Modern Physics as Tragedy

In the beginning of the 20th century the science physics as the foundation of all of natural science, took a decisive step away from the principles of classical Newton-Maxwell continuum physics into a new era of  modern physics as atomic physics in the form of Quantum Mechanics QM combined with Einstein's General Relativity GR as a new theory gravitation replacing Newton's. 

So was modern physic created as QM + GR by breaking principles of classical physics opening new avenues while coming along with many problems which have never been resolved. 

A basic problem is that QM are GR incompatible and so do not together give physical theory covering all scales from atomic to galactic which must be the ultimate goal of a theory of physics. Something must be seriously wrong with either QM or GR. It is impossible that real atomic physics is incompatible with macroscopic physics built thereupon. 

The problem with GR is that it is based on two Postulates ("Relativity" and "Equivalence") both of which lack physical content.

Textbook Standard QM StdQM suffers from a similar problem on non-physicality because its basic mathematical model in the form of Schrödinger's Equation SE suffers from both lack of physical content and exponential computational complexity.  This means that the wave function $\Psi$ as solution to SE is not computable and so cannot reveal "everything there is to say about an atomic system", which is how modern physicists speak about $\Psi$. 

Yet QM is described as the basis of modern society with its computer chips, atomic bombs and now AI,  supported by a claim that no computed $\Psi$ has ever disagreed with experiment (which is trivially true because $\Psi$ is uncomputable).

Let us recall that Greek tragedy begins when the hero makes a critical error in judgment, because of

• hubris
• ignorance of crucial facts
• stubbornness

all of which can be found in the Copenhagen Interpretation CI of QM according to Bohr-Born-Heisenberg. 

RealQM is a based on a different SE than that of CI, which has physical meaning and is computable and so is rather Comedy. Prefer Tragedy or Comedy? Your choice.

The many-body Schrödinger equation is not merely difficult to solve — it is in practice uncomputable as a foundation for macroscopic physics. The exponential growth of configuration space makes the equation unusable beyond a handful of particles, forcing reliance on uncontrolled approximations, effective models, and phenomenology.

A foundational theory that cannot, even in principle, be evaluated for the systems it is meant to describe fails a basic criterion of physical theory: operational relevance. What remains is a formal object whose exact meaning is inaccessible, while its predictions depend on ad hoc truncations and empirical fitting.

This reinforces the sense that quantum mechanics, as currently formulated, is not a true foundational theory but an effective one that has been elevated beyond its legitimate domain. Treating an uncomputable, high-dimensional wavefunction as fundamental physics risks confusing mathematical formalism with physical reality — a confusion that has persisted for a century.
