  We discuss possible ways to observationally detect the superdense cosmic
objects composed of hypothetical sub-constituent fermions beneath the
quark/lepton level, recently proposed by us. The characteristic mass and size
of such objects depend on the compositeness scale, and their huge density
cannot arise within a context of quarks and leptons alone. Their eventual
observation would therefore be a direct vindication of physics beyond the
standard model of particle physics, possibly far beyond the reach of the Large
Hadron Collider (LHC), in a relatively simple and inexpensive manner. If relic
objects of this type exist, they can possibly be detected by present and future
x-ray observatories, high-frequency gravitational wave detectors, and
seismological detectors. To have a realistic detection rate, i.e., to be
observable, they must necessarily constitute a significant fraction of cold
dark matter.
