Bulletin of Taras Shevchenko National University of Kyiv.

It is shown that from the assumption of a physical vacuum as a dielectric medium, the postulate of the constancy of speed of light follows in all inertial reference systems. The explanation of the partial capture of light by a moving medium (the effect of Fizeau), the effect of a gravitational lens, displacement of the spectrum of an electromagnetic wave in a gravitational field is given. The redshift of the spectrum of galaxies may have an alternative explanation not related to their expansion. As a result of this explanation there is no need to use the idea of dark energy.Key words: light, physical vacuum, virtual particles, gravitational lens, red shift, dark energy.Pages of the article in the issue: 95 - 98Language of the article: UkrainianenСтаття
