That isn't quite true, depending on your meaning of "isolated".
General relativity is still the best explanation of gravitation known, and the source term is the stress-energy tensor, which (classically) adds up pretty much everything that's physically real---masses & fields.
So far, no prediction of general relativity has ever been invalidated---except perhaps the unusual Tajmar experiment, but nobody really knows what that means.
What exactly do you mean by this? Is this Verlinde's stuff?

We can causally associate the movement of a 'particle' (the electron) with the effects of a magnetic field.
Gravity just poofs out, rather mysteriously, from objects with mass. Since pretty much everything has mass, it makes it pretty hard to figure out what, exactly, give matter its self-attracting property.

Planck constants effectively put a limit on the amount of information that can exist in any given volume of space. Conservation of energy means that the energy necessary to process interactions between molecules must come from somewhere.
Granted, in the immediate, the theories are completely interchangeable - space-time and the gravitational constant are mathematical conveniences as opposed to real solutions, which poses a problem when attempting to predict the behavior of systems not observed in nature.
If you were to create a "wormhole" as Einstein describes, you would not be able to travel back in time. Such a notion is silly. Even Einstein recognized this. Because he married space and time so closely together in his theory, he missed the obvious. Travel through a wormhole may only take a fraction of a second - doesn't matter if it is instant or not - it's not the interim space we need to be concerned with, it is the difference between the point of origin and the point of deposit.
Let's say we are going to jump through a wormhole with ends placed conveniently in the galactic void, and one in proximity to the galactic center. The point in the galactic void is influenced very little by gravity - therefor time is artificially accelerated by comparison to the point being influenced by more gravity near the galactic center. Were you to jump from the edge of the galaxy to the center, you would exit with a burst of Cerenkov radiation - as your ship will be 'hot' compared to the much colder space. The greater the difference in relative gravitational densities, the more intense your entry will be.
EMF behaves rather similarly, though in a much more simple fashion. A signal sent from the galactic edge to the galactic center will be blue-shifted upon its exit from the worm-hole. Predictably, a signal sent from the center to the edge of a galaxy via wormhole will be red-shifted. At some point, it would be possible to violate Planck constants - transmitting gamma radiation to a region of high gravitational density will cause all kinds of chaos.

See above. It's not that general relativity is wrong - it's that it was off the mark, and people have been too caught up with proving or disproving theories to simply go back and re-hash the idea. Of course - what I just did up there was a very watered down and simplistic unified theory.

If gravity is not a field - like a magnetic dipole, or a force with a measurable carrier, then you can't really create an anti-gravity field, or a 'gravity shield.' You can, however, theoretically make some device capable of directly manipulating inertia and/or the entropic energy state (accelerating to escape velocity is far easier when your vehicle is already at that energy potential on the subatomic level). Which would fit one of your criteria for being "close enough" to antigravity. It would actually be far more useful and far superior to an anti-gravity field... but that's another story.
The other type of device I was describing was purely based off of a related area of interest. I've long been interested in what happens when you take multiple sources of EMF and orientate them so as to be able to create specific geometric 3d waveforms by manipulating the emissions of each source. Hutchison fans will jump up and down and wet themselves - I'm not so sure he really did much... or knew what he was doing - nor do I really care to try and replicate his claimed results.
Anyway - I've been interested in what happens when you do one (or more) of several things. For starters - let's say you use these multiple sources of EMF to create a region of space that is forced to handle a field that is attempting to oscillate faster than the speed of light will allow. What happens? By manipulating this region of positive and negative interference, would it be possible to create magnetic fields that appear to originate from 'free space'?
If such could be done (or any other method of generating a free-standing magnetic field were to be found), it would not be hard to then use a secondary device to push or pull off of those free-standing waves - potentially invalidating the need for a reaction mass.
The 'drive' would be an "impulse" drive - constrained to relativistic velocities unless its operation results in some unforseen capability (though I have no reason to suspect it would).
Of course - this would only be displacing the role of a reaction mass with the energy input necessary to create a free-standing magnetic field (and it may even prove more realistic and/or efficient to instigate energy-particle conversions and use that as a reaction mass - a sort of pseudo-reactionless drive that creates reaction mass from energy as required). I've no way of estimating the relative energy costs.
It could all be bunk, and I would build the ultra-precise masers from hell to later use to remotely cook my food and terrorize florescent light bulbs. But either way, I end up with something fun and cool. When I get bored - I can just toss stuff into the middle of the field and see what happens - maybe I'll discover something useful, or equally diabolical.
I don't understand how this is any different from the fact that an electric monopole and a magnetic dipole "poofs out" rather mysteriously from elementary particles with charge, like an electron.
You've lost me here.
Gravity doesn't slow time anymore than a refrigerator does - the mechanics are simply at a different level.
From the standpoint of information equivalence, it makes sense for matter to inherently 'slow' the mean rate of activity down when in proximity.
???? As I understand it, energy is necessary to create configurations which in a subspace have lower entropy (i.e. the 2nd law of thermodynamics). Other than that I don't understand what you're trying to say.
