The Standard Model of Particle Physics is held up as one of the most successful theories in physics, but it is littered with dubious renormalised infinities, fundamental particles that have never been directly detected and even fails completely to explain the force of gravity. In this paper I revive the idea of the aether which was proposed as the medium through which Maxwell’s electromagnetic waves travelled. By comparing the formula for the speed of light in free space to that of sound in any medium I have reinterpreted μ0 as the density of free space and ε0 as the compressibility of free space. I propose that the actual structure of free space is a tetrahedral lattice of nodes similar to many crystals found in nature and that these nodes are connected with identical connecting rods under compression. The length of these connecting rods is a new fundamental constant but with this very simple model I can easily explain the nature of, and derive values for Planck’s constant, h, the Gravitational Constant, G, the charge of the electron, e, the mass of the electron, me, the mass of the Proton, mp, the mass of the Neutron, mn, the Magnetic Moment of the electron, μe of the Proton μp, and of the Neutron μn In explaining the origins of these fundamental constants, I have also explained the nature of matter and light and the three main forces, i.e. Electromagnetic, Strong Nuclear and Gravity. In the case of matter, it explains the nature of inertial and gravitational mass and in the case of light it explains why the photon has no gravitational mass. This model also explains many unexplained phenomena such as β- decay parity violation, single particle interference experiments, Stern-Gerlach experiments, Bell inequality experiments, Aharonov Bohm effect and many more. It also has a very simple explanation for Dark Energy, Dark Matter and the Matter-Antimatter asymmetry.
