原始语种摘要: The observations of the M87 jet with the STIS instrument mounted on board the Hubble Space Telescope revealed that an outburst originating in the HST-1 knot occurred. Measuring the dimensions of the outburst in the epochs between 2001 July 30 and 2003 July 27 and correcting for optical illusion an expansion velocity v/c = 0.99893 ± 0.00007 is found. However, the relativistic model fails to correctly predict the dimensions of the source and the outburst brightness. For this reason, as the apparent motion suggests, a superluminal mechanical model where even the light rays travel faster than light is introduced. By applying this model to correct for optical illusion an expansion velocity v/c = 21.8 ± 0.7 is found along with reasonable source dimensions and brightness. This result, the study...
