Space expansion allegedly confirmed by the Hubble redshift is radial with respect to the Earth's centre. But there must also be directly observable tangential expansion - celestial objects must move away from one another. No such movement has been observed, so there is no expansion.
"Reber (1982) pointed out that Hubble himself was never an advocate for the expanding universe idea. Indeed, it was Hubble who personally thought that a model universe based on the tired-light hypothesis is more simple and less irrational than a model universe based on an expanding spacetime geometry...any photon gradually loses its energy while traveling over a large distance in the vast space of the universe."

Dec. 14, 1936: "Other causes for the redshift were suggested, such as cosmic dust or a change in the nature of light over great stretches of space. Two years ago Dr. Hubble admitted that the expanding universe might be an illusion, but implied that this was a cautious and colorless view. Last week it was apparent that he had shifted his position even further away from a literal interpretation of the redshift, that he now regards the expanding universe as more improbable than a non-expanding one."
