Discussion Overview
The discussion revolves around the behavior of planetoids that experience complete fractures, specifically focusing on the role of gravity in maintaining their spheroidal shape and the potential for these fractures to repair over time. The scope includes theoretical considerations and speculative reasoning about geological processes and physical forces affecting planetoids.
Discussion Character
- Exploratory
- Conceptual clarification
- Debate/contested
Main Points Raised
- Some participants suggest that gravity may help maintain the spheroidal integrity of a planetoid, while others propose that it might not repair fractures, depending on various factors.
- One participant notes that rubble could fill fractures in smaller, irregularly shaped planetoids, while larger ones might erode features back into a spherical shape.
- Another viewpoint raises the possibility that tidal forces could contribute to both the creation of fractures and their eventual fusion, although the presence of catastrophic cracks held together by gravity is also mentioned.
- A later reply emphasizes that if the fractured pieces remain gravitationally bound, geological processes could lead to the eventual disappearance of the fracture, contingent on the momentum and kinetic energy of the fragments.
Areas of Agreement / Disagreement
Participants express differing views on the mechanisms by which gravity interacts with fractures in planetoids, and there is no consensus on how often gravity might repair fractures or maintain spheroidal integrity.
Contextual Notes
The discussion includes assumptions about the size and shape of planetoids, the effects of geological processes, and the influence of tidal forces, which remain unresolved and may affect the conclusions drawn.
