If dark matter was observational how would we see the universe

Could we see the universe at all if Dark matter were visible? I would think not if it makes up so much matter in the universe. Thoughts

Galaxies would be a lot brighter.

I wander if Dark matter could be observable in another dimension, and so because of the density it would block our observation of the universe. thank you for your response.

In science, a hypothesis has value only if it can at least in principle be tested by an observation that could be made. Can you conceive of an observation that could test your hypothesis? If not, it probably isn’t scientific.
