Regarding atomic clocks and time dilation, they keep testing again and again with more and more accurate atomic clocks. Does that mean these physicists don't accept time dilation? If you want to do more clock tests, why not do diverse testing other type of clocks -- if that is not feasible...

It is not useful to study a perpetual motion machine, but it is useful to study how various properties change at high speeds, with elasticity at high speeds being one of the properties that would play a role in the tuning fork clock -- and that is a field of study, as #29 mentioned.

My statement was open and invited correction. I am not sure what neutron star rigidity and SR Time Dilation you are referring to. What served as the clock or vibration - something rigid? Please send link. Note that SR Time Dilation in celestial bodies has had unexplained failure too, see...

The issue was regarding classical rigid structure clocks where T has a well-known classical formula that depends of properties of the materials that make up the clock. Atomic clocks do not have this issue of classical formula connecting properties of materials. So while we know the T in the...

Would you kindly provide references? Thanks.

Looking at the experimental status it would seem that Special Relativity Time Dilation verification has so far been done only for muons and atomic clocks, and not for rigid structure clocks. I suppose this is because rigid structure clocks do not have the accuracy to show time dilation, at...

I am not sure that the same argument can be raised for Length contraction, because there is no L "formula" of an object, whereas we have a T formula for a clock. So you cannot say the L in the other frame must match values of some other quantities in that frame.

Do you know of any examples of T-classical changed to T-high-speed that have been achieved by such approaches? Of course, only the latter would be the actual correct formula. Also, how can you have a classical equation that describe the motions at low speed, which you then modify by such...

Yes, the Galilean velocity addition formula is approximate and has relativistic velocity addition formula as the exact. Most importantly, we are able follow the reason for that. For myriad clocks, are the known time period formulas only approximate and valid at low velocities? How do we...

You say the formula could be "only valid for clocks at rest." But should Time period of a clock and its relation to various quantities not continue to hold even in the other frame? If the T formula changes in the other frame then does that not mean that we have a violation of the laws of physics...

Agreeing with everything you said ... then, as I pointed out, using the tuning fork clock we can work out a formula connecting E and ρ for relativistic speeds. And other formulas using other clocks.

It would seem the formulas for E in "advanced papers" involve general relativity. So there is no accepted special relativity formula for E between frames that I can find. What I had noted was working out the other quantities in the formula. We also have l, A and I which are affected by Length...

You say: The better way to understand it is in terms of the actual relativistically covariant expressions. Can someone kindly work it out using these expressions? They are not working out when I do them, as detailed in my post. What are these expessions for density and elasticity? I did not...

I had tried but does not work out. Density = mass/volume. We have relativistic mass, and for relativistic volume we use the cuboid prong of the tuning fork being contracted. We also have l, A and I which are affected by Length contraction. For Elasticity value between frames there is a suggested...

Fine, but my point is that you could make myriad clocks with all sorts of T formulas, and not have a quantitative explanation of what causes the required change in the quantities T depends on by its formula, so that their values in the other frame work out to match the T in the other frame...
