That is nonsense, because the influence of gravity is present and significant throughout theUniverse, and especially within the Solar system and the Milky Way Galaxy. Zero gravity is so named not because there is no or little gravity, but is so-caled because the balance between the gravitational accelerations and other inertial forces are balanced to result in a freefall and net zero gravity equivalent as if there were zero gravity.
No offense, but are you a female???
