So true! Just to show how much so, here’s another hypothesis!

Time dilation! As time itself emerges from space/gravity, mass and distance could introduce a “time dilation” fudge that cosmologists attribute to “dark energy/matter”!

It may be our lack of understanding of time itself that changes factors of how we calculate the cosmological expansion/contraction and other mass stability estimates.

I too find it funny that we can wrap up our ignorance into a concept and call it dark*(whatever)!

My 2 cents : I have also a simple idea about time dilation explaining the dark matter, but I did not look out for numbers to check if it's plausible. Simply put : the center of a galaxy is the most massive part, often hosting a blackhole, and it's so massive that time runs slower than the outer part which is lighter, giving the impression on the outside (us looking from far away) that the galaxy rotates at the same speed in the center and in the outer part.
