- In the 1990ies, scientists discovered that the large scale space time curvature of the universe is flat.
- Hubble discovered in the 1950ies that all distant galaxies are red-shifted, i.e. moving away from us.
As the universe is not curved, it is no longer possible to postulate that “everywhere is the center” and if you fly long enough in one direction you come back from the other.
In a flat universe, either Earth is at the center and everything moves away from us – or we are not at the centre in which case we would be flying away from the centre in the same direction as some other galaxies – while other galaxies would fly away in the exact other direction, being much more redshifted than our immediate neighbours – relative velocities would vary wildly depending on trajectory.
Completely different possible explanation: Photons that reach us from outer space have lost some of their energy due to a phenomenon that has nothing to do with relative velocity. This would go the direction of MOND (modified Newtonian dynamics). Unfortunately for some it would also force a rethink of the Big Bang theory.
I got this observation from Dr. Sanford…. ca. 20:00 :
