Einstein, Bohr and the war over quantum theory
What Is Real?: The Unfinished Quest for the Meaning of Quantum Physics
All hell broke loose in physics some 90 years ago. Quantum theory emerged — partly in heated clashes between Albert Einstein and Niels Bohr. It posed a challenge to the very nature of science, and arguably continues to do so, by severely straining the relationship between theory and the nature of reality.
At the 1927 Solvay Conference in Brussels, 29 brilliant scientists gathered to discuss the fledgling quantum theory. Here, the disagreements between Bohr, Einstein and others, including Erwin Schrödinger and Louis de Broglie, came to a head.
Whereas Bohr proposed that entities (such as electrons) had only probabilities if they weren’t observed, Einstein argued that they had independent reality, prompting his famous claim that “God does not play dice with the universe”.
Suddenly, scientific realism — the idea that confirmed scientific theories roughly reflect reality — was at stake.
For Albert Einstein, reality exists regardless of the existence of the knowing subject, and from the perspective of Niels Bohr, we do not have access to the ultimate reality of the matter, unless conditioning it to the existence of an observer endowed with rationality.

The electron orbits are a "cloud".
When you observe them, you know either the momentum or location, not both.

The conventional wisdom from the late 1920s is that Bohr had beaten Einstein, and Bohr's instrumentalist version of the quantum universe prevailed over Einstein's realist approach to quantum mechanics. I even remember Bohr's Copenhagen interpretation being taught as the consensus theory in freshman physics in the 1980s.
My impression is that time has been kinder to Einstein and the Copenhagen interpretation is on the wane among researchers with expertise in quantum mechanics -- giving rise to realist interpretations of quantum reality, aka the many worlds interpretation.
Two models are correct. The Newtonian model and QM.
As I have stated, the Godel's Incompleteness Theorem states that it cannot be solved in this universe.
