Pardon me, I went away for the weekend. You shouldn't have PMed me as a call-out.
There are many experiments where time dilation has been shown to have happened. One common experiment is observing particles with short half-lives. Statistically speaking, if you detect that 1,000,000 muons are entering Earth's atmosphere, you can guess within a range and high levels of certainty approximately how many will arrive at a detector on Earth's surface. The half-life of a slow-moving muon (i.e. a muon in a lab setting) is 1.56 microseconds, so they knew exactly how many to expect on the Earth's surface. However, they were detecting far more muons than they expected -- well outside of that expected range. However, when you take time dilation into effect and use the speed that the muons are known to be traveling, you find that the expected number of muons detected perfectly matches what you would predict with the time dilated half life.
Or you could just use something simple like atomic clocks -- which stay accurate through use of half lives -- and show that atomic clocks which are synchronized go predictably out of synch when they move at different speeds. Like so:

the atomic clock thing is probably the most famous example of time dilation.
can we just /thread this thread.
