Detectors in the mine, part of the Cryogenic Dark Matter Search experiment, were

WIMPs.

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).
