Galaxy Simulation 1 (IMAGE) Durham University Caption Computer generated images showing a disk galaxy from a modified gravity simulation. Images show (right side of image, in red-blue color) the gas density within the disk of the galaxy with the stars shown as bright dots. The left side of the images show the force changes in the gas within the disk, where the dark central regions correspond to standard, General Relativity-like forces and the bright yellow regions correspond to enhanced (modified forces). Images show views of the simulated galaxy from above and the side. Credit Christian Arnold/Baojiu Li/Durham University.
