Gravitational constant formula physics
Gravitational constant formula physics-Ted Jacobson discovered that gravity was related to thermodynamics However, the calculated temperature using the Boltzmann area entropy is still not reasonable We searched and discovered an empirical equation for the gravitational constant with a reasonable temperature The calculated value was 3 K, which is similar to the temperature of the cosmic microwaveElectron Gravitational Coupling Constant The coupling constant for the electron is classically derived as square of the Planck length and the fine structure constant, divided by the square of the electron's classical radius
