Tech Info: Technology helps Santa Claus make magic

Ever wondered how Santa Claus can travel around the world in just one night on his reindeer-pulled sleigh and deliver toys to all the children? "He exploits the space-time continuum," says Larry Silverberg, a professor of mechanical and aerospace engineering at North Carolina State University.

Santa’s magic may go far beyond merely traveling across 200 million square miles (322 million sq km) to visit hundreds of millions of homes of believing children in just one night, Silverberg said. "He understands that space stretches, he understands that you can stretch time, compress space and therefore he can, in a sense, actually have six Santa months to deliver the presents," Silverberg told Reuters. "In our reference frame it appears as though he does it in the wink of an eye and in fact there have been sightings of Santa, quick sightings, and that’s in our reference frame, but in Santa’s reference frame he really has six months."
