Suppose, a ball is thrown upwards. The proper time interval between the throw and the instant at which it attains max height is t. And, the dilated time interval between the same events for a different moving observer is 2t. Now, my question is: Both observers see the same instants happening, then what accounts for the increased time for the later observer? Do the same instant remains paused for the second observer for twice the time length than the first observer? Suppose for the first observer the height of the ball above the ground at time T is 2m and after time dt, it is 2+dx m. By an increase of dt, just the next instant happens and nothing happens in between. Now, for the second observer, the ball remains paused at the height of 2m for a time interval 2dt. So, the universe just makes time 'more chunky' to account for the increased time. Just like when we slow down a movie, the time between two scenes gets dilated, but we still don't see what happens between the individual frames. We still see the same frames, but each frame remains paused for a longer time on the screen. So, does the second observer see what happens to the ball between the time T and T+dt to add up to the original no. of instants to make more instants ( hence more time ) or does the same instant at time T remain paused for a longer time 2dt to account for the increased time?
