we are using the concept of time;

but what is it?

and is it absoluate?

or relative?



time, is sth used to measure the progress of a process, ie, to compare two processes or to compare two different sections of one process;


if in the universe, there is only one process and a contantly proceeeding process, then we don't need the concept of time;

so, there is only one universal time; and this should be regarded as an axiom, since a formal proof seems to be pretty hard;

the relative time is a mathematical artifact;

you can use it (the relative time or different times in different whatever);

but you should not elevate it to sth divine, such as it is real.
