I fully understand the behavior of physical phenomena, thats why it surprises me that how such a colossus intelligence (combined) is pursuing something unphysical like Black Holes, Worm Holes and Time Travel. (You tried to side step the time travel in most trivial way, while knowing fully well what I was referring to. don't you know what authority is talking about ? They are talking about... A. We do not know how to solve GR equations for more than two bodies. B. We do not know what happens to mass once it goes inside the EH. C. May be it will enter the new universe, may be it will squeeze to a point. D. We know that time travel is possible, and we can go back in the past and kill our grandpa before our pa is born. E. We do not know how the mass curves spacetime, but it curves. F. We do not know how the spacetime tells mass to move, but it does. G. We do not know how the universe is expanding at very very high speed, but it does. H. We know that in maths we cannot divide by zero, but to get BH we can do that. And by the way, your knowledge of maths, is to be respected, there is at least one more guy Schmelzer who is at par, most others are just the followers, blind supporters. I know my maths and Physics well enough to say that GR in its present form is not the done thing for Physics. I also know that GR maths holds the key to truth. The real theory will certainly use the GR maths not the philosophy or concept behind. Anyways peace, because this argument is not going to take us any farther as on date...Will have to wait till 2025.
