Universal structures? Galaxies and neural networks ‘strikingly similar’

We — an astrophysicist and a neuroscientist — joined forces to quantitatively compare the complexity of galaxy networks and neuronal networks…

In total, the number of galaxies within the observable universe should be on the order of 100 billion. The balance between the accelerating expansion of the fabric of spacetime and the pull of self-gravity gives this network its spider-web-like pattern.

Interestingly enough, the total number of neurons in the human brain falls in the same ballpark of the number of galaxies in the observable universe.

The eye immediately grasps some similarity between images of the cosmic web and the brain.

It is truly a remarkable fact that the cosmic web is more similar to the human brain than it is to the interior of a galaxy; or that the neuronal network is more similar to the cosmic web than it is to the interior of a neuronal body. Despite extraordinary differences in substrate, physical mechanisms, and size, the human neuronal network and the cosmic web of galaxies, when considered with the tools of information theory, are strikingly similar.
