what is tha difference between

None, of course, I was just emphasising that it is a *real* difference ..
not just some sort of optical illusion, or an error in the ticking of a
clock.
thanks, so if clock is good, he becomes
really older for no reason

And how did you conclude that nonsense from what I said? No wonder you have
problems with physics .. you can't even comprehend written language, let
alone the mathematics and logic involved.

you said clock no error, but he really gets older


In the so-called twins paradox, the travelling twin has experienced less
elapsed time because its path through space-time (which involves changes

how would you know about others experiences

in
frame of reference) is different to that of the stay-at-home twin. One can
say that more simply: the stay at home twin is older than the travelling
twin.

why, entropy goes faster staying home?
