There were a few blogs I spotted recently who were asking the question, 'how many zeroes in a billion'? They then listed several examples, such as Jesus died a billion minutes ago', designed to give some sort of perspective to the enormity of the number one trillion. A number we see increasingly often in these financially turbulent times.
At the time I remembered a video that gave a graphic representation that seemed to do the job so much better. I couldn't find it then but I stumbled upon it it today. See for yourself what a truly massive number a trillion really is.
