okay, good. actually at another time i was staring at the more general equation and had a few questions regarding it. so 1/H is the Hubble Time and about the age of the universe (maybe a milli-smidgen longer). this has been measured independently (from astronomical observation), right? and the density of the universe can be sorta guesstimated independently from astronomical observation (from estimating the number of galaxies, about 1011 and star systems per average galaxy 1010 or 1011 and then some average mass each plus whatever dark matter that i dunno how they measure or estimate and finally divide by the Hubble Volume, (c/H)3 ), right? that would say that, in whatever system of units, G could be estimated from astronomical observation. but it can also be independently measured (using the same system of units) with a Cavendish-like experiment. if these two values come out differently, is this how they determine the comological constant? someone please illuminate.
