Physics Worldview Paper 6.67408 × 10-11 m3 kg-1 s-2. This number is the universal gravitational constant. It is an empirical physical constant denoted by the capitol letter G. The gravitational constant was first used in Newton’s law of universal gravitation [1] which states that any two bodies attract one another with a force which is directly proportional to the product of the two masses, and inversely proportional to the square of the radius measured between the centers of each object(F=(Gm_1 m_2)/r^2 ). [¬¬¬2] The first physical measurement of G was performed seventy one years after the death of Newton by Henry Cavendish using a torsion balance. [1] The method used by Cavendish, however, …show more content…
Many of the discrepancies are a result of deviations from Hooke’s law. [6] Two interesting aspects of the gravitational constant are the simplicity and accuracy of the equation utilizing it(F=(Gm_1 m_2)/r^2 ), and the ab
ility to inter-relate G with cosmological constant and the electromagnetic fine structure constant using the equations Λ=(2πt_e Λ_B^(1/2) =(L_P/r_e )^2) and N =〖(r_e/L_P )〗^2=〖αq〗^2/(2πGm_e^2 )≈e^(2/3α). [7,8] The factor 2 in the first equation (Newton’s law of universal gravitation) has been something that scientists have wondered at for a long time. This factor is very exact. To get a correct answer to the equation one must use precisely 2, not 1.99 or 2.001. The force of gravity has been tested over and over with sensitive torsion balances and has shown repeatedly that the factor must be precisely two up to five decimal places. Similar to the mass of a proton which cannot be changed without catastrophic results, if any value other than 2 is substituted in the equation, it would result in the eventual decay of orbits and the disintegration of the whole universe. This precision found within the gravitational law and
