Hi everybody,(adsbygoogle = window.adsbygoogle || []).push({});

I'm new on this forum so I apologize in advance if I don't respect some formalities (and sorry for my English).

It is known that in the perspective of the stationary observer the events in the back and in the front of the moving spaceship are not simultaneous. If I understand well the clock in the back is advanced compared to the clock in the front. So, first you have the tick in the "back clock" and only after some time you have the same tick in the "front clock" (in the perspective of the stationary observer).

In order to have this "time shift" between the events in the front and in the back of the spaceship I expect that there is some time-dilation-rate difference while the acceleration (the "back clock" must run faster while the acceleration, in order to obtain the final post-acceleration time-shift described above).But, the SR calculations give the opposite results, and this is that the front clock runs faster while the acceleration.

What am I missing. Thanks in advance
