SUMMARY

This discussion explores hypothetical scenarios in quantum mechanics, specifically the implications of reversing charge, time, and spatial dimensions. Participants assert that if all three aspects are reversed, the laws of physics remain unchanged due to CPT invariance. However, if only one or two aspects are altered, the outcomes may vary significantly. The conversation also touches on the limitations of predicting results in quantum mechanics without empirical testing, highlighting the philosophical implications of questioning the validity of quantum theories.

PREREQUISITES
  • Understanding of CPT invariance in quantum field theory
  • Familiarity with basic quantum mechanics principles
  • Knowledge of quantum electrodynamics (QED)
  • Conceptual grasp of the philosophical implications of scientific theories
NEXT STEPS
  • Research the principles of CPT invariance in quantum field theory
  • Explore the implications of quantum mechanics on philosophical thought
  • Study quantum electrodynamics (QED) and its experimental validations
  • Investigate the consequences of time reversal in quantum systems
USEFUL FOR

Physicists, quantum mechanics enthusiasts, philosophers of science, and anyone interested in the theoretical implications of reversing fundamental physical properties.

What would be the similarities and differences if live in a universe in which nuclei(eg proton in an H atom) have a negative charge and electrons have a positive charge? Support ideas with quantum mechanics...

Last question..what would be the consequences if time continually decreases rather than increase. Again support ideas with quantum mech/mathematics.

In the second part, are you asking what would happen if time is reversed? If so, than I say let's also switch left and right. Then we have reversed charge, time, and direction. In this case nothing will change since field theory is CPT invariant.

If you want to look at each case specifically, the processes may change depending on what you are looking at.

In summary, if we flip the charges, reverse time and space, nothing will change, but if we only do one or two of these it depends.

Technicaly this answer is correct, but a better answer would be I don't know?

If one cannot physically test an idea then one predicts the results using quantum mechanics one comes up with the answer given but what about QED no not Quantum electro Dynamics which was to be proven.

The answer is I can make a guess but I don't know wether it's right or indeed If what I'm basing my guessing on is in fact true ergo ?

Philosophy I know but what if quantum mechanics is wrong?

It at leasts bares thinking about
