The Physical Impossibility of Santa Claus

2013/10/16

For Santa to stop at each house, he would need to maximise his speed between children, to give him sufficient time to deliver presents.
If Santa were to cover the linear distance at the fastest possible speed (the speed of light, 299,792,000 m/s), he could do so in 31 minutes and 53 seconds.
This would give Santa the balance of the 24 hours - 23 hours, 28 minutes and 7 seconds (84,488 seconds) to stop and deliver presents.

Additionally, we need to factor in acceleration.
Let's give Santa 30 minutes to accelerate at the start of Christmas Eve, and 30 minutes to decelerate at the end of Christmas Day.
This leaves Santa with just 23 hours to cover his target distance now, which means he has to average 6,925,640 m/s.
To reach this speed over a 30 minute period, Santa needs a constant linear acceleration of 3,848 metres per second per second, or roughly 392 Gs.
