4/26    Why when we travel close to speed of light, time starts to slow down and
        finally stops at v=c? Why time has anything to do with our cell division
        which controls our aging which also stops at v=c?
        \_ where's tom? ask ilyas about the stars....
        \_ why don't you talk to that guy who always hangs around leconte
           putting up posters about his "mono-pole" magnet?
           he'll answer all your questions.
        \_ time slows down for the other guys.
           \_ No, the rest of the world speeds up, you don't slow down.
        \_ go away.  Really.

        \_ For starter: when you "travel close to c", the speed of light with
           respect to you is still c.  At the same moment the speed of the same
           instance of light w.r.t. another person who is "stationary" is
           also c.  I vaguely remember that this strange observation is what

           spawned Special Relativity.

           cells.
           \_ but how cells in your body know time has stopped, this is weird.
              \_ You can't tell that time has "stopped", in your frame of
                 reference everything will appear normal. An observer in
                 in an inertial frame of reference (one that is at rest or
                 moving with constant velocity with respect to you) will
                        \_ what?  no.  if that other inertial frame of
                           reference is moving with constant velocity of 0
                           with respect to you, time will appear the same
                           in both reference frames.
                           \_ There is no way to objectively determine if
                              a frame is "at rest" or if both frames were
                              in motion at some time t with velocity v.
                              Consider the train experiment. The frame of
                              of the observer viewing the train and of
                              the train itself are both moving with
                              constant velocity equal to that of the
                              earth. Although the observer viewing the
                              train considers himself at rest, he really
                              isn't at rest.
                              \_ obviously, but my point was that observers in
                                 all reference frames do not think that time
                                 has stopped for you.
                 think that time has "stopped" for you. Both of you are
                 correct because of the nature of time and space.
             \_ hi, you're dumb.
        \_ Time has not stopped for the person travelling the speed of light.
           An observer with a different frame of reference will measure time
           has stopped for the individual travelling the speed of light.
