Hi, I think this question goes here... My question is about time. I have seen some documentaries and read some articles in the past but I still don't get it. Which is the time that is being measured when articles speak about space-time? Which devices are used to measure time? As almost everyone does, I carry a watch on my wrist, which is a mechanical device. If we could stop time, my intuition says that my watch will continue to work because we humans give the watch the meaning of being a instrument of measuring time, right? I don't understand the theoretical concept and the relationship between the time of space-time and the time we measure ourselves here on earth :( Does someone have a good link for dummies on this subject? I will be thankful! :) Thank you!
