Is Time Dilation Just a Clock Issue Afterall???

- Quite recently channel @dialectphilosophy released a video about time dilation showing all the phenomena of special relativity (including the twin paradox) using a sound analogy of a typical light clock. All the phenomena of SR were replicated while preserving a privileged frame of reference namely air.
So is time dilation in SR just a clock issue or is time dilation a real fundamental effect of nature?
In this video, I will propose arguments about what makes special relativity different from this sound wave analogy and how it deviates in a way that can be experimentally proven.

Since I am kinda busy I can't answer more elaborate questions in the comments but for this purpose, I created a possibility to ask questions for a small fee of 5 dollars on

Einstein once famously said, there is no such thing as time...just clocks.
A clock issue seems to me (and always has) to make much more sense than an actual time dilation
Two Words : General Relativity.
I guess oversimplistic RUclips video titles are the norm anymore.
C, is the speed of light in a vacuum. To recreate the experiment the speakers should not have been open to the air.
This is way too much complicated for me to understand. Nonetheless, I'd review the video like multiple times, and slowing down the difficult parts. Many thanks for the video.
Very nicely done video. Should convince the reasonable naysayers. Next up… convince the flat Earther’s out planet is nearly round.
So, this is why our solar system looks like a pizza?
The reason why a moving clock seems to run a little slower than a stationary one is because in order to move it you need to apply a constant FORCE to it. That force pushes the clock forward, while generating an equal and opposite force inside it, which pulls its atoms and compresses them together in the opposite direction of movement (like balls inside a car that fly toward the back of the car when it is accelerating hard). This causes the quartz crystals to contract, and therefore to vibrate at a slightly lower rate. Hence, the clock will show a slightly delayed time. But that does not mean that time dilates. It simply means that the clocks vibrating frequency changes. A similar effect happens in space, because of extreme temperature variation. The frequency of the atomic clocks is influenced by centrifugal forces and other factors such as temperature, pressure etc.
We write "after all" as two words.
Hey, sorry we're late to the party here -- but thanks a dozen for providing such a great and nuanced breakdown of this topic! Again, we find your style of presentation very straightforward and easy-to-follow, and your enjoyment in teaching and debating these sorts of topics really translates to enjoyment for the viewer. We immensely appreciated your discussion of the relation between atomic clocks and light clocks, as many people were confused about how these can be the same thing, and the deeper dive into the Doppler effect and what it means to "see" other clocks ticking was illuminating as well.
1. Relativity was never “proven”.
Your video and the comments section (not Dialect's one) make me rethink that time dilation could be an effect of "clock", the electromagnetic one. As you pointed out in the end of your video, muon decay is the proof of time dilation that we are using for a long time, but if the "clocks" in the muons are also affected by the electromagnetic force, then things may turn out to be just clock issue.
THANK YOU - I found that "sound clock" thing on Dialect quite odd too. Nothing in a sound based system has velocities sufficiently high to bring in relativistic effects.
This video is the first one I've seen from you and I was losing my mind at the arguments you made in the first half😂. I'm very glad I stuck until the end
Liked how you pointed out the flaw in the light clock metaphor by making the "clock" run in the direction of motion rather than orthogonal to it. I think the metaphor can be saved (and adequately distinguished from a sound clock) by extending it to 4 dimensions. From the moving clock's own perspective it's always oriented in its "time" dimension which is always orthogonal to any spatial dimension. In other words unlike a sound clock you can never orient the "clock" in a different direction besides proper time, nor can you "block" the medium with a physical barrier because the medium - the electromagnetic field in this case - itself exists in 4 dimensions.
As for muons, their decay is mediated by the weak force. Whatever causes time dilation, whether it be Minkowski spacetime or dialect's explanation, it presumably affects all of the forces in the same way. The way I understand this when I think of Dialect's interpretation is that I think of all of the particles and all of the interactions as being made out of, at the deepest base level, massless particles moving at the speed of light.
The glint in your eyes as you step us through all this (in my case, for the first solid review in nearly a half century), is wonderful. Al the while, I'm thinking "What a glorious guided tour to Michelson-Morley."
I think this channel and dialectphilosophy should have a debate or do like an hour long collaboration.
Do doppler effect apply to a remote clock speed or just to the frequency of electromagnetic signals sent from moving objects?
