Einstein's theory of relativity, E=mc², sums up quite nicely the interoperativity of all elements known to us, but I am persuaded that, in light of the missing 'god particle', they will one day be regrouped into one side of an equation describing the creation and behaviour of mass.
I can sum up all my past blogs on the subject into this: it takes a certain amount of energy, an energy beyond the speed of light, to transform "perfect matter" into a form with mass, or a form visible to us. Any energy short of the speed of light remains just that, energy. This would explain why light has a maximum speed, the existence (and 'weight') of dark matter, and why light can travel through a vacuum: in reality, light (energy), if it is not strong enough to affect the perfect matter, will simply 'surf' through it (like light waves through water, to bring the model down to a lower scale). Light (energy) in our present theories is affected by gravity, but I am persuaded that it is actually 'perfect matter' that is affected by gravity: it is the difference in its density that deviates an energy path, again much like light bends when travelling between air and water.
Energy, or 'charge', has a 'path' - it will travel freely unless blocked by (absorbed by) an object with mass. We know already that it is possible to create elements with a negative charge (or charged with energy on an opposite path), and should opposingly-charged elements meet each other, both will disappear completely. What's left over? I am persuaded that opposingly-charged elements, when meeting, 'trade' their energies and become, once again, perfect matter. I think for this to happen the energies of both elements must be equal in opposing directions.
It would make perfect sense that the beginning of our universe was a huge explosion of energy above the speed of light in all directions (charges); once the mass was created, and the energy of the explosion dropped below mass-creating levels, any energy left over from the explosion would be absorbed by mass-containing elements. The rest is consequential: positively-charged elements would be attracted to negatively-charged elements; if their charges were equally opposed, they would annihilate each other, and if their charges weren't equal, they would bind (in a 'stable' inter-annihilation struggle). It wouldn't surprise me if electrons were simply negatively-charged quarks 'left over' from this initial binding.
The question of charge also brings, once again, dimensions into question.
