Scientists say the human brain resembles the cosmos Both neural and galactic networks have the same structure, pointing to a fractal universe. by Tibi Puiu November 19, 2020 in News, Science, Space

Side by side pictures of brain cells and a cosmic web of galaxies make it difficult to tell the two apart. So it can seem that the universe is like one giant brain or vice-versa, there’s a tiny universe in each of our brains. That’s not merely some entertaining thought. In a new study, an astrophysicist and a neurosurgeon have documented the striking similarities between cosmic networks of galaxies and neural networks of brain cells.

Alberto Feletti, a neurosurgeon at the University of Verona, and Franco Vazza, astrophysicist at the University of Bologna, performed a quantitative analysis of neural and cosmic networks, showing that the natural physical processes lead to similar structures even when differences in scale can be greater than 27 orders of magnitude.

The human brain contains approximately 69 billion neurons, whereas the observable universe consists of a web of at least 100 billion galaxies. In both galactic and neural networks, just 30% of their masses are composed of ‘working’ masses, such as galaxies and neurons. The rest of the 70% of matter plays an apparently passive role: water in the brain and dark energy in the observable cosmos... more
