Completeness’ problem of being transmitted information

This article presents an investigation of completeness’ problem of information transmitted by spherical electromagnetic wave from source to receiver. A space–time curvature caused by electromagnetic wave is an origin that influences on completeness. It is shown that that curvature has two parts, gravitational and diffractional ones. Light beam scattering parameters such as scattering angle and capture cross-section due to curvature of space-time are evaluated. It is shown that transmission of information from the Past to the Future with the help of spherical electromagnetic waves has quantum character.
