F(C)=g
F=(MC^2=E)
F=(Mg^2=E)
F= [(5.98x10^24)(9.8)^2=(5.74x10^26)
F/ average mass of a human * planc's length of string (approximation) = G
F= (5.74 x 10^26) / ~86kg * 10^-35 = 6.673 x 10^-11
Mathematical Proof For G (Also validates string theory and in essence implies the universe was built to maintain humanoid life)
Also, an objects gravity is relative to it's energy divided by it's mass.
All credit is due to God.
what this says is the earth's mass times it's gravity squared divided by the mass of the average human times planc's length equals the gravitational constant
thanks, waiting for feedback
