There have been proposals that primordial black hole relics are
the sources for dark matter. In the absence of a solid theoretical
foundation, such notions remain vague. We argue that the
generalized uncertainty principle (GUP) may prevent black holes
from total evaporation in a similar way that the standard
uncertainty principle prevents the hydrogen atom from collapse.
Specifically we invoke the GUP to obtain a modified Hawking
temperature, which indicates that there should exist non-radiating
remnants (BHR) of about Planck mass and Planck size. Combining
this argument with the hybrid inflation model, we show that
primordial BHRs can be the primary source of dark matter. We
discuss the post-inflation cosmology and possible signatures
associated with this notion.
