The four fundamental forces are equal in their magnitude in terms of effect caused by them in their particular realm. Space time realm perceived by us is hence not the perfect realm due to imbalance of magnitudes of fundamental forces. Hence the force field emanating from source particles in one realm do cross the space time realm known to us and interact with the other realms too. String theory proposes that force of gravity is weak in the dimensions known to us the unmeasured parts transcends into other dimensions. Same goes for all four fundamental forces these forces form as many realms as many permutation and combinations are possible away from the perfect equilibrium where all forces keep all matter, energy, space and time intact and bound.Saying so, there exists a plane of dimension where gravitational forces take precedence over electro-magnetic forces, and the atomic theory in that plane would indeed take sun and planet model, while quantum states would define position of massively heavy charged bodies separated far away from each other. In still other dimension, the strong nuclear force would be an extremely weak interacting force holding galaxies together by continuously exchanging states and inter-converting identities.If that were true, black holes would simply mean a portal to another dimension where our conventional laws of physics are not valid, and speed of light, the gravitational constant would all take a different magnitude. Essentially, black hole is just one way for this realm to attain equilibrium for weaker force of gravity, and the possibility of small black holes forming on hadron collision is really a possibility because the imbalance of forces in this dimension can only be dissipated through tearing apart the very fabric of space time and through to the other optimum dimension.
