I doubt that it has ever occurred to any competent relativist that the event horizon might be "a wall." Therefore it would never have occurred to them in a flash of blinding insight that it was "not a wall."Has this ever occurred to anybody? The Schwarzschild limit is the spot that the escape velocity is light speed. It is not a wall. What escape velocity means is that if a body is not going that speed, it will not escape. It is not a wall.
See my post #35 here, the event horizon cannot be understood purely in terms of the classical notion of escape velocity. In any case this argument of yours is totally off-topic for this thread, please try to stick to discussing things directly related to the opening post of whatever thread you're on--if you want to a new thread to discuss some issue you're interested in, there's a "new topic" button on the upper left of the main page for the relativity forum. Also please note the IMPORTANT! Read before posting note, this forum is not a place to dispute the validity of relativity, although you can ask questions about things that don't make sense to you as long as you are open-minded about the idea that it would make sense if you understood the subject better.Then if it is not a wall (something did think a little obvious) then why can't particles/objects/radiation not get out?
