OUT OF THE BALLPARK

Typing these numbers is useful, g’mornin !! The chosen Schwarzschild radius of E4 meters can be divided by ‘c’ to get light-seconds, so R = 0.3 E-4.
In a year there are about 3 E7 seconds, so in these units, we seem small, with
R = E-11 lightyears.
THE BIG PICTURE::: If there are E12 galaxies, and each one hosts E9 black holes, that’s E21. My calcs say integrated all the way out, each one adds more than 20 radial units…
E-11 x 20 x E21 is 2 E10 . Oh shit… I AM SO RATTLED I UNDERFIGURED THIS.
= 2 E11 lyr.  Seems the Swiss cheese has more holes, than cheese…. This is a first, pretty dumb estimate. I need galaxy spacing.

YO, STEVE, GALAXY COUNT ??

Given the wide-angle sort of pic I hosted a few days ago of galaxies arrayed like tops, or stones, could we believe there are on the order of one trillion of them ??? This is a rough answer, given the Milky Way spreading about E5 lightyears. I take ten times this distance, which may be too small, to the next galaxy.

 

CURRENT PAPERS

Steve sends a 2011 paper by Kim Greist, with the correct integration for proper distance.  The result is used only for near-field study.  Very soon my brother and I will issue some VERY LARGE NUMBERS, of all the black holes ‘around’.
