Scientists have found evidence that suggests the universe is most likely nothing more than a gigantic human brain.

The network of neuronal cells in the human brain and the cosmic web of galaxies are two systems that operate in very different ways in terms of scale, yet scientists have discovered commonalities in their workings.

Researchers looked at the two systems’ structure, morphology, memory capacity, and other characteristics from a number of approaches. Their quantitative research showed that, despite size differences of 27 orders of magnitude, completely different physical processes may produce structures with equal degrees of complexity and organization.

Italian experts in two very distinct professions, neurosurgeon Alberto Feletti from the University of Verona and astrophysicist Franco Vazza from the University of Bologna, conducted the remarkable investigation on their own.

“The tantalizing degree of similarity that our analysis exposes seems to suggest that the self-organization of both complex systems is likely being shaped by similar principles of network dynamics, despite the radically different scales and processes at play,” wrote the scientists in their new paper.

The study’s most intriguing finding involves considering the neural network of the brain as a cosmos unto itself. There are around 69 billion neurons in this network. If you’re keeping track, there are at least 100 billion galaxies in the visible universe.

The specified nature of both networks—neurons and galaxies—with nodes linked by filaments is another resemblance. According to Feletti, the researchers came to the conclusion that there were distinct “agreement levels” in connectivity by examining the average number of connections in each node and the clustering of connections in nodes. This finding suggests that the two networks developed in accordance with similar physical principles.

When it comes to the differences in each structure’s makeup, there are also some fascinating parallels. The brain contains roughly 77 percent water, but dark energy makes up about 70 percent of the universe. Both of these substances are passive and play indirect parts in the structures in which they are used.

The opposite is also true; galaxies or neurons make up around 30% of each system’s mass.

Intriguing similarities between the changes in matter density in brains and the cosmic web were also discovered by the researchers.

“We calculated the spectral density of both systems. This is a technique often employed in cosmology for studying the spatial distribution of galaxies,” Vazza said in a press release. “Our analysis showed that the distribution of the fluctuation within the cerebellum neuronal network on a scale from 1 micrometer to 0.1 millimeters follows the same progression of the distribution of matter in the cosmic web but, of course, on a larger scale that goes from 5 million to 500 million light-years.”

“Believe it or not, sitting on our shoulders is the most complex object that Mother Nature has created in the known universe. You have to go at least 24 trillion miles to the nearest star to find a planet that may have life and may have intelligence. And yet our brain only consumes about 20-30 watts of power and yet it performs calculations better than any large supercomputer.” – Michio Kaku
