The parameters of maximum iteration T, population size N, initial gravitational constant [G.
Physics shows that all the basic phenomena of nature and the laws that govern them have particular constants or ratios associated with them--the gravitational constant, the electric charge, the mass of the electron, Planck's constant from quantum mechanics, and others.
Dirac developed a cosmology where the gravitational constant decreased with time and matter was created where matter existed.
Because the gravitational constant G, the mass of the earth m, the average radius of the earth R, the light velocity v and The height of the satellite h are all known, so we get:
i) The initial spectrum of UCN entering the system is a Maxwell spectrum cut from above by the critical energy for LTF at [approximately equal to]150 K (= 120 cm in units of E/mg with the neutron mass m and gravitational constant g [11]).
These fundamental constants of nature include alpha, the gravitational constant, and the speed of light in a vacuum.

It describes quintessence by using only simple constants of nature, such as the speed of light, the gravitational constant, and Planck's constant of quantum mechanics.
From the author's point of view this deviation originates from current uncertainty in gravitational constant (G) measurement.
Now we have an explanation for why we need the gravitational constant G.
One set of findings offers the most precise value thus far for the gravitational constant, so-called Big G, which relates mass and distance to the strength of gravity in Newton's law.
0] the gravitational constant, M the mass of the object, and r the radial distance from the object center; [rho] is the mass density of the object; h is the extinction coefficient.
Measuring the gravitational constant The news that three respected research groups had independently produced values for the strength of the gravitational force (G) that disagreed significantly with the currently accepted number and with each other created a considerable stir last year (SN: 4/29/95, p.
