  The pervasive presence in space of a flux of high-speed, electrically
uncharged dark matter particles is examined here for potential consequences.
Dark matter interactions with ordinary matter are considered, and a model of
the dark matter flux is developed. In this model, the property of matter that
we designate as mass is a measure of the interaction cross section of ordinary
matter with the flux of dark matter. From this model emerge effects similar to
certain quantum phenomena, and also a flux-mediated attractive inverse-square
force between particles of ordinary matter. The occurrence of effects
resembling both quantum phenomena and effects resembling gravitational
phenomena in this model may enable a straightforward examination of convergence
of gravitational physics and quantum mechanics.
