New measurement of Hubble constant adds to cosmic mystery

the universe is supposedly expanding very rapidly, with objects moving very rapidly. I would imagine there is a huge bias that is probably wrong.

I understand gravitational lensing and all, but there are huge assumptions made about formations and clusters of celestial bodies where there is a lot of room for these crafted images of stars and black holes to be completely wrong.

What if there is no black hole but just points in the universe where there is so much clutter the light cannot jump around, leading physicist to believe there is a black hole?

Like when I shine my flashlight over a corner, sure you can see the shadow, what if you are two rooms away? Wouldn’t you not be able to see anything at all?

It seems we don’t know anything about the universe and rather than say the equations are wrong and look for more abstract formalizations with larger rooms for error, we continue to hold dogmatic practice to very strict and rigid formalizations. Don’t get me wrong quantum mechanics show the waviness of the world (both metaphorically and literally), it just seems based off of some assumptions we snowball. The snowball effect causes generations upon generations to practice dogma rather than facilitating questioning and looking for contradiction. It seems the physics community has fallen to a confirmation bias.
