| Dec 17, 2015 at 18:10 | comment | added | SF. | @jameslarge: last sentence of the question. WHAT other observations? Specifically on small distance scales (solar system radius ~ touch distance), as we've mapped galaxy-sized and larger concentrations quite accurately. | |
| Dec 17, 2015 at 17:47 | comment | added | Solomon Slow | The word "dark" means that it is not detected. "Dark" is what astronomers/cosmologists call anything that they can not see, but whose existence they infer from other observations. | |
