Introduction:
A Theory of Everything (ToE) or final theory, ultimate theory, or master theory, is a hypothetical, coherent, single theoretical framework of physics, which explains and links all physical aspects of the universe. Finding a theory of everything is one of the major unsolved problems in physics. In the last centuriy, two theoretical frameworks have been developed that, as a whole, most closely resemble a theory of everything. The two theories upon which all modern physics rests are General Relativity (GR) and Quantum Field Theory (QFT).
General Relativity:
GR is a theoretical framework that focuses on the force of gravity, to understand the universe in both large-scale and large-mass regions: stars, galaxies, galaxy clusters, etc.
Quantum Field Theory:
TCC is a theoretical framework that focuses on three non-gravitational forces to understand the universe in both small-scale and low-mass regions: subatomic particles, atoms, molecules, etc.
TCC successfully implemented the standard, unified model of the interactions (called Grand Unified Theory) between the three non-gravitational forces: weak nuclear force, strong nuclear force and electromagnetic force.
Reality:
We can assume that these two theoretical frameworks describe our reality. Something is missing that unifies these two different scientific theories that describe our reality. But, what is reality?
