Well, at least to me anyway. Saw this today and I thought it was an excellent demonstration of just how big a number a "trillion" is: To get a sense of the enormity of what a trillion is, consider that a million seconds ago was last week, a billion seconds ago was early 1994, the same year O.J. Simpson was arrested for murdering Nicole Simpson and Ron Goldman and a trillion seconds ago it was around 30,000BC, when Neanderthals shared the planet with homo sapiens.
