At an innocent ten years old, I asked mom, "but how fast would Santa have to travel to go to each house in one night?"
Good question, Esteban.
In layman terms, Santa's existence is disproved when considering the amount of energy and speed needed to stop and go around the planet. To my knowledge as an ten year old, I realized, through research, that the jolly ol' Santa would be traveling at an approximate 1,800 miles per second with 32 hours to check off the world's Christmas list.
But how about stopping at each home? Well, considering that the amount of energy needed to go from 6,480,000 mph to 0 mph in a small amount of space would likely create a black hole, stopping is not necessarily an option.
Alas, Santa will somehow defy physics this up coming Christmas and indulge in millions of pounds of cookies and milk—yes, he is also immune to type 2 diabetes.
