The Spell of Quantisation = Crisis of Modern Physics

The fundamental difference between modern physics in the form of Quantum Mechanics QM and classical physics in the form of Continuum Mechanics, is something named 

• Quantisation. 

After a long discussion with chatGPT the following conclusion as "Honest Summary" is reached:

• Quantisation means: interactions are granular, in units of Planck's constant $h$.
• It is detected physically through indivisible events (photoelectrons, Compton recoils, detector clicks).
• It is explained mathematically by replacing classical observables with operators whose spectra are discrete.
• But the mechanical reason why nature enforces this is not known. 
• It is a foundational mystery.

On the way we have learned that what Quantisation is not:

• Not simply probabilistic interpretation of wave function. 
• Not simply discrete spectrum of a continuous vibrating string/atom.
• Not simply discreteness of electron unit charge.
• Not discrete "light particles/photons".
• Not discrete "lumps of energy".  
• Not really QM but rather Quantum Field Theory for continuous fields with discrete excitations. 

But not really anything concrete beyond formalism mystery of what Quantisation is. 

The trouble with Quantisation is that it forces a split between classical continuum physics and modern quantised physics which prevents a unification of macroscopic physics of gravitation with microscopic physics of atoms including electromagnetics. 

Without knowing what Quantisation is, it is very difficult to check if the split with continuum physics is really necessary. 

The fact that modern physics has not been able to form a Unified Field Theory UFT represents a monumental failure, which is now causing a deep credibility crisis of theoretical physics. 

Modern physics is thus confronted with the following spell:

1. Quantisation is necessary.
2. Quantisation prevents a UFT.
3. Lack of UFT is the root cause to the present deep crisis of theoretical physics.
4. Quantisation is a mystery.

But based on 4. it is natural to ask if 1. is true? 

To question 1. requires a QM without Quantisation and there is a candidate for such a thing in the form of Real Quantum Mechanics RealQM which has the form of classical continuum mechanics and so allows unification. 

With RealQM the spell of Quantisation evaporates and a UFT appears as a real possibility to explore. Want to try it? 

Recall that the 1. is the leading idea today of professional physicists: The only way forward towards unification is quantising gravitation, and the only hope went to String Theory emerging 50 years ago, but this hope is now quickly eroding. No hope any more for quantising gravity. 

The only way forward is to dequantise QM. This is what RealQM offers.
