Dark matter may have been "felt" for the first time deep in a Minnesota mine,
physicists say.

Detectors in the mine, part of the Cryogenic Dark Matter Search experiment, were
tripped recently by what might be weakly interacting massive particles, or
WIMPs.

I didn't know the Hamster lived in a Minnesota mine.

"If WIMP detections are confirmed by other experiments, then
scientists
will likely want to know where the particles are coming from.."

I thought the Dark Matter these days originated in Cliff and TMT's postins.

If the unknown state cannot be found
out—as is indeed the case for isolated
quantum systems—then one can make a
persuasive case that such states are subjective,
and that quantum state vectors are
merely records of the observer’s knowledge
about the state of a fragment of the Universe
(Fuchs and Peres 2000).
