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
