Discussion Overview
The discussion revolves around the possibility of a single super-massive black hole being visible in two different locations in the universe. Participants explore theoretical implications, gravitational effects, and the role of phenomena like gravitational lensing, while considering the nature of space and gravity.
Discussion Character
- Exploratory
- Debate/contested
- Conceptual clarification
Main Points Raised
- Some participants propose that while it is theoretically possible for a super-massive black hole to appear in two locations due to cosmic topologies, no observational evidence currently supports this, suggesting the universe's size is larger than what is visible.
- Others argue that gravitational lensing allows for the same astronomical objects to be observed in multiple locations, indicating that this phenomenon can create multiple images of the same black hole.
- A participant questions the effects of very large gravity on the fabric of space, suggesting that if space were curved sufficiently, it might create a pull on separate sections of the universe, though this is not predicted by regular General Relativity.
- Another participant mentions that higher-dimensional theories might allow gravity to travel between folds in space, but emphasizes the lack of observational evidence for such claims.
- Some contributions reflect skepticism about the feasibility of knowing whether such phenomena occur, likening the discussion to science fiction.
Areas of Agreement / Disagreement
Participants express differing views on the possibility of a super-massive black hole being visible in multiple locations, with some supporting the idea through gravitational lensing and others questioning the implications of large gravitational effects on space. The discussion remains unresolved regarding the broader implications of these phenomena.
Contextual Notes
Limitations include the dependence on theoretical models, the lack of observational evidence for certain claims, and the unresolved nature of how gravity interacts with the fabric of space in higher dimensions.
