About the Lorentz invariance of Planck constant

In summary, the Theory of Relativity states that Planck's constant is the same in any inertial frame, and while there is no single experiment to prove this, the fact that Special Relativity has been tested and proven in various cases supports this concept. However, there has not been any experimental evidence in a spaceship traveling at near the speed of light.

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?

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.

Related to About the Lorentz invariance of Planck constant

1. What is the Lorentz invariance of Planck constant?

The Lorentz invariance of Planck constant refers to the fact that the value of the Planck constant, denoted as h, remains the same in all inertial reference frames according to the principles of special relativity. This means that the value of h does not change when an observer moves at a constant velocity, regardless of their frame of reference.

2. Why is the Lorentz invariance of Planck constant important?

The Lorentz invariance of Planck constant is important because it is a fundamental principle of physics that plays a crucial role in our understanding of the universe. It allows us to make accurate predictions and calculations in various fields of physics, including quantum mechanics and relativity.

3. How does the Lorentz invariance of Planck constant relate to special relativity?

The Lorentz invariance of Planck constant is a consequence of the principles of special relativity, which state that the laws of physics should be the same for all inertial observers. This means that the value of h should not change for observers in different frames of reference, and thus, it is considered to be a Lorentz invariant quantity.

4. Can the Lorentz invariance of Planck constant be violated?

No, the Lorentz invariance of Planck constant is a fundamental principle of physics that has been extensively tested and has not been found to be violated. However, some theories, such as loop quantum gravity, propose modifications to the Planck constant that could potentially affect its Lorentz invariance at very small scales.

5. How is the Lorentz invariance of Planck constant measured?

The Lorentz invariance of Planck constant is not directly measured, but it is confirmed through various experiments and observations in physics. For example, the accuracy of the predictions made by quantum mechanics and special relativity, which rely on the Lorentz invariance of h, have been extensively tested and confirmed through experiments such as the double-slit experiment and the Michelson-Morley experiment.
