about dark energy?
