You contradict yourself, Nuke. You claim no edge in one sentence but in the other you state "based on the time since the Universe started". To be able to start implies finite limits, borders, edges, etc, necessarily. Only a finite object with borders and surface can start. A car can start as it is such an object. Do you claim the Universe is such an object? To start as the Universe implies to initiate all motion of all objects in existence all at once. That is logically impossible and is right against the first law of thermodynamics. Impossible and irrational proposition. The motion is being conserved only by that law, not ever started, finished, destroyed or created.
