L’universo è una cipolla cosmica:tra galassie, quantistica e multiverso | Riccardo Azzali | TEDxBari

Quick Overview

Riccardo Azzali, a theoretical physicist, uses the analogy of a cosmic onion, where each layer represents different scales of reality—from the Plank length up to the observable universe—to explain that the fundamental constituents of matter and consciousness are deeply interconnected, suggesting that both are built from the same fundamental void, which challenges conventional scientific assumptions about separateness.

Key Points: Riccardo Azzali, a theoretical physicist, presents the concept of reality as a "cosmic onion" with layers ranging from the Plank length (10^-35 meters) up to the size of the observable universe (94 billion light-years in diameter). The speaker highlights that the 99.999...% void in both atoms (electrons orbiting a nucleus) and the universe (galaxies scattered in space) is a profound structural similarity. He argues that the fundamental constituents of matter (atoms, molecules) and consciousness are both derived from this fundamental void, challenging the idea of inherent separation between the physical and the mental. Azzali relates the structure of the universe (galaxies, stars) to the structure within a cell (molecules, atoms), emphasizing that complex structures emerge from simple rules. He introduces the concept of the universe having a diameter of 94 billion light-years and the Plank length being 1.6 x 10^-35 meters to illustrate the vast scale differences. The talk suggests that the laws governing the microscopic quantum world might also govern the macroscopic world and even consciousness, implying a unified reality. The speaker finds the analogy of the universe being almost entirely empty (99.999...% void) to be the most striking connection between the cosmic and the subatomic.

Context: Riccardo Azzali delivers a TEDx talk titled "L’universo è una cipolla cosmica" (The universe is a cosmic onion) at TEDxBari, exploring the parallels between the structure of the physical universe and the structure of matter at the subatomic level. Azzali, identifying himself as a theoretical physicist, uses this extended analogy to bridge the gap between the infinitesimally small (quantum mechanics) and the overwhelmingly large (cosmology), suggesting a unified underlying principle for existence, consciousness, and physical laws.
