SUMMARY

Closed Timelike Curves (CTCs) are theoretical constructs in General Relativity that do not violate causality, yet none have been observed in reality. The discussion emphasizes that while there is a body of literature on CTC solutions, such as the source provided from arXiv (1206.5485), the existence of these curves remains purely speculative. Participants are discouraged from inquiring about their existence, as it has been established that CTCs have no known bearing on reality.

PREREQUISITES
  • Understanding of General Relativity (GR)
  • Familiarity with the concept of causality in physics
  • Knowledge of theoretical physics terminology
  • Ability to interpret academic literature, particularly in theoretical physics
NEXT STEPS
  • Research the implications of Closed Timelike Curves in General Relativity
  • Explore the arXiv paper titled "Closed Timelike Curves in General Relativity" (arXiv:1206.5485)
  • Study the concept of causality and its significance in theoretical physics
  • Investigate other theoretical constructs in physics that challenge our understanding of time
USEFUL FOR

Theoretical physicists, students of General Relativity, and anyone interested in the philosophical implications of time travel and causality in physics.

These are apparently Closed Timelike Curves that don't violate causality, do they exist?

Can you describe what they are better? Or provide a source that discusses them? I've never heard of this terminology.

Only big thing I could find on them.

None have been observed.
 
I see these threads from QuestionGuy over and over and over and wonder if I am in a closed timelike curve!

@TheQuestionGuy14 V50 is right, this is quite tiresome. If you have questions about the theoretical literature on closed timelike curves then you are welcome to post them here. There is a body of literature on the theory of CTC solutions to GR.

However please stop asking any questions related to their existence. No such curves have been observed, they are purely theoretical. They have no known bearing on reality.

Further posts on CTC existence or reality will be summarily deleted. Thread closed
