Default Turtles all the way down

One certainly hopes so.

Bell is arguing that the redshift measured in certain types of objects presents a distorted picture of how distant the objects are, and hence their size. There are very few astrophysicists who agree with Bell's interpretation of the data, but I think everyone agrees it is a puzzle that can be arranged in many different ways.

It is also worth mentioning that believing the universe sits on the back of a giant turtle is also a cosmology. In this respect, scientific cosmology is generally granted a little more license than most sciences, but not much. In theory this license ends when observations no longer agree with the cosmology. But it is really hard to prove the universe does not sit on the back of a giant turtle.
