This mindblowing simulation of the universe covers a billion square light years of galactic material, magnetic fields, and dark matter. It appears that the universe looks just like the neural network inside the human brain...as if the universe is withing some macrocosmic entity.
This a video from the IllustrisTNG project http://www.tng-project.org/
It shows time evolution of the cosmic magnetic field strength. Blue/purple shows regions of low magnetic energy along filaments of the cosmic web, whereas orange and white indicate regions with significant magnetic energy inside halos and galaxies. The displayed region is taken from the TNG100 simulation and is 10 megaparsec wide. The Illustris TNG project is an ongoing series of large, cosmological magnetohydrodynamical simulations of galaxy formation. The project as a whole is led by Volker Springel at HITS, in collaboration with researchers at MPIA, MPA, Harvard, MIT, and CCA. http://www.tng-project.org/people/
