HOW does Santa deliver presents worldwide, slithering his bulging bulk down narrow chimneys? Einstein had the answer. Dr Katy Sheen from Exeter University in the UK calculated that Santa & his reindeer need to travel at about 10 million km/ hour to deliver presents to every child celebrating the occasion in a 31 hour period, taking into account different time zones.
Using Einstein's theory of special relativity, objects travelling at high speed become compressed in size - meaning the jolly man would shrink, allowing him to slip down all those chimneys.
He is also able to move around without being spotted because light waves get squashed at high speeds. And we're talking really high speeds - Father Christmas would need to be moving 200 000 times faster than Usain Bolt!
