[Link] The map stretches half way back to the beginning of the universe and shows that dark matter has formed into "clumps" as it collapsed under gravity. Other matter then grouped around these clumps to form the visible stars, galaxies and planets....Scientists said the new images were equivalent to seeing a city, its suburbs and country roads in daylight for the first time. Major arteries and intersections become evident and a variety of neighbourhoods are revealed. Now that we know where it is, the scientists say, the next step is to figure out what it is. jon posted this at 8:52 AM |
