SUMMARY

The discussion centers on the concept of faster-than-light (FTL) travel and its implications for time travel. Participants assert that moving faster than the speed of light would not only allow for forward time travel but also introduce the possibility of traveling backward in time, violating causality. A resource from Physics Guy is recommended for further understanding of these complex topics, particularly regarding causality violations associated with FTL travel.

PREREQUISITES
  • Understanding of Einstein's Theory of Relativity
  • Familiarity with the concept of causality in physics
  • Basic knowledge of time dilation
  • Awareness of faster-than-light (FTL) travel theories
NEXT STEPS
  • Read "Physics of Time Travel" to explore theoretical frameworks
  • Investigate the implications of causality violations in quantum mechanics
  • Study Einstein's Theory of Relativity in detail
  • Examine current research on FTL travel technologies
USEFUL FOR

Physics enthusiasts, students of theoretical physics, and anyone interested in the implications of time travel and FTL concepts.

Hello! My dad reckons if you moved faster than the speed of light you would travel forward in time? Am I right in thinking this is ridiculous!
 
Physics news on Phys.org
I'm sitting here on the couch hardly moving, except my fingers to type this, and I'm traveling forward in time...
 
Actually, FTL travel implies you travel backwards in time.
 
where does lightning come into this...?
