Should retarded gravitational potentials being considered in cosmology ?

Question

Retarded gravitational potentials could help to understand and to explain what had happend during the expansion of our universe. They already had been successfully used for explaining the rotational curves of galaxies. No synchrotron would work without considering retarded electromagnetic potentials.

The Lambda-CDM model has to cope with more and more challenges, but it seems that alternative views such as retarded gravitation are not really considered by professional cosmologists. Why is this the case ?

Answer 1

Bousso,

tetarded gravitational potentials is not conceivable in the standard model of cosmology because the singular instanton never collides with the second explosion of a neutron star. it has to come from the supersymmetry breaking scale associated with the D5 brane workdvolume theory. h and alpha' corrections are (not?) required because the string decouples from the fundamental length scale of the M5 brane which is an F-string :/

in order to obtain an interactive

Answer 2

Therefore, the standard model of cosmology should be or even has to be exchanged and not only changed...
