The Dark Matter Map

Dark MatterSo that’s what’s out there … Jason Palmer reports from the annual American Astronomical Society meeting in Austin for BBC News:

Researchers have released the biggest images yet detailing dark matter, the mysterious substance that makes up three-quarters of the Universe’s mass.

Each image, a billion light-years across, shows vast dark matter clumps and voids scattered through the cosmos.

The team from the Canada-France Hawaii Telescope inferred the dark matter’s existence by the way it bends light.

The images were presented at the 219th meeting of the American Astronomical Society in Austin, US.

The four images were taken at four different seasons of the year, each capturing a swath of the sky about as large as a palm held at arm’s length.

They are a big step forward in understanding both dark matter itself, and the means by which dark matter influences the way normal matter clumps into the galaxies we see in the night skies.

Together, they represent the images of more than 10 million galaxies, whose light gives the only hints of the large-scale structure of dark matter…

      besides the fact that we can now track dark matter and learn more from it, but you know, taking those first few steps helped you to walk, then to run, but obviously nothing of value was gained from you doing that either.

        The ‘practical application’ is just around the next theoretical corner, if only we had more funding…

    Imagine, if you can, that the universe actually extends beyond your immediate neighborhood and the distance from your front door to the local strip club.
