| Oct 11, 2017 at 8:32 | comment | added | John Rennie | There is currently no evidence for gravitational lensing by dark stars or dark galaxies. Whether that is evidence against theor existence is debatable. | |
| Oct 11, 2017 at 8:19 | comment | added | safesphere | @JohnRennie Wouldn't the gravitational lensing be a potential evidence? The reference you linked also suggests other observations. | |
| Oct 11, 2017 at 8:16 | comment | added | John Rennie | What you are describing is often called a dark sector or self interacting dark matter. However there is currently no evidence beyond the wilder imaginations of theoreticians that such dark sectors exist. | |
