COORDINATE CHOICES: EDDINGTON-FINKELSTEIN ??

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.

  1. Interesting about the asymptotic time. I saw Juan Maldecena talk about this and the way he puts it, events inside the black hole are always in the future for an external observer.

    • OK – in the case of Mercury with 43 arcseconds per century of perilhelion shift would this number change noticeably? What would the new value be if so?

      Interesting the effective gravity term is an inverse-cubed force instead of the usual inverse square. The latter doesn’t have a perihelion shift.
