the gravity of a black hole or the gravity of lpanet earth doesnt work the same

the gravity of a black hole is the same of a vacuum cleaner.
the attraction is bigger to bodies of lower mass
and in the earths gravity it attrats faster the bodies of larger mass
so vacuum and gravity isnt the same as i had said before, its the
inverse

void-mass=1/(mg)

mass*g(void-mass)=1
g(void*mass-mass^2)=1
