Can time be stopped?

[JDługosz]

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?

 

[Airman]

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.
