Is these statements true?

1. Released energy is a closing difference between two states. E.g: Balancing two electric charges, a falling object from point X to point Y.

2. All type of potential energy, as a function of the difference between the two states, is in comparison the same as kinetic energy.

3. Matter is by itself pure energy, and it must therefor exist a counter matter (Black matter) to balance this energy into nothing, as the sum of all energy in the universe must be zero.

4. Matter cannot exist without black matter

In other words: Energy is always the potential between two counter states.

Just to clarify - work = force times the distance through which it acts; specifically, the transference of energy equal to the product of the component of a force that acts in the direction of the motion of the point of application of the force and the distance through which the point of application moves.

(according to the dictionary)

What this basically says it that movement is always involved in work.  Applying force does not constitute work unless something is moved through a distance by a force.

Nothing is not energy - there is no matter - only energy form. All energy is in motion.

Magnets have movable energy yes, just about everything does to some extent, but I think the answer to the question you are asking is they are static. You can't really alter a permanent magnet's  strength or direction by doing something to the magnet itself (well, actually you can but generally end up with a messed up magnet so there's not much point in doing that)  , you have to alter the field itself  with something else external to it.

 As an example : You can use a magnet as part of  an electric circuit such as battery - wire- lightbulb- wire - magnet - battery and it will have very little effect on the magnetic field of the magnet except for the small field  created by the flow of the current itself. This will either add or subtract from the magnet's own field depending on direction of current flow and magnet orientation.

   Only if you tried to put too much through it and heated it too hot due to resistance would it really have any other effect and then just cause it to quit being a magnet.

Surely a magnet can do work on its own.  If you place a magnet on your fridge it will stay there forever doing work to resist falling/being pulled down by gravity?

A hook can then do work, by being hooked up into something and do work because it doesn't fall down? I don't think so. Please explain what you mean

I'm glad to see this discussion taking place. Most of us are not experts in the matter, which, contrary to a first thought, may be an actual advantage as we are not burdened by years of programming preventing us to get to the truth.

I have been wondering on how the concept of energy as being force x distance is a practical but not at all encompassing conceptual interpretation.

We have forces being provided by magnetic and or gravitational fields. The traditional physics say that one stores energy by moving an objet against the force field direction (we apply a force equal than the exerted by the field and we move the object a distance, so we get a Potential Energy stored in the object).

I have been wondering if energy could be described as a derivative of a force field against distance AND time. It is supposed that force fields are time invariant.

I have been following Steorn claims. There they have found that magnetic fields are indeed time variant, so they found a loophole where an potential energy can be gained out of a time variation of the field itself, thus, allowing for the creation (and also destruction) of energy! Holly CoE, we have a leak in the theory!

The best analogy I can find is like if we could find a time variation in gravity, we could lift a mass in the moment of weaker gravity and let it fall in a moment of strong gravity, thus creating energy out of the field itself!, we could als destroy energy by doing the opossite.

I think Milkovic's pendulums somehow exploit a loophole in gravity fields time invariance.

Can we get time inside the F x D expression? Can we? Can We?

I suspect the answer is lurking very near.
