Gravity

Why is gravity such a weak force compared with that of electrons circling round a nucleus. Taking the differences in size it is still a factor of thousands.

We're fortunate gravity is not much stronger than it is. If it were the Sun would be a black hole drawing The Earth and us inside and out of existence. I have weight issues as it is, thank you very much.

One explanation supports the idea of additional physical dimentions. It suggests that gravity can permeate into these physical dimensions whilst the others cannot.

However I know of no real exidence for this or proposed test

You may have touched on the problem Jake. Some say there is a 5th force which we know as dark matter. Also one paper said that gravity is 10^27 times weaker than the nuclear force of atoms so gravity must be extremely weak.

As you say if gravity was increased greatly we would have trouble putting one foot in front of the other.
