"Ten thousand years would be even more off. Wrapping one's brain around big numbers is hard--that's how Congress gets away with spending what they do. Few people have a concept of what a million, a billion, a trillion are. Mathematically, one knows they exist, but the implication of the number is often ignored or rejected--perhaps because it's so difficult to picture, it's so far outside the numbers we usually count and experience in some tangible form."Here's a useful rubric I learned in High School (Thank you Mr. Gazeau)
1 thousand seconds = a coffee break
1 million seconds = a vacation
1 billion seconds = A career
1 trillion seconds = 310 centuries
