Scientists are puzzled how such small objects can have control over other immensely huge ones (in astronomical terms, of course), because of the contrast between black holes (which are neither holes nor black, but regions in space-time) in relation to their respective galaxies (they believe that each galaxy is ruled by a black hole at its center).
It seems to me that they have not read (or have forgotten) Manoel de Barros: "My poetic impulse tells me that big things must be unbalanced with small things."
