Why not take this into Science Fiction?

I know better than to have too high expectations when staring at the fireplace on Christmas Eve, but there will always be that passion to put as much logic as possible into the aspects of Santa's legend. So with some help from some science fiction precedence, I put together theories.
 
 
 
***Santa's making his way through the chimney/no chimney***  Like you see on this movie--teleportation.
 
 
 
***Reindeer flying***  Santa has nuclear physicists who've pinned down the technology of 'gravitons' and animal geneticists who have combined that into gene splicing in breeding the reindeer.
 
 
 
***The Whole World All in One Night***  For starters, it's more appealing to believe that Santa takes just the United States as his jurisdiction, since most other countries have their own different version of Santa (Pere Noel, Father Christmas, etc.), but not a huge quibble.  For several years I wanted to fall back on the explanation given in "The Night they Saved Christmas" in which Santa had a "Time Deceleration Device" (TDD), but that became too awkward when I realized that Santa would have to stretch (rough estimate) one night into two years to deliver to all the kids in the U.S. alone. so I came to the conclusion that along with using the TDD, Santa has a MAD, "Motion Acceleration Device" and that has him traveling from community-to-community, house-to-house, and apartment-to-apartment at a blurred speed.  Still, it wouldn't feel right if Santa didn't occasionally give a little extra time to a few kids sleeping on the living room couch in front of the tree as often seen on TV and movies, so Santa picks a few houses where he'll do that, putting the TDD in 'extra slow' mode, based on the special needs of a kid Santa feels could benefit the most from with that extra time.
 
***Too many Presents to Deliver***  Santa of course has his HUGE, HUGE, HUGE, HUGE stockpile of gifts at the North Pole.  Each item is slapped with a signal chip that is digitally linked to a teleportation device that materializes into Santa's big bag whenever he reaches its designated residence.
