What would happen if Planck constant decreased slightly?

Click For Summary
SUMMARY

The discussion centers on the implications of a slight decrease in the Planck constant. Participants agree that such a change would necessitate a detailed analysis of how other fundamental constants, particularly those related to vacuum and photons, would also be affected. The consensus emphasizes that without specifying the dependencies and changes of these constants, it is impossible to predict the outcomes accurately. Additionally, the speed of light must remain unchanged for the analysis to hold validity.

PREREQUISITES
  • Understanding of the Planck constant and its role in quantum mechanics.
  • Familiarity with fundamental physical constants, including the speed of light.
  • Knowledge of black body radiation and its significance in physics.
  • Basic grasp of the interdependencies of physical constants in theoretical physics.
NEXT STEPS
  • Research the implications of changes in the Planck constant on quantum mechanics.
  • Study the relationship between the Planck constant and black body radiation.
  • Explore the dependencies of fundamental constants in theoretical physics.
  • Investigate the effects of varying the speed of light on physical laws.
USEFUL FOR

Physicists, theoretical researchers, and students interested in quantum mechanics and the fundamental laws of nature.

I have speculative question.
What we would expect to see if Planck constant would become marginally smaller?

My guess is that vacuum would start to produce black body radiation. Does it seems right?

There is no way to answer that question as posed. One has to specify exactly which other constants - with different dependencies on the one you change - change and by how much.

If we do not consider matter - only vacuum and photons, would it be enough to specify that speed of light is not changed?
