Supernovae type Ia: non-standard candles of the Universe
  We analyze the influence of the evolution of light absorbtion by grey dust in
SNe Ia host galaxies and the influence of the evolution of average total mass
of coalescing double carbon-oxygen white dwarfs (progenitors of SNe Ia) under
the influence of gravitational radiation on the interpretation of Hubble
diagrams of SNe Ia. Significant increase in the average energy of SNe Ia due to
increase in the total mass of merging dwarfs can be observed at red shift z> 2.
The observed dependence of the distance modulus from the red shift in
observations of SNe Ia can be explained not only by the assumption about
accelerated expansion of the Universe, but also by the evolution of the
absorbtion of light by grey dust in various types of host galaxies of SNe Ia,
by the effects of observational selection and by the decrease in the average
mass of coalescing degenerate dwarfs.
