We live in a bubble. Seriously.

Of the four fundamental forces, strong force, weak force, and electromagnetic force are attractive and repulsive.  Gravity is only attractive, or so we think, as it is very difficult to measure the effect of gravity over long distances.

 

I have an odd feeling Gravity might be both too. Think about it, jsut in our solar system each planet and the sun have gravity. If the planets didnt have their own gravity I believe that the planets would have been absorbed into the sun. Think of it as friction of sorts. Spin two balls, think of the air circulating around it as a defensive repulsive force. The air circulating protects the spinning balls to a point. Gravity is similar. It rubs against one another protecting whats contained in the range of gravity. The strong a planet's gravitational force the closer to the sun the planet can be. Of course gravity might be able to be eaten away by stronger gravitational and magnetic forces.

This is my theory anyways.

 

It's a very sound theory, but the bolded part presents a problem. When it comes down to gravity, there is no difference between the planets and the sun, just their mass. Thus given your scenario the Sun would have to lack gravity as well thus the whole hypothetical example falls apart. Though the rest seems interesting.
