  It is shown how one, guided by causality, starting from so-called dynamical
triangulations, is led to a candidate of quantum gravity that describes our
Universe. This theory is based on W- and Jordan algebras. It explains how our
Universe was created, how cosmic inflation began and ended, how the topology
and the geometry of our Universe was formed, and what was the origin of Big
Bang energy. The theory also leads to a modified Friedmann equation which
explains the present accelerating expansion of our Universe without appealing
to the cosmological constant.
