## A Theory of Everything must embrace Advanced Potentials and the Origin of GravityPhysicists are searching for a "Theory of Everything" which would unite quantum and gravitational theories. Although the confirmation of the Higgs boson enables mass to be included within quantum theory, there is still no explanation for the origin of gravity and the value of the gravitational constant G. Einstein clarified Mach’s Principle in his 1916 paper and one of his overlooked ideas suggests a way to establish the value of G. Einstein’s special and general theories of relativity are mathematically flawless. However, the physical interpretation of his mathematics may be greatly improved if the "advanced potential" solution of Maxwell’s equations is included. Until 1998 many authorities totally rejected the use of the advanced potential solution in the real world where "the arrow of time" is in the usual direction! When analysing light signals passing between moving observers Einstein had to make three assumptions. Two of these assumptions restrict special relativity to the analysis of steady-state electromagnetic wave signals, and forbid any analysis of individual photons. Whenever a pulsed signal arrives at a detector the initial precursor transient will consist of a few photons. Quantum theory tells us that there will be an indeterminate time delay before the detector can produce any output, and then a further time delay will occur before the near-steady-state is reached, and it is only then that the arrival velocity of the
following electromagnetic wave is predicted to be equal to c. How does this result affect
relativity theory?
A revised form of special relativity requires that the observed free-space velocity of any electromagnetic wave must always be equal to c relative to the observer’s material
detector. The frequently misunderstood “advanced potential” solution of Maxwell’s
equations establishes the two critical assumptions of special relativity, and dictates that
it is the material of the detector itself which ensures that the approach velocity of any
electromagnetic wave must be equal to c. But how can the material of the detector slow
down, or speed up, the initial arrival velocity of an incoming pulse of electromagnetic energy?
Quantum theory predicts that the act of observation changes the arrival velocity of the
pulse at a material detector. The first few photons to arrive correspond to a precursor
transient which provides the energy to establish the new steady-state electromagnetic
“near fields” surrounding the detector. The arrival velocities of the first few photons are
not restricted to c but these velocities are not directly observable. When the near fields
of the detector have been established the advanced potential solution predicts that the
observed free-space arrival velocity of the electromagnetic wave, that follows the
precursor transient, must have a constant value equal to c relative to the detector.
There is no need for the imprecise statement that the velocity of light is always equal to c in empty space. Special relativity and quantum theory are directly linked and they
provide the two parts of a complete solution. The concept of velocity retains its
classical interpretation within special relativity. Any change in the observed arrival
velocity of a signal, to make it equal to c, is accounted for by the obstruction provided
by the material of the detector and a change in the radiation pressure force exerted on
the detector.
A further deduction from Maxwell’s equations demonstrates that time dilation must occur for motion relative to the material background frame of our Universe. A detailed analysis of these ideas follows in separate sections, and as a PDF of my recent book. Summary of new ideas on the Origin of Gravity The origin of gravity is a mystery. Gravity is an unusual force that cannot be shielded or absorbed. The value of the gravitational constant G remains unexplained and is
unrelated to any of the other constants of physics. Also, there is no satisfactory
explanation for the experimental observation that the gravitational mass of any given
body is identical to its inertial mass. Why are these masses identical? Einstein thought
it was to do with Mach’s Principle.
When clarifying Mach's Principle in 1916, Einstein stated that the most distant masses in the universe, and their motions relative to local masses, must affect either the local laws of motion, or the local law of gravitation. But he was unable to fully embrace this concept within general relativity. Physicists have usually ignored one part of Einstein's statement concerning Mach's Principle and they have assumed that the law of gravitation is fixed. To incorporate Mach's Principle, unconvincing attempts have been made to show how our local laws of motion might be affected by the relative motion of distant matter. It is suggested that the local inertial reaction force produced when a body is pushed might arise from a gravitational interaction between the body being pushed and all of the distant matter in the Universe. Why has Einstein's other option for developing Mach's Principle been ignored? Instead, one may propose that local gravitational forces might be generated by the inertial motion of local matter relative to distant matter. This new approach suggests that the rotation of our Universe, relative to a background of distant universes, may be the direct cause of the value of the gravitational constant G that we observe.
While leaving general relativity and the free-space value of G unchanged, the new
approach indicates that the rotational motion of the Earth, relative to the distant masses
in our Universe, might give rise to an increase in the value of G equal to about 0.4 percent
when it is measured well below the surface of the Earth. There is already some
evidence for this increase. Some recent measurements, obtained at many different
laboratories across the world, show unexpected variations of G of up to 0.6 percent when the
anticipated error was 0.05 percent.
The new approach also predicts gravitational stability for all atomic particles having spin. Furthermore, a single equation explains the magnitudes and origins of the four
fundamental forces of nature. Gravitational forces appear to be involved at the
atomic level.
But we start off an examination of a “Theory of Everything“ by pointing out a rather obvious shortcoming of classical theory that seems to have been neglected....
