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.."

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

[ If the unknown state cannot be found out=97as is indeed the case for isolated quantum systems=97then one can make a persuasive case that such states are subjective, and that quantum state vectors are merely records of the observer=92s knowledge about the state of a fragment of the Universe (Fuchs and Peres 2000). ]
