G is the universal gravitational constant with a value of 6.674 × 10-11Nm2kg-2. m1is the mass of one massive body measured in kg. m2is the mass of another massive body measured in kg. r is the separation between them measured in kilometre (Km). ...
In newtonian gravitation, G is an absolute constant, independent of time, place, and the chemical composition of the masses involved. Partial confirmation of this was provided before Newton's time by the experiment attributed to Galileo in which different weights released simultaneously from the top...
following: (1) Accelerated radial expansion of our universe; the present rate of radial expansion computed from Hubble's law, the radius having order of magnitude of 1010 light years, has order of magnitude ρ1017 km/sec, where ρ is constant of proportionality that still needs to be ...

where G=6.673×10-11 m3/kg*s2 (or N*m2/kg2) is called the gravitational constant, m1 and m2 are the masses (in kg) of the two objects attracted to each other, and r is the distance (in m) between the centers of the two objects. Gravitational forces are vectors, denoted here ...
