Gravity and Centrifugal Force In Higher Resolution
Gravity and inertia are much alike (Einstein)
Even so gravity takes a huge mass to cause the same force as in a centrifuge and there are other problems like how inertia in the frame of motion can be cancelled by linear motion while radial acceleration inward cancels gravity, so they aren't the same since an acceleration is not linear motion. Another reason to believe gravity and inertia are not equivalent is because mass causes gravity while inertia causes linear motion, so the more inertia, the emptier the space and this is not the same as a plenum. And this wouldn't be just be an exact cancellation, the opposition is nonlinear because if mass is like a solid and inertia being lightweight is more like a fluid, solids are more complex and fluids are more simple. Thus it seems Einstein's way of physics here is incomplete.
Two components of the field would explain both Einstein's Equivalence Causeology and distinction between both types of force; A higher energy low speed component common to both gravity and inertia may unify them. This component would not be attractive and would operate by inert impact of it's constuituents on masses since gravity if as strong as the force in a centrifuge with the same mass of the spinning wheel would be much stronger and
A second lower energy high speed component would just be in fields with mass and gravity and not much in power via centrifugal force.
To explain Einstein's Equivalence of Mass and Inertia (like that in a centrifuge) the higher powered near electromagnetic component would be used with both, and the distinction of the two would be caused by the lower energy field, this is not how Einstein conceived General Relativity with just empty space and time, and with no use of the flow of the field like this that would cause both what's common and uncommon about gravitation and inertia.
How these components act may explain the motifs of spacelike and timelike virtual photons. (Einstein's idea of the intervals was that they were faster and slower than light.)

The high energy field when being accelerated by the lower power component would add force to mass by pressure causing the force of gravity. This low energy component is lightweight, so it may both move much faster than light and not shield by lightening up to travel light (see my Physics Synopses link for evidence for Faster Than Light and experiments). The higher speed low density component is absent mostly in a centrifuge, and since inertia is much like gravity, both inertia and gravity would share the second, higher density, lower speed, component, this would explain Einstein's belief about how gravity and inertia are alike.
nly if the "inertial low energy electromagnetic" field common to both gravity and inertia is just made of low energy particles that would replace the high energy Higgs now being sought with the high energy physics "atom smashing" machines would gravity be explained by way of the pressure of a moderately dense field. For more evidence in support of my belief in a moderate lower energy field Click Here. If it were of high density like the Higgs it would be made of so much density gravity would shield, even (or especially) if the huge mass of each particle were "renormalized". If the wall formed by the balance of two huge mass densities, the inward and outward flow, were balanced so no gravity goes out, none would go in so all fields made of a high energy Higgs would shield or have huge density. A lower energy field would be more flexible because it would have to be able to change rapidly from a particle to a wave if it were the foundation field all the mass and energy were made of. For the light's wavelength to change with changes in the high speed observer's speed in special relativity, I use the assumption of the field that is lower in energy than the light but not so much lower it can't shape and mold what Einstein called "spacetime" well. And a lighter field could travel faster than light to shape the field in Special Relativity because it's somewhat lighter than light, and as I say in my synopses page you lighten up to travel faster with most common mass around us in the world, only a faster than light signal from the high speed starship could change the wavelength of the light before it reaches the ship since by special relativity, no signal can reach between the high speed ship and the light to change it.
