Abstract: The two pillar of modern theoretical physics research are Quantum Mechanics
(QM), which describes the internal structure of atoms, and General Relativity (GR), a theory of
gravity in terms of curved space-time on the large scale. While both theories are very
successful when confined to their respective length scale domains, many problems arise when
trying to combine them together to form a viable quantum theory of gravity, which still has not
been achieved after over 70 years of intensive effort.
A large part of this challenge rests upon the fact that the two theories use radically different
mathematical languages to effectively describe them. With this in mind, many researchers
worldwide seek to find a common mathematical framework in which to both describe QM and
GR in order to understand how they can be effectively combined together. However, this
approach by itself may be completely inadequate, given the lack of any physical data to justify
