The ultimate opposite mass must be the Planck mass and its opposite number, the other Planck mass. The situation with the Planck mass is that its Compton wavelength is equal to its Schwarzschild diameter. With this situation in mind the number 4.763120195x10^11 offers us a useful template. In the protonic situation the square of 4.763120196x10^11 is 2.2687314x10^23, the Compton frequency of the proton. With local protonic G, the GM product of 2.2687314x10^23 is 1.414199136x10^13. Its Schwarzschild radius is 3.14701749x10^-4m; which is 1/(1.009721668x10^7)^0.5. 1.009721668x10^7 is the ratio between proton mass and h/4, a very important number in this branch of physics and closely linked to the Planck mass.
(4.763120196x10^11)(29.6906036)=1.414199136x10^13, GM product. It doesn't matter what mass units we use, kilograms, protonic mass units, inbetweeners, etc, that GM product remains fixed as does the mass/multiplier, 4.763120196x10^11. Multiply 1.414199136x10^13 by 1.009721668x10^7, the proton mass/h/4 difference, and the GM product becomes 1.427947511x10^20 and the Schwarzschild radius becomes 3.177611789x10^3m, The square root of 1.009721668x10^7. You will see how important this becomes as time goes on.
The Sunlike GM product, 1.427947511x10^20, divided by 4.966118653x10^-26 equals 2.87537936x10^45. 4.966118653x10^-26 is hc/4 and is equal to Gm^2 where m^2 is equal to the Planck mass squared. Divide 2.87537936x10^45 into (c^2)/h and you get 4.71726031x10^4: multiply this by 1.009721668x10^7 and you get 4.763120196x10^11. Now, 4.763120196x10^11 divided by the inbetweener Planck mass, 2.822570503x10^-8, equals 1.687511504x10^19; divide this by 3.62994678, the Quantum Adjustor, and you get 4.648860166x10^18, which is the local c/G multiplier. by dividing this into c we wind up with 6.44873003x10^-11, the local, inbetweener, G.
(4.648860166x10^18)x(4.763120196x10^11)=2.214307975x10^30 which is the inbetweener mass where Schwarzschild radius is 3.177611789x10^3m, see above.
(2.214307975x10^30)/(1.672623x10^-27)=1.323853597x10^57. Now, the 1.672623x10^-27 used here is not the proton but the inbetweener value which is (proton mass)/(x)^0.5. Provided we keep everything proportional along these lines we will get the following result.
1/(1.323853597x10^57/3.177611789x10^3)=2.400274317x10^-54m. Which is the Schwarzschild radius of the inbetweener mass value, 1.672623x10^-27.
