  In the sea of super-strong interacting gravitons, non-forehead collisions
with gravitons deflect photons, and this deflection may differ for soft and
hard radiations. As a result, the Hubble diagram would not be a universal
function and it will have a different view for such sources as supernovae in
visible light and gamma-ray bursts. Observations of these two kinds are
compared here with the limit cases of the Hubble diagram.
