Data catching Santa in the exploding digital universe!

At this time of year, cynics and sceptics pour scorn on Santa and his faithful reindeer, the prancers and dancers of this festive time. The gauntlet is often laid down as follows. Santa will visit all those children who want presents from him – in about one billion homes – which he has to visit on Christmas Eve.

Thankfully, Fermilabs published the calculations some years ago and proved that Santa, travelling at close to the speed of light, would have no problems covering the ground, in 500 seconds, leaving a generous but fleeting 0.15 milliseconds per dwelling to wolf down some sherry and mince pies. We are of course assuming there is just one Santa, but please note that in Iceland they have 13 Santa Clauses, sons of a horrible mountain hag called Grýla (we leave the re-calculation as an exercise for the reader!).

So what about data? Let’s think not about boring networks and bandwidth, but something more fantastic: the whole of our digital universe.

The Guardian reported back in 2009 that “At 487bn gigabytes (GB), if the world’s rapidly expanding digital content were printed and bound into books it would form a stack that would stretch from Earth to Pluto 10 times.”

Assuming 500bn Gb was being added every 18 months, the speed of the 2009 virtual stack of books was about 1000 kilometres per second. This is fast but well short of the speed of light, that is 300 times this value.

The rate of growth is not constant. It too is doubling every 18 months. It is no wonder this was characterised as the “expanding digital universe”. IDC’s fifth annual study on the digital universe published in June 2011 estimated that we had reached 1.8 trillion gigabytes. We are exploding according to plan!

Translated into a velocity, I have calculated that the exponentially accelerating virtual stack of books, reaching well beyond our solar system, will be travelling at more than the speed of light by 2018. Unlike Santa and crew, our ‘virtual stack’ does not have to comply with the special theory of relativity (Einstein, 1905).

So data will not only catch Santa, but accelerate well beyond him, if we carry on at this rate.

With some thought and some digital out-sourcing, maybe Santa can use this virtual stack as a delivery mechanism, and so create a little space in his busy schedule at this time of year to enjoy the mince pies and sherry at more leisure, and avoid indigestion.

Merry Yuletide.
