  I give a summary review of the research program using noncommutative geometry
as a framework to determine the structure of space-time. Classification of
finite noncommutative spaces under few assumptions reveals why nature chose the
Standard Model and the reasons behind the particular form of gauge fields,
Higgs fields and fermions as well as the origin of symmetry breaking. It also
points that at high energies the Standard Model is a truncation of Pati-Salam
unified model of leptons and quarks. The same conclusions are arrived at
uniquely without making any assumptions except for an axiom which is a higher
form of Heisenberg commutation relations quantizing the volume of space-time.
We establish the existence of two kinds of quanta of geometry in the form of
unit spheres of Planck length. We provide answers to many of the questions
which are not answered by other approaches, however, more research is needed to
answer the remaining challenging questions.
