The parabolic kalpa relies on the idea of flux. It relies also on the assumption that the divine is real and relevant, and that we descend from it. As time goes on we are separated more and more from divinity, ultimately reaching a bottom below which we cannot drop. After that extrema, we start to re-discover our connection with our makers, and ascend back up the sides of the curve. As implied by the image of the parabola, the descent is at first very fast and then flattens out and becomes nearly negligible, before steepening again on the ascent.
The connection with the divine can manifest in many ways. Most obviously, it is our separation by birth. The first, sharpest, drop was the first man, mer, or beast born on this world. Connection can also be knowledge - the first peoples had much more understanding of the nature of the world than we do now. Information is lost, forgotten, and misinterpreted, which manifests as the downward curve. Our general faith is of course another variable: how strongly do people believe in our gods and in our fathers? Splinters in philosophy and in religion cause further drops as people venture further from the truth. The upward ascent is governed by similar variables.
We know that our time began with the creation of the mortal plane by the gods, and the subsequent evolution of mortal life. It has also been http://www.gamesas.com/index.php?/topic/921446-world-eating-101 that the beginning (creation) of our time (kalpa) is indeed just the end of another time. The Dawn, of course, is so connected to the divine that we are hardly able to discern its events. We know that God and Man walked side by side, and that Towers, whose purpose is now all but forgotten, were the cornerstone of all Elven society. Alessia, Morihaus, and Pelinal's numerous incarnations are not out of place in the early first, and neither are the God-Kings of Morrowind or the Brass God of the Dwemer. Even the conception of Reman Cyrodiil late in the first era is fantastical in comparison with the mundane births of our modern emperors.
All this leaves us with the question of where on the parabola we are currently located. We are doubtlessly towards its flatter bottom, though we cannot know for certain whether we have passed the minima and are on the ascent. I would argue that we are, as evidenced by the recent events throughout the Empire. In Morrowind, Lorkhan's heart has been destroyed (liberated?) at the hands of a mysterious reincarnation of the cultural hero Nerevar, Sotha Sil and Almalexia are dead, and Vivec has disappeared after a most unusual trial. In Cyrodiil, the Dragon Fires have been extinguished, the Amulet destroyed, the Septim line broken, and Dagon defeated by Akatosh himself. Subsequently, Umaril Half-Elven returned from the Aether, and was once again banished with the help of Pelinal Whitestrake. This increase in mythological activity, and the rise in awareness of the subject that comes along with it, must mean that we are on the rise towards a greater unity with the divine.

Had this lying around for a while, found it while cleaning up my folders. Thought I'd post.
Its not really a theory, since it doesn't present anything awfully revolutionary. More like a way of visualizing the nature of time. Also an explanation for why Tamriel is so boring now days.
P.S. OMG mah first post on teh new forumz lol
