**( More Details )**

**The list so far:**

I HAVE NO IDEA, BUT I'D LIKE TO USE THEM IF I CAN FIGURE OUT AN APPROXIMATION:

* The approximate number of primes between 0 and 2^57,885,161 − 1 (???)

* If two 'opponents' at Go are actually collaborating to make the game as long as possible, approximately how many turns might the game last (on a 19x19 board)? (???)

* The approximate number of different chess games for which the board never returns to a previously experienced state. (???)

* The approximate number of atoms in everything living on the earth (???)

I THINK THESE ARE RIGHT:

* The approximate circumference of the earth in miles (~10^4)

* The approximate number of sheets of paper in a stack as tall as the height of the Transamerica Pyramid in SF (~10^6)

* The approximate number of seconds in a human life (~10^9)

* The approximate number of people in the world right now (~10^10)

* The approximate number of neurons in a human brain (~10^11)

* The approximate number of seconds between now and when a dinosaur last lived (~10^15)

* The approximate number of ants in the world right now (~10^16)

* The approximate number of calculations that can be done by the world's current fastest computer (The Tianhe-2 supercomputer) in 1 minute (~10^18)

* The approximate number of stars in the universe (~10^30)

* The approximate number of atoms in the earth and everything on it (~10^50)

* The approximate number of different ways a deck of 52 cards might be shuffled (~10^68)

* The approximate predicted number of atoms in the universe (~10^80)

* The approximate number of rabbits that would exist in the universe after a year if, starting with 2 rabbits, ever day, every pair of rabbits alive mate and produce 6 offspring, and no rabbits ever die. (~10^219)

* The approximate value of the largest known prime number (~10^17425169)
