The Last Question – Isaac Asimov
First up on our list of the best sci-fi short stories is Isaac Asimov’s classic work, The Last Question. This tale spans billions of years and follows humanity’s evolving relationship with a supercomputer known as Multivac. Across a series of conversations, different generations ask the same seemingly impossible question: can the universe’s inevitable increase in entropy – and ultimately its heat death – be reversed? Each time, the computer responds that there is insufficient data to provide an answer.
As humanity expands beyond Earth, merges with technology, and eventually transcends physical existence, the question remains unanswered. The story steadily broadens its scope from everyday human concerns to the fate of the whole cosmos, culminating in one of the iconic endings in science fiction. Blending hard science with profound philosophical ideas, The Last Question delves into humanity’s enduring curiosity, the pursuit of knowledge, and our longing to overcome even the most fundamental limits of existence.

This awareness of what lies ahead of us is an essential aspect of being human. But how much more would we want to know?

The government, which learned of the Jaunt through its inventors’ use of a computer database in their experiments, soon took control of the project, demoting the scientist to a figurehead in the program.

Due to environmental pollution, water became a more expensive and profitable commodity than oil.
