In a recent investigation, scientists have discovered remarkable similarities between two completely different systems: the intricate network of neuronal cells in the human brain and the vast cosmic web of galaxies.
The researchers thoroughly examined both systems, carefully analyzing their structures, forms, memory capabilities, and other characteristics. Through their quantitative analysis, they revealed that even though these systems differ greatly in size, spanning 27 orders of magnitude, they can exhibit comparable levels of complexity and organization.
This groundbreaking study was led by Italian experts from diverse fields, including astrophysicist Franco Vazza from the University of Bologna and neurosurgeon Alberto Feletti from the University of Verona.
The scientists highlighted in their research that the striking resemblance uncovered by their investigation indicates that the self-organization of these intricate systems is likely controlled by similar principles of network dynamics, despite their vastly different scales and operational mechanisms.
A significant finding from the research was the comparison made between the brain’s neuronal network and a universe in itself, consisting of around 69 billion neurons—similar to the network of at least 100 billion galaxies in the observable universe.
Moreover, both networks—neurons and galaxies—display a distinct structure with nodes linked by filaments. Examination of the average number and clustering of connections within nodes showed noticeable “agreement levels” in connectivity, suggesting similar underlying physical principles, as pointed out by Feletti.
Moreover, fascinating similarities can be observed in the makeup of these formations. The brain is composed of about 77 percent water, while dark energy makes up roughly 70 percent of the Universe—both playing passive roles within their own systems. On the other hand, galaxies or neurons account for approximately 30 percent of the mass in each system.
In addition, interesting parallels can be seen in the structure of these entities. The brain is made up of around 77 percent water, while dark energy permeates about 70 percent of the Universe—both serving as passive elements within their respective systems. Conversely, galaxies or neurons make up roughly 30 percent of the mass in each system.
According to Michio Kaku, it is truly captivating to consider that the most complex creation of Mother Nature in the entire universe resides within our own minds. In order to discover a planet that could potentially support life and intelligence, one would have to travel a minimum of 24 trillion miles to reach the closest star. Astonishingly, our brain operates on a mere 20-30 watts of power, yet it outperforms even the most sophisticated supercomputers in terms of computational abilities.
