I had thought images of Laniakea looked similar to the central nervous system [from other photos/pics] and thought I was alone in anthropomorphizing the image in that way.
Then I saw your side-by-side comparison with the brain cell - which is pretty remarkable in it's resemblance. It does make one wonder about the similarities & patterns within the universe all around us - or in this instance, WITHIN us.
thanx GPN though when looking for one of each which I thought would appear similar when placed together, I'd found someone already did that years ago so just posted that person's pic. Ya gotta be fast to be first on the internet.
