In essence how does time travel relate to space?

Click For Summary

Discussion Overview

The discussion explores the theoretical relationship between time travel and space, particularly in the context of observing oneself during time travel. Participants consider the implications of faster-than-light (FTL) travel and its effects on causality.

Discussion Character

  • Exploratory, Debate/contested, Conceptual clarification

Main Points Raised

  • Some participants suggest that if time travel were possible, one could theoretically observe oneself traveling to Mars from Mars.
  • There is speculation about the existence of a "right way" to achieve time travel, though the specifics remain unclear.
  • One participant mentions the application of Lorentz transformations in the context of FTL travel, indicating that such travel could lead to arriving at a destination before departure, which raises concerns about causality.
  • Another participant questions the relationship between causality and quantum entanglement, suggesting that instantaneous effects challenge traditional notions of cause and effect.

Areas of Agreement / Disagreement

Participants express uncertainty about the mechanisms of time travel and its implications, with multiple competing views on causality and the feasibility of time travel remaining unresolved.

Contextual Notes

Limitations include assumptions about the nature of time travel, the validity of FTL travel, and the implications of quantum entanglement on causality, which are not fully explored or agreed upon.

So basically if you were on Mars, you cool look back and see yourself traveling to mars?

With the right way of time travel (if this is possible), this would be possible.
 
If we could just figure out the "right way".

I'm confused into how this theoritically would be possible?
 
I think that was mfb's point.
 
If you assume FTL travel and applied your lorentz transformations you would find that you arrived at your destination before you actually left and you can visualize this better if you plot it on a space - time diagram. It is however a violation of causality.
 
Thread locked temporarily pending Moderation...
 
isnt causality actually brought down by quantum entanglement which effect its been verified to be instantaneous happening cause and effect at the same time?
