Can you define the word "measurement" as you use it? Is it subjective or objective?lec_nemanja wrote: ↑March 25th, 2023, 6:00 am I agree that time is not real. However, time measurement is real. I believe that many people unconsciously confuse these two concepts.
In various fields of physics, there are some fundamental unresolved problems include (1) the Observer Problem, and (2) the Measurement Problem.
Different observers will measure distances and times differently. Just as what is to the left in one observer's reference frame can to the right in another person's reference and neither left nor right in a third person's reference frame, what's in the past in one observer's reference from can in the future in another's. What's time in one reference frame can be space in another, or vice versa. Different observer's can measure how long something in space differently, which is called length contraction in Einstein's physics. Likewise, they can measure how long something is in time differently, which is called time dilation in Einstein's physics. Likewise, events happen can happen in a different order in different reference frames, such that event A is before event B in one observer's reference frame while event B is before A in another observer's reference frame, which is called the relativity of simultaneity in Einstein's physics.
For more on that, please see my other topic, Your left is not the left. There is no "the left". Likewise, there is no "the past" or "the future". Time is not real.
