Einstein's light clock is retarded

 Einstein’s immaginary light clock was based on two mirrors and a light pulse which reflected between them, and then he made the light follow the moving mirrors in a diagonal for no reason which implies that light somehow inherits the horizontal speed of the mirrors, which is wrong and doesnt happen with waves, but only with particles or objects like balls. That made the traveled distance between each reflection longer, causing the moving clock to tick at a different rate, but thats only because his crackpot imagination illogically FORCED the light wave to follow the moving mirrors.

Indeed, the way in which Einstein derrived length contraction and time dilation is illogical and pseudo-scientific because its based on an immaginary experiment where he imagined a light clock which doesnt actually exist, and which does whatever Einstein’s imagination wanted it to, like the light wave following the moving mirrors and moving diagonally on a longer path so that it could reflect between the mirrors as the immaginary clock is moving. That is physically impossible, because waves do not inherit the speed of their source, so a light pulse emmited perpendiculary to the mirrors would not gain the horizontal speed of the clock and will simply miss the moving mirrors and Einstein’s light clock would stop working. His whole demonstration is a metaphysical non-sense, since it is entirely based on his crackpot imagination and not on a real physical phenomenon or experiment.

There’s a good reason why no one has ever built a light clock by using Einstein’s imaginary design and ‘physics’. Because light WAVES do not behave like BALLS, except in Einstein's imagination. A REAL light wave does not follow the moving mirrors because it doesnt inherit the horizontal speed of the mirrors like a ball, it remains behind them and simply MISSES them.

Only if the light beam is oriented at a specific angle in the clocks frame it could reflect of the moving mirrors of the light clock as they travel at relativistic speeds (as per Einstein’s thought experiment). But if it is oriented perpendiculary to the mirrors, it will simply remain behind them and miss the mirrors. In Einsteins thought experiment the beam is perpendicular to the mirrors in the frame of the moving clock, and he imagines the same beam takes a diagonal path in the frame of the observer at rest, so that he agrees with the moving clock’s frame that the light hits the mirrors. But that only works with particles or objects like BALLS, because they inherit the horizontal speed of the source ! And that transformation works because the speed of the ball composes with the speed of the clock, and you get a diagonal speed vector using Pythagoras theorem for the non moving observer. But the speed of the wave does not compose with the speed of the source, so it is illogical to expect the light wave to take a diagonal path in the non moving frame, while moving at the same speed c in both frames. It is only because he treats light as a particle and illogically imagines that the light wave will inherit the horizontal speed of the clock like a ball, that the path of the light beam increases in his imagination, causing light to travel that longer path in a longer time, and therefore concluding that time dillates for the non moving observer compared to a comoving clock observer. Because his light clock thought experiment is a mix up of wave and particle physics which is completelly illogical and absurd, like a metaphysical word salad.

Regarding the second postulate, I think it is physically correct but completelly unnecessary because in classical physics waves have a preffered frame, which is the rest frame of their medium, so postulating that ‘the speed of light is constant for all moving observers’ is not necessary because it follows from light being a wave in a medium which is its preferred frame of reference, therefore being independent and completelly disconnected from any other frames. All experiments show that light is a wave and its speed does not depend on any other frames, but only to its own preffered frame- which is the AETHER. Because the speed of light waves only depends on the properties of its medium, like electric permitivity and magnetic permeability ! And the fact that the observer is moving does nothing to change those properties.

Just like the speed of sound does not depend on any observer, it only depends on the properties of its medium of propagation. The moving observer only measures a different apparent frequency and wavelength, not a different speed of sound. When you multiply observed frequency and observed wavelength you get the speed of sound in the medium. Same goes for light. So all observers agree that the speed of light is constant:
