Cosmologists have produced an enormous map of the distribution of dark matter in our Universe, tracing the invisible substance by monitoring its gravitational effects on light.

…

Dark matter is about five times more abundant than the matter we can see. Although invisible, its presence can be detected because it curves space-time.

Sounds exciting but I am still not sure why.

1. Physicists mapped unstuff they call Dark matter using a 570 megapixel digital camera (~10X the camera on the rumored Chinese smart phone called Oppo)

2. Shouldn’t they at least try to explain why this *matters*? No one I know seems to care
