Gravitational attraction is theorized to extend infinitely, with its effects diminishing as distance increases, according to both Newton's and Einstein's theories. This raises the question of whether there is a point in spacetime where gravitational influence ceases entirely. The discussion suggests that while flat spacetime is a useful conceptual tool, true empty space does not exist, as all regions are influenced by gravitational forces. It is proposed that there may be locations where the net gravitational forces balance to zero, but no area is completely free from gravitational effects. Ultimately, spacetime is always warped to some degree due to the presence of mass.
