In the dark
Dark matter is the commonest, most elusive stuff there is. Can we grasp this great unsolved problem in physics?
Alexander B Fry
No. Dark matter is the simplest solution to a complex problem, not a complicated solution to simple problem. It is not clear what the ‘need’ for dark matter indicates about our state of knowledge of the universe. The standard model of cosmology is supported by vast amounts data including but not limited to: the cosmic microwave background, the statistical distribution of galaxies in the sky, colliding clusters of galaxies, gravitational lensing, baryonic acoustic oscillations, and galaxy velocity rotation curves. These robust observations combine expertise and independent analysis from many fields of astronomy. All data are in strong agreement with a cosmological model that includes dark ...
