Hi, I have been thinking about the philosophical implications of time and have in the process been analyzing the consequences of time as conceived of by special relativity. I have a couple of questions though, and I would really appreciate it if someone could offer their knowledge in an attempt to answer them: 1. How does time emerge in special relativity? Could we conceive as time as simply measuring the duration of a process? i2. In an inertial reference frame, if two particles are at rest with respect to each other, is time passing for them? Any insights on these questions would be very welcome indeed. Thanks!
