the spiral structure of the second image is probably familiar to most regular readers of this blog as belonging to a distant galaxy... in this case, the beautiful whirlpool galaxy (M51).
the first colorful image demonstrates the spiral structure of the very powerful hurricane hugo that swept thru the atlantic ocean in 1989.
they look amazingly similar, eh? a major difference being that hurricane hugo was a few hundred miles across, whereas the whirlpool galaxy is about 50,000 light years (300,000,000,000,000,000 miles) across and about 30 million light years away! the difference in physical scale is immense, but the logarithmic spiral patterns observed in their structure are nearly identical.
here's another example...
the first image shows large scale structures in the universe from a computer simulation. you can see the web-like structure of many many galaxies in the yellow-ish clusters, with filaments of galaxies, gas and dark matter connecting the large clusters.
the second image shows how particular types of neurons in the brain of a mouse connect to one another.
the overall structures look amazingly similar between these vastly different natural phenomena!! i find this especially amazing considering the size difference between these two phenomena is 22 orders of magnitude!!!
if only we could reconcile or find any similarity between the two theories governing the most extreme scales in the universe.... the quantum mechanical understanding of the incredibly small... and the general relativity understanding of the unfathomably large.
