In this Theory, “Mass is Equivalent to Length of Imaginary Straight Line Segment” and “Direction to Imaginary Line Segment is Intrinsic Property of that Particle which is Equivalent to its Intrinsic Spin”. With this concept, all fundamental particles, Fermions and Bosons are described as Quanta Imaginary String particles with definite direction. For e.g. Unidirectional Imaginary Straight Line with fixed length are Massive Spin ½ Fermions; while Unidirectional Imaginary Quanta Curved Lines are Massless Spin 1 Bosons. Thus, it gives co-relation between Massless (Curved Imaginary Line) and spin = 1 properties of Boson as proved in QED theory. All Fundamental particles of Standard Model and Beyond Standard Model are arranged in one Simple Diagram in 3 Folds (Bottom Fold, Middle Upper and Lower Folds and Top Fold) and are projected in 4th Imaginary Dimension in order of decreased in Mass from TeV to approx. 0 eV. This Theory is Beyond Standard Model because it predicts New Fundamental Particles viz. Dark Matter (Spin=0 Massive Boson) along with Gravitons (Spin=2, Massless Bosons); 4th Pair of Neutrinos, Vertical Massless Boson (VMB) Particles and Tri-Axis Massive Boson (Spin=0) particle. Discovery of these new particles will act as Solid Proof to this theory. With this 3F4D representation of the Universe at atomic and sub-atomic level, it solves lot of current problems of SM of Particle physics like Matter-Antimatter Asymmetry, Origin of mass of hadrons like protons, Origin of mass and L.H. nature for neutrinos, Wave-particle duality of particles etc. giving true insight of fundamental particles. With proving that, Dark matter is not a Quanta Particle, rather it is a Single Entity and spreads/ expands throughout the Universe in the form of “Web of Spider”, it shows space-time is not empty, but it is filled with Continuous lines of Dark Matter and we, materialistic Massive objects are floating/ sailing w.r.t. current of this vast ocean. Correlation of its Continuity with Time, gives new definition to Time: “Time is neither Illusion nor 4th Dimension, but, it represents Continuous Flow of Single Entity, Dark Matter”. Space-Time is not Empty and is filled with Massive Dark Matter, hence, we have to add more terms to Newtonian Gravitational Equation to account for Gravitational Strength of Mass of Surrounding Dark Matter which represents Curvature of Space-Time in terms of Increase in its mass-density w.r.t. to Mass-Density of Flat Universe. Finally, using an Empirical Formula (h=k*c*Q; k=Boltzmann’s Constant=Mass in TeV Range) and Inverse relation of Mass-Density of DM with Age of the Universe (H^2=Constant*G*Mass-Density of DM); Unification of Gravity at TeV is achieved without consideration of “Gravitational Constant, G”, hence, Planck’s Scale is not required.
