The discussion centers on the relationship between gravitational acceleration and planetary surface topography, specifically exploring how gravity influences the height of mountains and the distribution of water on planetary surfaces. Participants examine theoretical implications, mathematical relationships, and geological factors affecting surface relief.
Participants express a range of views, with some agreeing on the influence of gravity on mountain height while others emphasize the complexity of geological factors. The discussion remains unresolved, with multiple competing perspectives on the relationship between gravity and surface topology.
Participants note limitations in their discussions, including assumptions about material density and the need for more rigorous mathematical formulations to support their hypotheses. Some mathematical claims are challenged, indicating a need for further exploration of the underlying concepts.
This discussion may be of interest to those studying planetary geology, astrophysics, or mathematical modeling in relation to planetary formation and surface characteristics.
billiards said:Realistically, I don't imagine planets really get that much denser than the rocky planets (although I would be excited to be shown otherwise) - so the planet would have to be very large. .
natski said:It's really a moot point anyway since it's only a side remark. What I was trying to say si that as the weight of the mantle compresses the core (i.e. the internal pressure incerases), then the gravity at the surface will also increae since the radius has increased
