I agree on the phenomenon of attraction, if we just look at a magnet as North attracts south. But gc1488 is also with opinion that North may attract North so does South. Love is only an abstract thing whether it is physiochemical, elctromagnetical, Magic of electron or whatever. Stylish opinion on gravity is also somewhat to be taken care of with optimum precaution because if it is the effect of gravity then it can easily lead to tragedy. I suspect, if there exists gravitational force, then it might relatively stable in comparision to gravity (so called two sided love)

So better to verify it from animal instinct perspective.
