The most detailed dark-matter map of our universe is weirdly smooth
- karmakaze 5y ago> We know dark matter exists because we can observe its effects on all the stuff that’s swirling around in the universe. I don't even think I should keep readinv this. All we know is that outer/galaxies rotate about faster than expected accounting for known masses. It's a discrepancy between two calculations that don't fit our model of gravitation. Nothing more or less until we actually find a source other than proved missing matter.
