"Existing space would be an absolute frame of reference for the Universe. Galaxies would be able to exceed the speed of light in this frame of reference."
That’s what I have been saying in this and other treads.
"Another consequence is that since galaxies are now travelling through space the inflation event would not have occurred shortly after the BB. The Universe would not have time to become large enough to prevent matter from collapsing onto itself due to gravity."
No one knows how big was the original object that caused Big Bang, or what was the velocity of the matter expelled by it. If the velocity has high enough the inertia should overcome gravitational collapse.
This scenario makes Big Bang theory more acceptable to me. Consequences of this would make General Relativity wrong.
