A previous preon model for
the substructure of the standard model quarks and leptons is completed to
provide a model of Planck scale gravity and black holes. Gravity theory with
torsion is introduced in the model. Torsion has been shown to produce an
axial-vector field coupled to spinors, in the present case preons, causing an
attractive preon-preon interaction. This is assumed to be the leading term of
UV gravity. The boson has an estimated mass near the Planck scale. At high
enough density it can materialize and become the center of a black hole. Chiral
phase preons are proposed to form the horizon with thickness of order of Planck
length. Using quantum information theoretic concepts this is seen to lead to an
area law of black hole entropy.
