For those who are interested in the problem of vacuum<\/strong><\/p>\n

The modern quantum theory states that there is a number of different contributions to the energy density of vacuum \u03c1vac<\/sub><\/em>. By far the greatest of them is given by the zero-point quantum fluctuations of fundamental bosons. Corresponding energy density is huge and is of the order of the Planck energy density \u03c1vac<\/sub><\/em> = <\/em>4.63 .10113 <\/sup>J\/m3<\/sup> <\/em>, which exceeds ca<\/em> 10120<\/sup> times the observed energy density of vacuum. All other contributions to\u00a0 \u03c1vac <\/sub><\/em>are incomparably smaller which does not allow one to explain the actual very small net value of \u03c1vac<\/sub><\/em> .<\/p>\n

\"\"<\/a>

The Figure shows the density of vacuum energy in dependence of the concentration of the fluctuations with a negative energy.<\/p><\/div>\n

In arXiv a publication [1] by V. Hizhnyakov has appeared, which among other things considers the vacuum energy density (Appendix I). The author examines the possibility of compensating the huge energy of fundamental bosons\u2019 zero-point fluctuations by other Blanck-scale fluctuations which are with negative energy. The proposed model allows also to give the value of the Higgs boson mass in good agreement with the recent measurements (Appendix II).<\/p>\n

The Figure shows the density of vacuum energy \u03c1vac<\/sub><\/em> in dependence of the concentration of the fluctuations with a negative energy; l0<\/sub> is the fluctuations\u2019 distance, lp<\/sub>=1.616* <\/em>10-35<\/sup> m is the Planck length, (the Figure is based on Fig.1 of the article). Concentration 0.29 corresponds to Tryons assumption [2] that the Universe has arisen from zero-energy quantum fluctuation.<\/p>\n
