The presence of gravitational field is taken into account. According to the results of the developed by the author theory, a particle with the rest energy $E_{0}$ would achieve the velocity of light if given the energy of about $E \sim 10^{3}E_{0}$RevTeX, 3 pagesGeneral Relativity and Quantum CosmologySpace Physicstext
