A simple language uncovers the nature of the most mysterious space objects. Quasars, GRB, bright radiation sources, the dark substance, accelerated expansion of galaxies and many other things became clear thanks to the received space-time metric. Spectrums of these objects both their cores geometrical and physical properties are calculated. Exact mathematical deductions are disposed in appendices. For the first time explicitly the processes happening beyond the horizon of events are viewed. The author has shown that Universe expansion is not driving, and is a consequence of a metric modification. All deductions are confirmed by known experiments and introduction of additional hypotheses do not demand.
