This is Cool

An international team of physicists working in the bottom of an old iron mine in Minnesota said Thursday that they might have registered the first faint hints of a ghostly sea of subatomic particles known as dark matter long thought to permeate the cosmos.

The discovery occurred at the Soudan mine, which we visited just a few years ago. The only dark matter we saw was when they shut out the lights on us.

Here's more on the enormity of the discovery:

Confirmation of the particles would also constitute the first evidence for a new feature of nature, called supersymmetry, that physicists have been seeking as avidly as the astronomers have been seeking dark matter. It is central to theoretical efforts like string theory, which unify all of the forces of nature into one mathematical expression.

Super cool.
