The mainstream used Newton’s formula (and its variations from Einstein and Schwarzschild) for gravitational acceleration a = G×M/R², circular velocity v = sqrt(G×M/R), and escape velocity ev = sqrt(2G×M/R), to say that for a massive and dense stellar object of great mass M and small radius R, escape velocity ev exceeds the speed of light c. But since velocities beyond the universal c-speed-limit are unachievable, that means nothing can escape such a dense object’s vicinity. That is how Black Holes appeared on paper, then on images. Problem with such explanation: time in such Black Holes stops, but time stopping requires infinite energy.
Fast forwarding to now. Dr. Vivian Robinson corrected gravitational formula: a = G×M/(R×D)² with D = exp(G×M/(R×c²)) factor, where D is time dilation (time slowing down) factor on the distance R from the mass M. With such correction neither circular nor escape velocity reaches c-limit. Thus, there are no holes in spacetime, meaning no Event Horizon. And time does not stop there — it just slows down by a factor D.
