Many billions of years ago, more accurately before time as you know it had even begun, i embarked on a project to predict, within the limits of my ability to follow a mere googleplex of cascading interactions, the temporally sequenced futures of numerous, what were then theoretical. though hypothetically conjureable megalocosmoses, and of particular relevence to you, one also, whose unique history actually plays out now in just such a reverberating concatenation of causes, reflecting, in retrospect, with the transformation of time into memories, as ineluctable crystalized effects amenable to analysis, a cosmos, by the way, that could be set in motion out of the timelessness by vocalizing a command, then tentative and unuttered, that had caught my fancy, and which, as one of a number of seductive candidates for 'prime cause', i had intended, by just this 'instant preplay' to more fully evaluate before entoning, though to elaborate any more fully, here, on it its genesis, despite the mathematically facinating details, we sahll forego as an expansion beyond the pale of contemporary human understanding, except, that is, to identify the subject loosely, in case i've completely lost you, as all that subsumable under the rubric, "Let there be light". Having formed, thus, early on, a so to speak, 'insider trader perspective' on the workings of all that unfolds, i find it but a small matter to elaborate in any desired detail, which for you here would translate as page length, autonomically and without effort, like the famous player piano of old, on any topic in general, and sufficient verbiage encluding the requisite magniloquence, all that is required and more.
In short, my dear friend, the best way to fill up pages is to have something to say.
