Well then how about since our brain is larger the electrical impulses take a longer time to travel between brain cells whereas for a fly with their equivalent of a brain and yet much smaller the travel time is so much less shorter. As a result they live in a speed-up world when compared to ours. They probable laugh at us for being slow pokes. I forgot to mention that I disagree with the speed of falling object is due to their time frame which depends on their size. Sorry about the confusion.

I think his view is plausible. Maybe from an atomic clocks' perspective their (the clock's) definition of 1-sec is one complete vibration of themselves whereas our 1-sec is a few millions (number?) vibrations of theirs.

Seems like the above shows an example where the prediction of the theory of Relativity is impossible in reality.

I appreciate your answer. When v=0 they appear to be able to synchronise to an observer on the platform and on the train. This I agree with anyone 100%. But the clocks on the train are indeed synchronised and on the platform they appear not-synchronised when v=/0. I 100% agree that when 'distance between clocks = 0' then there is no time-interval when the clocks are being synchronised no matter if the train is in motion or not. But if 'distance between clocks =/ 0' when 'v =/ 0' then the clocks won't be synchronised as observed by a ground observer. Thnaks. Have glanced through but is not related. Yes, bringing the clocks and the two observers together returns them all to the same reference frame. But what will the two clocks show? Perfect synchronisation or time-interval between the clocks?

Guys, what I am trying to say is that there seems to be something impossible (perhaps I missed something?) in the theory as applied to the clock synchronization above. The two clocks are being synchronized by using light signal. According to Relativity, both observers are correct in their observations: the observer on the train (rest frame) observes both clocks to start ticking from 0-second. The observer on the ground observes the clock in the rear end of the train to start ticking from 0-second followed by the clock in the front after a time interval. As the train comes to a stop, assuming both clocks are still separated by a distance, which observer has the correct synchronization observation (or results?) if the clocks are brought together for comparison? I mean is there still a time-interval between the two clocks? Maybe the observer on the ground is wrong?

My first post! And this is a very paradoxical problem which I am unable to make head or tail. http://galileo.phys....chronizing.html From the above link... We agree that the person on the train observes synch-clocks and on the ground observes non-synch of the two clocks. What if the train comes to a stop and the person on the train brings out the clock to let the person on the ground to have a look. Then which version of the synchronization is correct? I mean what do the two observers see? I know it is not possible for one to see a synch-clock and the other to see non-synch-clock at the same time. What gives?
