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.8 pages, 5 figures, Latex; a comparison with the latest SN1a and GRB data is added in versions 3 and 4AstrophysicsGeneral Relativity and Quantum CosmologyHigh Energy Physics - TheoryHubble diagrams of soft and hard radiation sources in the graviton background: to an apparent contradiction between supernova 1a and gamma-ray burst observationstext
