I am the singularity of Christmas future.

I may have been wrong about Santa/Krampus/St. Nick. I'll be big about it and admit that while I've predicted that he will be the disease vector which will end the human race, or his apparently anti-matter powered sled, radioactive reindeer or just plain obscene levels of danger involved in having a 250 lbs mass moving through your house at something like 0.2 c at some time Christmas eve would spell the end of civilization as we know it. I've gone so far as to advocate building a bunker and hiding deep under the earth on the night of terror. As it turns out, I may have spoken prematurely.

I have now come to believe that there is a serious danger of SantaGheddon in the form of a black hole with earth as the starting mass. As the population of the earth increases, the odds of this year being the one,  the year when at some point a singularity forms and obliterates every little boy and girl, along with everything else made of matter in the general vicinity of earth. No no, the mass of the extra people has nothing to do with it (we're made of stuff that's mostly already here on earth anyway, the extra population is mostly about shifting the balance between soil and ambulatory meat sacks a.k.a. "babies" which eventually turn back into soil, but not before generating at least 1.5 copies)

The problem I see looming, threatening the existence of all life on earth has more to do with something as fundamental as the reason matter has mass. I'll get to how a relativistic Santa/Toymass could mean our doom in a moment, but first some fundamental basis borne of the standard model. 

I'm not going to launch into a description of the standard model here, much as I know you would like one. Click on the link if you're interested in trivialities like "how the universe works" or "real stuff." Stay tuned here if you want to know how the Jolly Red Menace is likely to collapse all of the matter in our vicinity into a gravity well so deep, Timmy and Lassie, mamma Ruth and the entire Martin family will be consumed with nary even a bark of despair escaping.

OK, I'm exaggerating. The actual phenomena as an observer moving past a spherical symmetric gravitating object (or "Earth", as we like to call it) at close to the speed of light is called the Aichelburg–Sexl ultraboost. Seen as a sequence of smooth Lorentzian manifolds; space curves along the axis of symmetry which resolves as a Dirac delta as acceleration approaches c, thus resolving relativity rather nicely and NOT creating an inescapable event horizon.

On the other hand, as Santa's relative speed with respect to the earth increases based on the number of places he must visit (additional population) and his rest mass is increased by the additional number of toys he must pack onto the sled, his relativistic mass density becomes a very very large number. Eventually, the resistance of the atmosphere as he travels at such speeds near the surface will turn the atmosphere into a glowing plasma, while his energy density and momentum increase to the point where the resistance to changes in direction and stresses to the Higgs field in the local area are likely to make this region of space uninhabitable for a while. Presumably, he's shedding mass at a pretty rapid rate, as he infiltrates homes of good girls and boys & dumps presents, but his initial mass and required velocity to visit each home in one night will eventually catch up with us all. All that, and I'm completely ignoring what happens when he tries to slow down from that speed in any reasonable time to start making his evil plans for the next year, imagine how hot your brakes get when you stop your car while driving down a hill. Now multiply that heat by Santa's relativistic mass density including the sled, reindeer and toys. Can you say nova? Huh, not on December 26th you can't, as you'll be an expanding ball of plasma.

I have a plan to help, but first I need to convince some friends at the LHC to place a chimney in _just_ the right place.
