I hope my question makes some sense; if not, just post an "evil smiley" and ignore it
So, my only "knowledge" about this is based on one of Hawking's books, wherein it is written: If space had four dimensions instead of three, gravitation would behave differently (I think it was [tex]1/{r^3} [/tex]), so that there wouldn't be any stable planet orbits any more.
Now, what would happen to the electromagnetic force? My particular worry is the Lorentz force: If there is an analogon in four dimensions, what would it's direction be? Because, in 3D it is perpendicular to velocity and field vector, but in four dimensions this is ambiguous.
Would there possibly even be more than two aspects of the electromagnetic force? Hm?
