As professor Stephen W Hawking said, then Grand Unified Theory comes into being, it should be a theory that philosophers, scientists and ordinary people can all understand easily and join in the discussion about it. The force that unify all forces is the fictitious force, and therefore all forms of energy ultimately comes from potential energy – that is the grand unified theory.
Fictitious force, or commonly known as “inertial force” comes out of reference, comparison, and relativity.
Fictitious force is also known as inertial force. Inertial force is all about “self wanting to be self”, “self preservation” or “survival” as in first Newtonian Law: “objects at rest tend to stay at rest, objects in motion tend to stay in motion”. Also, when looking at the First Law of thermal dynamics, we will find the same thing: “in a confined system, energy cannot be generated or lost”. This is a typical case of “it is what it is”.
Also because fictitious force is not real, therefore a form of “imaginary force”. By reasoning, when unifying with artists, one can say all forces are ultimately the force of imagination.
Above diagram shows gravity and electromagnetic force are the two states of the same inertial force, when looking from the two different view points of the dual vector space of < in | out > , between space & mass, at a macro level.
Above diagram shows strong force and week force are the two states of the same inertial force, when looking from the two different view points of the dual vector space of < in | out > , between space & mass, at a micro level.
