MiHsC (the first model that explains inertia) works using horizons, which are boundaries in space between areas that can get information to us at light speed, and areas which can't, like black hole event horizons. If you accelerate away from a region of space fast enough it means that information there suddenly cannot get to you and an information horizon forms cutting it off. In MiHsC this horizon damps the zero point field on the side opposite to your acceleration vector, so you roll down a gradient in the zpf towards the horizon, and this models inertial mass. I wrote a twitter-poem to summarise this:
If you move to the right,
the left's out of your sight.
so a 'horizon' appears,
damps zero point fields,
pulling u back.
Inertia is that!
The idea of information horizons may seem abstract, but this model explains a lot (eg: galaxy rotation without dark matter) and there is one big clue that is obviously MiHsC-like. The biggest object we can ever hope to see is the Hubble horizon. Distant stars are moving away from us at faster than the speed of light, so their information is lost to us. This causes the Hubble horizon surrounding the sphere of the visible universe.
The other interesting observation, made by Reiss and Perlmutter in 1999, is that the entire universe is accelerating away from itself. This phrase is easy to say, but the universe is a pretty big thing. You may have tried to push a car which is maybe 1000 kg in weight, and if you're like me, you'll have had difficulty. The cosmos is 10^49 times heavier than that, and yet something is accelerating it! Modern physics just glibly invents this so called 'dark energy' but suggests no origin for it. The amount of energy involved here would be very useful if we could understand and therefore control it.
MiHsC provides the right amount of energy straight away. It can be explained using Unruh waves as I have before, and also in a simplified mechanistic way by the diagram above. The Hubble horizon is shown by the black circle. The red is the zero point field (energy usually unavailable to us, because it is spatially uniform). MiHsC means that the ZPF is damped between the yellow stars and the Hubble edge (see the orange areas) so that more energetic virtual particles hit the stars from the cosmic centre, then from the other direction accelerating the stars outwards towards the Hubble horizon. Note that the acceleration of the stars is due to their apparent vicinity to the Hubble horizon from our point of view. from their point of view it would be us near the horizon, and us accelerating. MiHsC predicts the cosmic acceleration very well.
Can gravity also be modeled this way? Could it be due to objects making sheltered regions in the zero point field (see the narrow orange corridors)? I have not yet managed to show the mathematically.
