Roger Penrose on Quantum Mechanics and Consciousness

00:00 Introduction to Quantum Mechanics Confusion

Roger Penrose expresses his dissatisfaction with the collapse of wave functions in quantum mechanics, highlighting the confusion surrounding the Schrödinger equation. He questions the concept of measurement and observation, suggesting that these ideas complicate understanding quantum systems.

05:00 Consciousness and Wave Function Collapse

Penrose critiques the notion that consciousness collapses the wave function, arguing instead that physics, not consciousness, is responsible for this collapse. He believes both Einstein and Schrödinger viewed quantum theory as fundamentally incorrect and requires significant modifications.

10:00 The Need for Modification in Theories

The discussion shifts to the need for changes in quantum mechanics and general relativity. Penrose emphasizes that quantum mechanics needs more significant alterations than general relativity, dismissing the idea of merely quantizing gravity as insufficient.

15:00 Absurdity of Consciousness Affecting Physics

Using a hypothetical scenario about a lifeless planet, Penrose illustrates the absurdity of believing that a conscious observer impacts physical phenomena. He argues that it is the collapse of the wave function that leads to consciousness, rather than the other way around.

20:00 Microtubules and Consciousness

The conversation touches on microtubules as a potential mechanism for consciousness. Although Penrose finds the concept intriguing, he remains open to other explanations, expressing interest in recent findings related to quantum effects in microtubules.
