Are time dilation experiments conclusive?

Click For Summary
The discussion centers on the concept of time dilation as described by the theory of relativity, emphasizing that time is a measure of change relative to other changes. It explains that while time appears to slow down for a fast-moving object from an observer's perspective, both the moving object and the observer experience time at the same rate locally. Experiments, such as those comparing atomic clocks on Earth and in orbit, provide evidence for time dilation, but there are questions about whether these findings can be generalized to complex systems like living organisms. The conversation also highlights the importance of reproducibility in experiments to support the conclusions drawn about time dilation. Overall, the evidence for time dilation is considered sufficient, but the nuances of its implications continue to spark debate.

I assumed that you knew that, my point was that your statement, sans caveat, might be confusing to less informed members reading your post.

Actually, the original name was the Global Positioning Satellite System, so GPSS used to be correct, but "GPS System" has never really been correct.
