Could any downvoters please provide information about any actual experiment which proves existence of space-time being of different kind than existence of a number.
Also it would be nice to see any non-interpreted physical processes which involves space-time.
Literally. Not being interpreted to support or confirm a current theory.
The abstract system of two clocks and an observer is just nonsense, since the first time it was introduced by Einstein. Abstractions put together to form another abstraction with supposed properties.
Any two clocks, bring man-made devices to support an abstraction of the mind, are completely unrelated instead of measuring the same phenomena.
Time dilation is just an error of measurement and of confirmation bias.
I am still looking for an actual experiment and at least one real process.
If you don’t like clocks then the nicest earth experiment are free electron lasers. They basically rely on length contraction to create coherent light waves (you accelerate electrons until magnetic undulators are spaced at target wavelength due length contraction). You can dial whatever electron speed you want and get corresponding wavelength (although no greater than the at-rest spacing for obvious reasons) and it all perfectly matches relativistic prediction and works well/incredibly reproducible.
Where is time in this setting? Synchronization of wave length does not involve time. The device is made according the abstract, derived notion of time, same as it used the notion of a number. Nature does not posses any numbers, however. Mind of an intelligent observer does.
It is useless to argue on HN. I have literally 5 or 6 accounts banned for attacking a textbook ideas. It is easy to trace them all using HN backend.
Most of current HN crowd assume that I am some flat earth anti 5G lunatic, while I have background in philosophy, and down to earth physics way above that of downvoters.

Then don’t.

I have an A-Level in philosophy, but it’s a terrible grade and I don’t get to make up for that in philosophical discussions by waving around my Software Engineering degree.
> and down to earth physics way above that of downvoters.
That choice of phrase alone will make you look like a nut. Would you care to rephrase that, with specifics? Do you work professionally with aerodynamic simulations, for example? Or perhaps you want tell us about the video game engine whose physics model you coded?
> Time dilation as predicted by special relativity is often verified by means of particle lifetime experiments. According to special relativity, the rate of a clock C traveling between two synchronized laboratory clocks A and B, as seen by a laboratory observer, is slowed relative to the laboratory clock rates. Since any periodic process can be considered a clock, the lifetimes of unstable particles such as muons must also be affected, so that moving muons should have a longer lifetime than resting ones. A variety of experiments confirming this effect have been performed both in the atmosphere and in particle accelerators.
Though experiments are flawed in a way that a untyped logical statements may be - they mix and match abstract concepts with "concrete" ones so to speak. It is just a type error as multiplying birds by trees.
Everything which follow the famous two lighting and a train thought experiment is simply logially flawed. Full of type errors.
Time as we know it, which presumably could accelerate and what not does not objectively exist, exactly and precisely the way numbers does not exit outside one's mind. Relations are, numbers not. Processes are, time isn't.
You can refuse to call it 'time', but there's something that adjusts in an extremely predictable way that matches the relativity equations. And that something is what people are talking about. The measurements are very definitely correlated; they skew as predicted to high precision.
Do you have any objection to the output of the equations matching reality, or do you just object to how we interpret the equations? Because the former is physics, and the latter is philosophy.
If you have different physics, use it to make predictions, show those predictions are different from what the current physics says, and then do experiments to show your predictions are correct. Otherwise, you have nothing to say.
It also varies based on velocity. You can easily calculate the effect of gravity alone on a GPS satellite and it doesn't give you the right number.
But what's the difference between every physical process slowing down, versus time dilation? Unless you're arguing that somehow only clocks slow down, and not other things?
The LIGO experiment can measure the change in length of one arm compared to the other due to anisotropy in spacetime. I don't know how you could explain it without spacetime, so that sounds like non-interpreted.
Well if one tried to put a munition on target in real time (on the order of few seconds) with classical gravity calculations from 7.6km high (and while moving at a higher rate speed compared to said target), one might be surprised where it lands and less surprised when accounting for things like "time dilation".
Also it would be nice to see any non-interpreted physical processes which involves space-time.
Thank you.
