Gravitational force is never truly zero. If it has mass, it is pulling at you, though it may be so close to zero that you don’t realize it.

Wait, I thought gravity is not a “force” but the curvature of spacetime, so at some point the curvature gotta end or be disturbed by some other source nearby, right? A star so far away is not exerting any “force” on me as I already have two massive objects Earth and Sun twisting the spacetime around me so much. I could however be getting some gravitational waves from that star but not sure how strong they’d be or if they reach me at all (again given Sun and Earth).
