An idea or concept which violates the very principles of cosmology is meaningless.

Cosmology is based on a mathematical principle that the scale of the Universe is expanding instead of the Universe expanding into existing space.

If the later occurred we would find the recession velocity is independent of the distance of the observer from the object, in other words each object would be moving away at the same recession velocity which contradicts observation.

The other issue is that a Universe expanding into existing space would require the Earth to be the geometrical centre of the Universe, which violates the cosmological principle.

Redshift is a direct consequence of this cosmological scale factor.
