Some cosmologists teach that space inside galaxies and galactic clusters does not expand at all. They reject the scenario in which expansion inside galaxies and galactic clusters is actual but is overcome by gravitational attraction and other forces. According to their theory, even the slightest gravitational attraction blocks any expansion:
"Space DOES NOT Expand Everywhere...Is the space inside, say, a galaxy growing but overcome by the gravitational attraction between the stars? The answer is no. Space within any gravitationally bound system is unaffected by the surrounding expansion."

Sabine Hossenfelder: "The solution of general relativity that describes the expanding universe is a solution on average; it is good only on very large distances. But the solutions that describe galaxies are different - and just don't expand. It's not that galaxies expand unnoticeably, they just don't. The full solution, then, is both stitched together: Expanding space between non-expanding galaxies...It is only somewhere beyond the scales of galaxy clusters that expansion takes over." https://www.forbes.com/sites/starts...ont-actually-expand-in-an-expanding-universe/
Other cosmologists teach the opposite. Expansion inside galaxies and galactic clusters is actual but is overcome by gravitational attraction and other forces:

Clearly, there is no viable theory of expansion. Cosmologists just fool the gullible world and eat taxpayers' money.
