Spzi , 10 months ago (edited 10 months ago) There is no area or volume of zero gravity inside planets or stars. It exists as a point, but since it’s a point, it has zero size. Go in any direction from that point, no matter how little. Now more mass is behind you than in front of you; you feel gravity pulling you back. Edit: Seems I was wrong, sorry. …stackexchange.com/…/gravitational-field-intensit… en.wikipedia.org/wiki/Shell_theorem “If the body is a spherically symmetric shell (i.e., a hollow ball), no net gravitational force is exerted by the shell on any object inside, regardless of the object’s location within the shell.”
