In a counterpart of General Relatlvity called Field Theory of Gravitation where spacetime is really flat and spin-2 fields cause gravity. See:(adsbygoogle = window.adsbygoogle || []).push({});

Space is already there as the following description state:

"Cosmology is another field of application of gravitation theory. Present data about large scale galaxies distribution contradict to the main point of Friedmann cosmology — its homogeneity. It turned out that galaxies form a fractal structure with dimension close to 2 at least up to the distance scales bout 200 Mpc. This leads to a new possibilities in cosmology (see an analysis of FTG cosmological applications in the review of Baryshev et al., 1994). One of the main difference between FTG and GR is that the field approach allows the existence of the infinite stationary matter distribution (Baryshev, Kovalevskij, 1990). In a stationary fractal distribution the observed redshift has gravitational and Doppler nature and is not connected with space expansion as in Friedmann model."

Is there a possibility the above is the case and space didn't really expand but as I interpretated from the above.. space is already there? Or is space expansion 100% proven already beyond the shadow of a doubt? Thanks.
