SUMMARY

The discussion centers on the concept of stopping time, primarily through the lens of Einstein's theory of relativity. Participants agree that time appears to stop at the speed of light, but emphasize that this is a relative observation; an observer traveling at light speed would not experience time stopping in their own frame. The conversation also touches on the implications of infinite energy required to reach light speed and the effects of gravitational fields on time dilation, particularly near black holes. Overall, the consensus is that while time can appear to stop from certain perspectives, it cannot be stopped in an absolute sense according to current physics.

PREREQUISITES
  • Understanding of Einstein's theory of relativity
  • Familiarity with the concept of time dilation
  • Basic knowledge of energy-mass equivalence (E=mc²)
  • Awareness of gravitational effects on time
NEXT STEPS
  • Explore the implications of time dilation in General Relativity
  • Study the concept of event horizons in black holes
  • Research the theoretical existence of tachyons and their properties
  • Investigate the relationship between speed, time, and energy in relativistic physics
USEFUL FOR

Physicists, students of theoretical physics, and anyone interested in the complexities of time and relativity will benefit from this discussion.

Light traveling faster than light! Imarinary relavistic mass. These are tachyons! I don't think they exist, but who am I to challenge you know whom.
Won't it wonderful if we can create tachyons and harness (use) them. We can see the past! And much more!

Even starting with the idea of a tachyon, it still won't let you communicate backwards in time! The laws conspire against it, even with that handicap! See http://math.ucr.edu/home/baez/physics/ParticleAndNuclear/tachyons.html" .

If you stopped time in your own reference frame, how would you know it?

Even if you could stop time how would you ever know? Nothing would happen. It would start again and you would never know it had stopped.
