    Abstract

    In this lecture we review a fundamental connection between the number of particle species and the nature of gravitational interaction at the shortest length-scales. The key role in establishing this connection is played by the well-understood properties of macroscopic black holes, combined with effective field-theoretic approach to gravity. One universal outcome is, that the existence of particle species in low energy theory inevitably replaces the Planck length by a longer fundamental scale. Application of this phenomenon for the solution to the Hierarchy Problem fixes the number of species at 10 32.
