Description
Even from the very name, the international collaboration Event Horizon Telescope may suggest that the stellar objects hidden within the observed shadow are necessarily black holes safely covered inside a trapped region. However, on a purely classical level, one can exhibit models determining a shadow without a horizon. Recent speculations on possible alternative interpretations of the objects as those analyzed by the EHT collaboration will be discussed.
