Solving the Paradox of Self-Built Time Machines

Click For Summary
SUMMARY

The discussion centers on the paradox of self-built time machines, specifically addressing the logical inconsistencies that arise when one travels back in time to alter their own existence. The participants reference the movie "Terminator" to illustrate the complexities of time travel, particularly the scenario where John Connor sends his father back in time, raising questions about causality and existence. The central issue remains: if one can kill their past self, how could they have built the time machine in the first place? This paradox highlights the intricate relationship between time travel and existential continuity.

PREREQUISITES
  • Understanding of time travel theories
  • Familiarity with causality and paradoxes
  • Knowledge of popular culture references, specifically "Terminator"
  • Basic grasp of philosophical implications of existence
NEXT STEPS
  • Research the theories of time travel in physics, focusing on concepts like closed time loops
  • Explore philosophical discussions on causality and the grandfather paradox
  • Analyze narrative structures in time travel films, particularly "Terminator"
  • Investigate scientific theories regarding the feasibility of time travel, including wormholes and relativity
USEFUL FOR

This discussion is beneficial for philosophers, physicists, film enthusiasts, and anyone interested in the implications of time travel and its representation in media.

Suppose i build a time machine , then go back in the past & kill myself . I die the instant i kill my past , but how in the first place i built the time machine ?

The first problem is this... how to build a time machine. If you're not able to build the time machine, then the rest are non-starters.
 
This is a giant paradox which makes the movie terminator such a great movie... (assuming youve seen it) John Connor sends a man back in time to save his mom and the man ends up being his father... How could John Connor exist until he sent his "dad" back in time... basically, which came first? the chicken? or the egg?
