The human brain looks suspiciously like the universe


When you compare the neurons in the human brain to the cosmic web of galaxies, they look suspiciously the same… And when scientists compare the two structures numerically, the similarities become even more astounding.

Why does the brain resemble the universe?

New research show that the human brain and the Universe look similar and behave similarly.

Both brain and universe are complex networks of neurons and galaxies, respectively.

There are nearly 100 billion neurons that form 100 trillion neural connections in the human brain interconnected into a hierarchical network of nodes, filaments, and neural clusters. Similarly, the observable universe contains about 100 billion galaxies, forming a cosmic web of string-like filaments composed of ordinary and dark matter. The resulting image looks strikingly similar to a network of neurons.

The scientists explain in their article: “Although the relevant physical interactions in the above two systems are completely different, their observation through microscopic and telescopic techniques have captured a tantalizing similar morphology, to the point that it has often been noted that the cosmic web and the web of neurons look alike.”

The scientists then analysed the two systems quantitatively, using a method called power spectrum analysis. Results show: “… 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.”

The scientists also compared the average number of connections per node and how these nodes clustered together. And the results are also surprising: “Once again, structural parameters have identified unexpected agreement levels. Probably, the connectivity within the two networks evolves following similar physical principles, despite the striking and obvious difference between the physical powers regulating galaxies and neurons.”

It is rather baffling and impressive that the cosmic web of our visible universe may have more in common with the network of neurons in your brain than its individual galaxies and stars.
