Possibility of Primordial black holes Collision with Earth and the
  Consequences
  In the context of the existence of primordial black holes (PBHs), they may
compose a fraction of the dark matter of the Universe. Assuming that PBHs fill
the dark content of the Milky Way Galaxy in the Galactic halo and dark disk, we
calculate the probability of collision of the PBHs with Earth. This collision
has different consequences as heating the interior of the earth through
dynamical friction and accretion processes. In this work, we calculate the rate
of collisions and a fraction of black holes that can be trapped inside the
earth. Finally, we compare the danger of PBH collision with the asteroid
impacts on Earth.
