This post is a direct lead-up from the last. I kept thinking about "energy direction = dimension" and a lot of things seemed to fit.
I began by thinking of the smallest particles we know being a result of combined flows of energy. This didn't sit quite right with me, but then I thought: what if the base of everything we see around us, no matter its level of construction, is in fact energy flowing in the same direction, and that very energy is the base of attraction we call gravity? If every molecule contains atoms that contain hadrons that contain quarks, it doesn't really matter the stage of construction, does it? If it is proven that every particle we know contains some gravitational force, this adds up to something for me.
We know that when particle combine in massive quantities, a huge gravitational pull is created; the higher end of this phenomenon we call black holes. Now, scientists have stated since decades that gravity at the centre of some black holes is so enormous that matter practically ceases to exist - but what if it does cease to exist - at least in our direction, or dimension? What if the forces accumulate in numbers so great that it causes them to... change direction? They would essentially disappear - at least to our dimension.
Take this model to the other end of the scale: we have quite recently begun experimentation with particle accelerators. Isn't the aim of this endeavour in the same high-energy direction as the centre of a black hole - combining particles under the duress of super-high energy levels? I have to check my facts, but it would seem to me that in some atom collisions, some quarks had "disappeared".
Finally, back to the big bang. What if the origins of the world as we know it wasn't an explosion (in the conventional sense of the term), but an accumulation of energy in one dimension so massive that it suddenly... changed direction? This model of 'injection' of energy from a single point redirected into our present direction would explain many things - namely the limits of our universe (the 'nothingness' beyond), and it would also define what dimensions are as well as the infinite possibilities of what directions they may take - or at the least, it can show the uniqueness of the dimension direction we are travelling in, and the difficulties and conditions of travelling to others.
Addendum: At a first glance, the above seems to be consistant with Einstein's E=mc² - but if his equasion was used as an equasion mapping containment, or comparison (mass/energy), and not conversion? I also have doubts about the constance of 'c' (the speed of light)... in my attempt to make a timeless model, a certain element of c (if it were to contain or be a result of a 'flow' tying us into our present direction) would enter into - or be substracted from - both sides of the equasion. More later.
