    Abstract

    High-energy collisions of particles may have created tiny black holes in the early Universe, which might leave stable remnants instead of fully evaporating as a result of Hawking radiation. If the reheating temperature was sufficiently close to the fundamental gravity scale, which can be different from the usual Planck scale depending of the presence and properties of spatial extra dimensions, the formation rate could have been sufficiently high and hence such remnants could account for the entire cold dark matter of the Universe.
