The universe. Some information to help you live in it.
One: Area. Infinite. As far as anyone can make out
Two: Imports. None. Its impossible to import things into an infinite area, there being no outside to import things in from.
Three: Exports. None. See Imports.
Four: Rainfall. None. Rain can not fall because in an infinite space there is no up for it to fall down from.
Five: Population. None. It is known that there are an infinite number of worlds, but that not everyone is inhabited. Therefore, there must be a finite number of inhabited worlds. Any finite number divided by infinity is as near to nothing as makes no odds. So, if every planet in the universe has a population of zero, then the entire population of the universe must also be zero, and any people you may actually meet from time to time are merely the products of a deranged imagination.
Six: Monetary Units. None. In fact, there are three freely convertible currencies in the universe, but the Altairian Dollar has recently collapsed, the Flainian Pobble Bead is only exchangeable for other Flainian Pobble Beads, and the Triganic Pu doesnt really count as money. Its exchange rate of six Ningis to one Pu is simple, but since a Ningi is a triangular rubber coin six-thousand, eight-hundred miles long each side, no one has ever collected enough to own one Pu. Niginis are not negotiable currency because the Galactic Banks refuse to deal in fiddling small change. From this Basic premise its very simple to prove that the Galactic Banks are also the products of a deranged imagination.
Seven. Sex. None. Well - actually, there is an awful lot of this. Largely because of the total lack of money, trade, banks, rainfall, or anything else that might keep all the nonexistent people in the universe occupied. However, its not worth embarking on a long discussion of it now, because it really is, terribly complicated. For further information See Chapters Seven, Nine, Ten, Eleven, Fourteen, Sixteen, Seventeen, Nineteen, Twenty-One to Eighty-Four inclusive, and
most of the rest of the book. Its largely, on the account of passages like this, that the book of The Hitch-Hikers Guide to the Galaxy is being revised by Ford Prefect and Arthur Dent. Unfortunately, they are being presented with too many distractions to be able to settle down to doing any solid research. Not only does Arthur Dent still have to find the Question to the Ultimate Answer of Life, the Universe, and Everything, but the newly-stolen spaceship is currently behaving rather like this:
