Hi, I went ahead and read through all the similar discussions and none are on this particular topic so I'll go ahead and shoot. I did find this topic as well, but my question is pretty simple. I think I understand how time dilation works, I read through the explanation here, this jives with the explanation provided in this World Science Festival panel in this video (it starts at around 11:30 if the link didn't work). This is the light clock thought experiment where it shows why a light particle in the moving clock is bouncing slower than the one in the stationary clock. This makes sense to me, and I wondered if the Hafele-Keating experiments which use a cesium beam atomic clocks work on the same basic principle described?
