is anyone aware of evidence (preferably experimental evidence) in support of time dilation. in other words proof that it actually occurs. that is, experiments other than the one of Hafele and Keating.
i just need a starting point for some research.. just a name or the title of an experiment would be greatly appreciated. thanks!
The slowing of clocks on satellites (which must be corrected for a gravitational effect)and the extended life of mu mesons in cosmic rays has been verified.

thankyou!
i just need one more now and am having a hard time..
Certainly! In addition to the Hafele-Keating experiment, which provided evidence for time dilation associated with relativistic speeds, there are several other experiments that support the existence of time dilation. Here are a few notable ones:
1. Muon Lifetime Experiment: Muons are subatomic particles that decay at a known rate. In the Earth's atmosphere, high-energy cosmic ray collisions produce muons that move at speeds close to the speed of light. Due to time dilation, the muons reach the Earth's surface before they decay, even though their average lifetime suggests that they should decay much earlier.
2. GPS Satellite Experiment: Global Positioning System (GPS) satellites use precise atomic clocks to provide accurate positioning information. These satellites orbit the Earth at high speeds, and the signals they send are received by devices on the ground. The time dilation effect in this case is crucial for the accuracy of GPS, as the clocks on the satellites experience slower time compared to clocks on the surface due to their relative motion and the Earth's gravitational field.
3. Neutrino Oscillation: Neutrinos are subatomic particles that change ("oscillate") between different types, called flavors, as they travel through space. Experiments studying neutrino oscillations have provided further evidence for time dilation, as these particle interactions are consistent with the effects of traveling at high speeds.
4. Particle Accelerator Experiments: High-energy particle accelerators, such as the Large Hadron Collider (LHC), accelerate particles to near the speed of light. These experiments involve studying the behavior of particles, including their lifetimes and decay rates, at velocities that result in observable time dilation effects.
These experiments, among others, provide empirical support for time dilation predicted by Einstein's theory of relativity. By delving into the details of these experiments, you should find a wealth of information to start your research on time dilation.
