The discussion centers on the relationship between gravity and atmosphere, concluding that gravity depends solely on mass and distance from the mass center, not on atmospheric conditions. Participants clarify that while gravitational force is influenced by distance, the intrinsic property of gravity is tied to mass alone. The conversation also touches on how atmospheric pressure does not compound gravitational force but rather exists as a separate force acting on objects. Ultimately, the atmosphere's presence is contingent upon the gravitational pull of a planetary body, which must have sufficient mass to retain it.

You mean something like these?JLowe said:He commented on the strength of Earth's gravity varying at different places. This is not really a density issue but a distance from the center issue. Otherwise, the strength of gravity would be weaker if you were in a boat then on land at sea level.
