The Primary Universe Revisited

[stephen]

Hi, I have just watched DD and read TPOTT, and I am now hoping that someone could explain to me how Donnie manages to return the artifact to the Primary Universe.

im probably wrong...but i think when the TU was destroyed, the artifact just returns becuase the TU would have never existed.

im not sure tho.

The jet engine that crashed into donnie bedroom near the begining of the movie is the key to EVERYTHING.
You see, this jet engine came from NOWHERE initially. It's creation was a result of the corruption of the space time continuum. How this corruption occured is not made clear, but one can assume that this type of occurence, although rare, does occur on occasion. Robert Sparrow's book THE PHYLOSPHY OF TIME alludes to this.
This corruption created a paradox in which this engine appeared out of nowwhere and then crashed thru Donnie's bedroom nearly killing him. Since everything in the universe must come from SOMEWHERE, since everything must have a begining and end, the IMPOSSIBILITY of this engine existing caused an instability in the very fabric of the space time continuum, most noticably in the vacinity of Middlesex, Virginia, where the story takes place. From this point on everything that occurs, does so in a TANGENT UNIVERSE. Eventually, according to THE PHILOSPHY OF TIME, this would lead to the formation of a black hole, or a wormhole, which would collapse in upon itself destroying everything.
Now, if Donnie had died in the being of the movie everthing would have continued on like "normal" until the wormhole consumed everything.
HOWEVER, some higher power, be it GOD or whatever, saw this eventuallity and decided to intervene. They awoke Donnie from his slumber so they could use him to put things right.
WHY DONNIE YOU ASK?
Because, quite frankly, Donnie was expendable. He was going to die ethier way, so at least this way, it would not be an empty death.
Donnie purpose was to give this Jet Engine which appeared out of nowwhere, which could be tied to no plane that might have crashed, a reason for existing.
So Donnie, with the abilities granted to him by this HIGHER POWER was able to send sheer the jet engine from plane that his mother was on(that had been maneuvered into position by this higher power), and send it back thru the wormhole to crash into his bedroom back in the Primary Universe.
Now, thanks to Donnie, the Jet Engine had a reason for being, it CAME FROM SOMEWHERE, if even only from a Tangent Universe that no longer existed. Because once the paradox of the engines existence had been resolved, the Tangent Universe dissapeared and the Primary Universe continued on like it always had.
Now, since the Tangent Universe had been eradicated, all but a few lingering memories(or dreams) remained of what had occured(alluded to during the MAD WORLD montage).
So with the knowledge of the Tangent Universe gone, Donnie didnt know what was going to crash thru his bedroom roof, and he was killed.
But one can safely assumed that the Donnie that existed in the Tangent Universe knew what his fate would be, and sacrificed himself for his friends, for his love Gretchen, for this family, for the Universe.
And that is in essence, why he is a HERO and why this MOVE ROCKS!!!!
