| Scientists seek other scientists for cosmology problem Posted: 28 Nov 2013 09:41 AM PST How do you measure something that is invisible? It's a challenging task, but astronomers have made progress on one front: the study of dark matter and dark energy, two of the most mysterious substances in our cosmos. Dark matter is intermixed with normal matter, but it gives off no light, making it impossible to see.

Now for the third time, an innovative competition has begun again with the goal of finding better tools for probing dark matter and dark energy. |
