This is the
technology of being able to manipulate neutrinos as other particles and
waves are manipulated. The trouble is that neutrinos normally
don't interact with matter much at all. In the real world, our
best neutrino detectors have trouble detecting a dozen neutrinos from a
single supernova (astronomical numbers of the particles go THROUGH the
detector, however).
Sensors which can reliably sense neutrinos would be
useful for their ability to look through great thicknesses of matter
and see the slight changes in neutrino density from distributions of
that matter. Stasis fields, neutrino modification devices, and
anything else that blocks or moves large fractions of neutrinos would
show up extremely blatantly on a neutrino detection screen.
These neutrino detectors make possible the practice
of searching for objects stored in
stasis
fields from ancient civilizations. (See Larry Niven's Known
Space series and Vernor Vinge's Realtime books). Once this
technology is available, one may find stasis objects in/on planets,
asteroid belts, and even stars (stasis fields are essentially
invunerable after all) all over one's civilization. They may be
found without the detector, however. Care should be taken when
approaching such an object, however, as one would make an ideal lure
for traping an unfamiliar race and capturing one of their ships for
examination.
