I have a poor physics book that doesn't really explain things easy. My book states that Strong force - 1 Electromagnetic force - 10^-2 Weak force - 10^-6 Gravity - 10^-43 This is the "relative strength between the 4 forces" is what my book says. But what does that mean? Is there some maximum amount of gravity, which always is lower than the maximum amount of strong force. (it might be a very stupid question) ?
