The hypothesis is based on the possibility of transformation of a Sirius satellite (Sirius B) from a red giant in the past to a white dwarf in the present. Such a transformation would have been accompanied by an explosion of Sirius B, which is clearly visible from the Earth. The fact that the increase in Sirius brightness by 4-5 units is not reflected in historical chronicles is attributed to the degradation of sciences in Europe in 4-10 centuries. %0Journal Article %N;Journal ID: CODEN: ZEVSA %1 %CUSSR %Rhttps://doi.org/ Journal ID: CODEN: ZEVSA INIS %GRussian
