Penrose Interpretation and Quantum Gravity

Developed over many decades, quantum mechanics began as a series of controversial mathematical explanations of those experiments that were unsolvable for classical physics. Multiple scientists contributed to its foundation between 1900 and 1930, and it has gradually gained acceptance and experimental verification. The utility of this theory is based entirely upon its ability to predict and explain experimental results, which it does phenomenally well. Nonetheless, the wonder about what kind of world quantum mechanics describes is still controversial, and there is truly little agreement among physicists about what the world is like according to this theory. In recent decades there have been authors who have explored the relationship between interpretation debate and quantum gravity—among them, Roger Penrose.

Initially attracted by his interest in the emerging black hole information paradox, Penrose embarked on the question of quantum measurement. He proposed that a quantum state remains in superposition until the difference of space-time curvature attains a significant level. Drawing on historical records, scientific papers and conferences, my aim in this project is to elucidate what led Penrose to raise these ideas.
