| 100% | We want to find as direct evidence as we can that a massive compact object, a dark star, |
| 100% | is pulling on a companion star. |
| 100% | So the way to do that is to measure the motion of the companion star. |
| 100% | Since you can never directly take a photograph of a black hole, it just appears black, the |
| 97% | best you can really do is measure its influence on material around it. |
| 97% | We can then look for minute shifts in the color of the light coming from the star. |
| 97% | And if these shifts are found and they go back and forth periodically, then that's |
| 97% | an indication that something is tugging on the star. |
