since time esentialy noticably slows down for the particles moving close to light speed... then velocity is a farce. becuase the idea is that velocity is position per time. but if i move close to the speed of light, time slowed down so therefor im slower. so is velocity really position per rate of time relative to the constant now?\
another. probably better question.
how does time work when it has nothing to relate to? lets say that there is a particle. and thats it.. nothing else in the universe. at all.. empty void of nothing besides this particle. its a really small particle too... its practicaly just a point... if that point were to move. at any velocity... since it has nothing to campare to then one can't really tell weither it is moving. there is the feeling of acceleration but one can't tell weither its a positive or negative acceleration... it might have been speeding up in one direction, or slowing down in the opposite direction....
since there is nothing to gauge how fast it is moving.... you can derive motion easily enough.... cuase an acceleration... and you either are moving as fast as you accelerated if you were motionless before... or you were moving before and are motionless now... all other combinations result in either moving and slowing down... moving then speeding up... or moving and then reversing direction..
how does time work in any situation? there is not gauge to go by... so isn't time velocity, position, a farce in this situation? the only thing that still remains true and the same is existance.
