The poster is into pseudo-science. Don't get all serious about it.
How do you get away from gravitational force? Simple, get a greater force in the opposite direction.
P.S. Even light (non-matter) bends under gravitational force of black holes.
The typical science fiction answer is trying to travel in fifth-dimension, i.e. wormhole, theroactically.
As gravitational force is creating a curvature in space, it may be possible for two different space-time to touch on itself (like folding paper to a point when two different point on paer touch). There, we can space jump, in theory.
