    "abstract": "New approach to the description of a gravitation using analogy between the\noptical and mechanical phenomenon is advanced. For this purpose in extended\n(1+4)-dimensional space G(1,4) the gravitational effects are considered: the\nspeed of escape, red shift, radar echo, deviation light and perihelion\nprecession of Mercury. It is shown, that methods of the Extended Space Model\n(ESM) give the same outcomes, as General Theory of Relativity (GR). The various\nways of introduction of refraction index are discussed, which appropriate to\nthe gravitational field.",
