do you kinow a simple and convincing argument for the fact that proper time is a relativistic invariant?

daniel_i_l said:"Proper time" between 2 events is the time that is measured by an observer moving from event1 to event2. How could different observers disagree on what some other observer measured? (they can all measure different times between the events but they all agree on what one "chosen" observer measured)
daniel_i_l said:Also, all observers agree on the ST interval between events. the proper time is equal to this interval.

The relativistic invariance of proper time refers to the concept that the passage of time is relative and depends on the observer's frame of reference. This means that the measurement of time can vary depending on an observer's relative speed and gravitational forces.
Understanding the relativistic invariance of proper time is crucial in the field of physics, as it helps explain the behavior of objects moving at high speeds and in strong gravitational fields. It also plays a significant role in the theories of relativity and has practical applications in fields such as space travel and GPS technology.
Proper time is the time measured by an observer in a specific frame of reference, while coordinate time is the time measured by an observer in a different frame of reference. Proper time takes into account the effects of relative speed and gravitational forces, while coordinate time does not.
Yes, the effects of relativistic invariance of proper time can be observed in everyday life, although they are usually very small. For example, GPS satellites have to account for the difference in time due to their high speeds in orbit, or else they would not be accurate.
The concept of relativistic invariance of proper time has been extensively tested and verified through experiments, such as the Hafele-Keating experiment and the Pound-Rebka experiment. These experiments involve measuring the difference in time between two clocks, one on Earth and one in motion, and comparing it to the predictions of the theory of relativity.
