Quote by Douglas Adams, The Original Hitc
It is known that there is an infinite number of worlds, but that not every one is inhabited. Therefore, there must be a finite nuber 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 populations 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.
Summary
This quote ponders the existence of inhabited worlds among the infinite number of worlds that potentially exist. It suggests that the presence of finite inhabited worlds implies that the overall population of the universe must be finite as well. Furthermore, it whimsically proposes that if every planet in the universe is devoid of life, any encounters with people are merely illusory and figments of an eccentric imagination.
