How does Santa do it? Science of course!

All those presents, all those kids, how does Santa do it? North Carolina State University’s Dr. Larry Silverberg, a professor of mechanical and aerospace engineering let’s in on Santa’s secrets to getting what seems impossible done in one night.
According to Dr. Silverberg, Santa uses nanotechnology to miniaturize the presents (solving the problem of the bulk) along with what he calls “relativity clouds” which bend time and space to allow Santa the needed time to visit all those homes. What seems like a blink of the eye to us outside the cloud, is months to Santa and his trusty team of reindeer.
Still, reindeer are equipped with jet packs to increase their speed. Dr. Silverberg is a aerospace engineer after all. The naughty vs. nice tracking is done with a powerful listening network.

Dont forget, NORAD will get in on the Santa business again this year with their Santa Tracker. I’m going to tag this with “manned spaceflight” for obvious reasons.

The Twin Rectangular Jet model, installed on the Nozzle Acoustic Test Rig in the Aeroacoustic Propulsion Laboratory at NASA's Glenn Research Center being tested.
The Twin Rectangular Jet model, installed on the Nozzle Acoustic Test Rig in the Aeroacoustic Propulsion Laboratory at NASA's Glenn Research Center, is being tested to determine the acoustic impact of engine configurations on low sonic boom aircraft for the High Speed Project of the Fundamental Aeronautics Program. The High Speed Project is a multi-center effort to develop and test the technologies of a new generation of aircraft that can fly at supersonic speeds. Glenn's research involves predicting the airport noise of these novel aircraft by examining innovative airframes and propulsion integration that are different from the conventional tube-and-wing aircraft observed at commercial airports. Inside the aeroacoustic dome, this generic, low-fidelity aircraft engine exhaust model features twin rectangular nozzles. Researchers are investigating the impact of having the propulsive exhaust come from the slot nozzles atop the aircraft. Testing the proposed components of these high- speed aircraft will help manufacturers meet the noise standards required around the nation's airports. Image Credit: NASA/Bridget R. Caswell
