When you try to send it back in time to interfere with itself, the probability of success diminishes to zero the closer you get to possible interference.
For a long time I've held that quantum theory, despite its dominant correlationist interpretation, is deeply congruent with OOO. To "observe" or "measure" at that scale means "to deflect with another quantum." The quantum to be measured is withdrawn.
But this is an even tighter loop. Here a quantum is trying to interfere with itself.
That it can't do so resembles the ontological gap between an object and an intentional object (Husserl), or between an intentional object and an act that studies that object (Husserl), or between the I of enunciation and the I of the enunciated (Lacan).
