Discussion Overview
The discussion revolves around the speculative idea of using micro black holes to bend space and time for the purpose of sending messages back in time. Participants explore the implications of black holes on time travel, particularly in the context of general relativity and quantum entanglement.
Discussion Character
- Exploratory
- Debate/contested
- Conceptual clarification
Main Points Raised
- Some participants propose that micro black holes could bend space and time similarly to larger black holes.
- One participant asserts that the idea of using a micro black hole and a radio transmitter to send messages back in time is not feasible, referencing general relativity's stance on closed lightlike curves.
- Another participant challenges the notion that time travel into the past could be achieved with either micro or large black holes, stating that while time travel into the future is possible, past communication remains unfeasible.
- There is a suggestion that quantum entanglement could allow for future communication with the past, although this remains speculative.
Areas of Agreement / Disagreement
Participants express disagreement regarding the feasibility of time travel into the past using black holes, with some asserting it is impossible while others explore speculative ideas. The discussion remains unresolved on the potential of quantum entanglement for communication across time.
Contextual Notes
Limitations include the speculative nature of the discussion, dependence on interpretations of general relativity, and the unresolved status of time travel theories.
