It is almost the first inhabited region on the planet where Christmas arrives, being 14 hours ahead of us here in Ireland. This allows Santa to get a head start on his busiest day of the year.
Contrary to popular belief, Santa’s sleigh actually executes a polar orbit around Earth, so that every 90 minutes the sleigh’s contents can be topped-up by the elves at the North Pole. Otherwise there might just be too many presents for the poor reindeer to pull in one go.

In fact, some scientists have suggested that Santa uses even more physics know-how to deliver his presents efficiently. Roughly speaking, according to the theory of quantum mechanics developed by Erwin Schrodinger (who lived on Kincora Road in Clontarf , Dublin for 17 years) and Werner Heisenberg, the more precisely you know the position of something, the less precisely you know its speed.
Because Santa is travelling very quickly to be able to deliver his presents to about 2 billion (good) children, according to the theory of quantum mechanics, this means he could theoretically be everywhere at once, delivering his presents simultaneously.

However, if a single child spotted him, his location would be known exactly and no more presents could be delivered this way.
Last month we saw the first landing of a man-made object on a comet. However, Santa has the technology to not only land on a comet, but also to bring some of it back to earth.
Scientists believe that comets delivered water to the earth in the early life of the solar system. Comets are sometimes referred to as ‘dirty snowballs’ because they are made of a mixture of ices, soot and dust.
Sometimes Santa works his magic to bring some comet snow back to earth. Will it be our turn for a white Christmas this year?

Satellite technology, such as global-positioning systems, allows children to keep an eye on Santa’s progress on Christmas Eve.
It is all thanks to NASA, the American space agency, and NORAD, a joint American and Canadian organisation that tracks airplanes, missiles and space launches.
On December 24, they spring into action the moment their radar alerts them to Santa’s departure from the north pole. Their technology allows them to get a fix on where Santa is at any time in his whirlwind journey.
The satellites, at 22,300 miles above the Earth, have infrared sensors that can pick up Rudolph’s red nose and they also receive up-to-date information from SantaCams, high-speed cameras that are pre-positioned at many places around the world.
