lebron LaBombetta Cosmica ™️👽 Witsit RMH at altitude Because gravity bends spacetime, and gamma rays redshifting means time dilation took place. So time runs at different rates depending how close you are to a gravitational field, and GR predicts just how large this effect is. Experiment confirms it.

Your Mom, Dave LaBombetta Cosmica ™️👽 Witsit RMH at altitude Concept do not bend. Much less by a fictional force. I was reading a bit more about Muons, and it seems there is still a lot of disagreement on its nature.

lebron LaBombetta Cosmica ™️👽 Witsit RMH at altitude 'Concepts do not bend' - now you just said it again. The OBSERVATION is that time slows down in direct proximity to mass. It all happens in accordance to natural laws predicted by general relativity. That's what you can't account for; GR has predictive power.

lebron LaBombetta Cosmica ™️👽 Witsit RMH at altitude Anyway, so you don't accept gravity because who knows. And you don't accept subatomic particles because who knows. So next up is the Hafele-Keating Experiment (1971). They took an atomic clock on a plane ride, and time was dilated with velocity, again in accordance with GR.

Your Mom, Dave LaBombetta Cosmica ™️👽 Witsit RMH at altitude The velocity of the plane had an impact on the mechanism of the clock, not time. Clocks are not time.

lebron LaBombetta Cosmica ™️👽 Witsit RMH at altitude Nope. That's why we use atomic clocks. It uses the frequency of electromagnetic radiation (again, light like you agreed is real) as a stable reference for time measurement.

So it's the effect of velocity on time - not the mechanics of the clock.

Your Mom, Dave LaBombetta Cosmica ™️👽 Witsit RMH at altitude Of course the effect is on the mechanism. Else no one would have noticed it. People do not observe time.

lebron LaBombetta Cosmica ™️👽 Witsit RMH at altitude No, it's not affecting the mechanism. It slows down time.

An example of velocity affecting the time keeping mechanism would be if you had a spring loaded clock, and the acceleration imparts inertia on the spring, slowing down the indicator.

That's not what this is.

lebron LaBombetta Cosmica ™️👽 Witsit RMH at altitude What an Atomic clock is, is a clock whose reference for time measurement is the frequency of electromagnetic radiation emitted from cesium-133 atoms. This frequency is bound by the speed of light - or more accurately - the speed of causality.

Your Mom, Dave LaBombetta Cosmica ™️👽 Witsit RMH at altitude so it is a real thing

lebron LaBombetta Cosmica ™️👽 Witsit RMH at altitude Yes. Here's the one used in that first Hafele-Keating experiment.
