The Last Question
by Isaac Asimov © 1956

The last question was asked for the first time, half in jest, on May 21,

2061, at a time when humanity first stepped into the light. The question
came about as a result of a five dollar bet over highballs, and it happened
this way:

Alexander Adell and Bertram Lupov were two of the faithful attendants of
Multivac. As well as any human beings could, they knew what lay behind the
cold, clicking, flashing face — miles and miles of face — of that giant
computer. They had at least a vague notion of the general plan of relays
and circuits that had long since grown past the point where any single
human could possibly have a firm grasp of the whole.

The head of the Galactic
Confederation (76 planets around
larger stars visible from here)
(founded 95,000,000 yrs ago, very space opera)
solved overpopulation (250 billion
or so per planet — 178 billion on
average) by mass implanting.
He caused people to be brought to
Teegeeack (Earth) and put an H Bomb
on the principal volcanoes (Incident 2)
and then the Pacific area ones
were taken in boxes to Hawaii
and the Atlantic Area ones to
Las Palmas and there “packaged.”
His name was Xenu. He used
renegades. Various misleading
data by means of circuits etc.
was placed in the implants.
When through with his crime Loyal Officers
(to the people) captured him
after 6 years of battle
and put him in an electronic
mountain trap where he still
is. “They” are gone. The place (Confed.)
has since been a desert.
