To find a solution to many unsolved mysteries in physics, a new theory has been proposed. This theory proposes an external source of energy that is responsible for all so-called fundamental forces associated with the elementary particles. New dimensions called O-reality and O- imaginary, which are sources of external energy to our 3-D universe, are introduced. These are energy-filled totally symmetric dimensions wherein time does not exist. Current theory states that the energy of elementary particles is by virtue of an external source and not an intrinsic property. This theory integrates quantum particles with gravitational force and holds the potential to solve most existing unsolved problems. A mathematical model is developed using this theory for the calculation of the gravitational force. The results of the gravitational force obtained by this model, wherein the energy source responsible for the gravitational force has an external origin, are in accordance with Newtonian values. This theory brings quantum physics and gravitational force under one umbrella and opens the door for the reasoning behind many unsolved problems in physics. This theory leads to a new approach towards explaining the origin of Universe, dark matter, dark energy, quantum entanglement, double slit experiment and wave particle duality, superposition, holographic universe, uncertainty principle, origin of time and its unidirectional property, increasing entropy.
