About the Lorentz invariance of Planck constant

Click For Summary
SUMMARY

The invariance of the Planck constant across different inertial frames is supported by the principles of Special Relativity, which asserts that physical constants remain unchanged regardless of the observer's motion. While no single experiment definitively proves this invariance, the consistent success of Special Relativity in various tests implies that the Planck constant does not vary with the motion of the observer. Notably, the Planck constant has shown no seasonal variation, indicating its stability across different inertial frames.

Is it proved experimentally that the Planck constant is invariant in the moving system?
If that experiment exists, would you show me that in detail?
 
Physics news on Phys.org
Theory of Relativity (Special - I assume you're not asking about General Relativity here) says Planck's constant is the same in any inertial frame.

There isn't just a single experiment to cover this, rather the fact that SR works in all cases tested so far.

Admittedly many important cases haven't been tested; for instance, no one's actually done experiments in a spaceship going near speed of light.

Perhaps if you expand on your question a more satisfactory answer would be possible.

The value of Planck's constant has never been observed to change with the seasons, even though every physics lab on Earth is at rest in a completely different inertial frame in June and in December.
