In my text, even, they go thru Kruskal coords for Schwarzschild.
These fold time, like a 1/t, thru the event horizon. ELSEWHERE THE
SAME TEXT SEZ, SINCE AS A BODY FALLS IN TO AN EVENT HORIZON, THE TIME
GOES ASYMPTOTIC, .THEN FURTHER CONSIDERATION IS QUESTIONABLE. Yes, but
I have already characterized the scales as pretty small. Once I had a good time on a
science forum, and the main guy gave a solution for a black hole with
a moderate rate of growth, like a steady influx of mass rain. THAT’S A DIFFERENT STORY. Otherwise, I did work out the characteristic time constant, and it is not long… before too long, we are in “quantum mechanical” distances, and so our physics is questionable. STEPHEN HAWKING, where are you ??? Offhand I am not interested in a time scale going past the end of our universe, I am not quite THAT much of a mathematician.
