will discuss the tantalizing prospect that Dark Matter is a
relic of physics at the Planck-scale, where quantum gravity
effects are expected to become important. I will review
how physics at such high energy scales can produce
low-energy relics and describe the properties of Dark
Matter if it is in fact such a relic. I’ll then look at whether
there is any hope for a laboratory detection of Planck-scale
Dark Matter through its spin-couplings, taking advantage of
the recent great strides — thanks to medical physics
applications — in producing large quantities of
coherently-polarized nucleons.
