Exploring the structural, statistical, and informational similarities between neural networks and the cosmic web
At this scale comparison, structural patterns show remarkable similarity in their statistical distributions and organizational principles.
Human Brain Neurons: ~100 Billion
Observable Universe Galaxies: ~100 Billion
The total number of neurons in the human brain is similar to the number of galaxies in the observable universe.
Brain Connections: ~100 Trillion
Human Brain Memory: ~2.5 Petabytes
Cosmic Web Simulation Data: ~1-10 Petabytes
This similarity suggests the information stored in a human brain is comparable in magnitude to that needed to describe the universe's large-scale structure.
Despite structural similarities, the physical scale of the brain (micrometers to centimeters) and the cosmic web (billions of light-years) differs by approximately 27 orders of magnitude.

Power spectrum analysis, which measures structural fluctuations across different scales, reveals that the distribution of these fluctuations in the neuronal network and the galaxy network is remarkably similar. This pattern is distinct from fractal systems like clouds or tree branches, suggesting that both the brain and cosmic web are scale-dependent, self-organized structures, not simple fractals.
