| Feb 28, 2023 at 19:09 | comment | added | Poisson Aerohead | By using CGS, you have removed one of the factors, but you still have G. You would need to rescale so the G is also 1. Also, the Gmm/d^2 is in mks, so your ratio still is apples to oranges. To do this properly, you need to take both equations in the same units (say mks) and then scale the units until the form of the equation is the same (either 4pi in both denominators or neither and no arbitrary factors). You then have a meaningful "charge to mass" ratio. See the variety of natural units en.wikipedia.org/wiki/Natural_units | |

| Feb 28, 2023 at 3:39 | comment | added | Poisson Aerohead | As I like to say, the real question is not "why is gravity so weak" but rather "why are things so light" in my opinion. The charges, masses, and factors are just a matter of units. If you set units so that both Coulumb's law and Newton's gravity law have exactly the same form everything but charge and mass cancels. Clearly those force ratios will be the same, so it will be caused by the charge to mass ratio only. The question then is, why are electrons, and even protons, so light, or so charged, or just why is that ratio so high. | |
