The presentation deals with a discovery of errors in the Einstein’s General Relativity Theory (GRT). The presentation starts with the confirmation of the correctness of Special Relativity Theory (SRT), but derives justification for a different dependence of gravitational mass on velocity than the inertial mass dependence on velocity. This leads to finding that photons cannot have a gravitational mass and thus can escape form “Black Holes”. This finding contradicts the popular belief and the popular statements such as: “not even light can escape from Black Holes”. The presentation then introduces a new metric whose validity has been confirmed by the standard GRT tests and applies it to create a new model of the universe, which is not based on the Big Bang assumption. Finally, the new universe model predictions are compared with observations and an excellent agreement is obtained thus confirming the assumptions on which the model is built.
