Claim summary · not a verbatim quotation
Visual images of human neural tissue look identical to images of the observable universe.
The finding
What the evidence shows
A 2020 study by an astrophysicist and a neurosurgeon did find real similarities between brain tissue and the large-scale web of galaxies: both form clustered networks of nodes and filaments, and some structure statistics match over a limited range of scales. The same study found clear differences, including richer fine detail in the brain samples and no match on large scales, and the authors call the overlap suggestive. So the two look similar in some respects, not "exactly the same." Image comparisons showing the two structures matching across all scales would prove this verdict wrong.
