The Last Question - Isaac Asimov

"The Last Question" follows humanity's desperate attempts to reverse the universe's inevitable heat death, spanning trillions of years across countless civilizations. At each stage of cosmic history, people pose the same question to increasingly powerful computers: can entropy be reversed? The story stretches from the first fusion reactors to the final moments of existence itself, where humanity becomes one with the machines they created. Asimov weaves together themes of technology, faith, and the limits of knowledge into a narrative that expands in scope with every chapter. The ending delivers one of science fiction's most celebrated twists, reframing everything that came before.
