Look at a thing in motion and ask what moves it. Then ask what accounts for that mover. Follow the question and the chain begins to fall away beneath you. Aristotle did not rescue himself by inventing a first morning: in Physics VIII, motion has always existed. His abyss was different. If every mover can only borrow motion from another, what holds the moving world up now?

Aristotle solved the problem by positing an entity that causes motion but is itself immobile. This 'unmoved mover' does not push the universe like a mechanic. It pulls it — the way a destination pulls you toward it. Aristotle called this a final cause: not a shove from behind, but a perfection being aimed at. By being the thing all other things move toward, it sets the stars spinning without ever lifting a finger.

Two questions are often folded into one: When did the universe begin? and What explains motion or order at all? Aristotle's cosmos had no first temporal domino. His unmoved mover was the anchor beneath an eternal chain, not an event before every event. Call it a 'first cause' and the distinction almost disappears. Keep it visible and the older question returns, still open: what can be first without ever happening first?

First need not mean earliest. In Metaphysics XII, the unmoved mover draws motion as an object of desire—as the destination moves the traveller—without delivering an initial shove. The image is stranger than a row of falling dominoes: an end pulling on an eternal present. Physics does not certify that vision. It does not erase the question inside it either.
