Which is insane. When the numbers become too large, they just stop making sense intuitively.
I had a nice comparison to put a billion into perspective : a million seconds is 11 days, a billion seconds is over 30 years. We understand these two durations reasonably well, and the difference can be "felt" clearly.
A trillion seconds is 30000 years... and again, the numbers stop making sense. That would be the Upper Palaeolithic. Agriculture was invented 10000 years ago. Hmm, what else ? Right, sorry, I rounded down. It would actually be 31688 years. A little slip-up of 1700 years, no biggie. The difference between today and the antiquity.
