WebOne profound result of Einstein’s theory of general relativity: gravity bends the path of light, much as it affects the path of massive objects. Very massive astronomical bodies, such as galaxies and galaxy clusters, can magnify the light from more distant objects, letting astronomers observe objects that would ordinarily be too far to see. WebNov 29, 2024 · The dark matter displaced by a galaxy 'displaces back', causing the stars in the outer arms of the galaxy to orbit the galactic center at the rate in which they do.
