"The Art of the ""What-If?""" by Nahin, Paul J.;

Long description:

Contrary to popular belief, the goal of science fiction (SF) is not the prediction of the future, but rather to explore the multitude of possible futures. That is, SF is the literature of ‘what-if’ scenarios. This book explores more than a dozen such possibilities, with each chapter ending with a fictional illustration of the theme of that chapter (time travel, topology, alternate worlds, computer intelligence tests for politicians, invisibility, and more). The fictional treatments ask — and sometimes answer — questions like:

⦁ What might happen if you discovered how to induce nuclear fusion in room temperature water?

⦁ Could a combat soldier, and an intelligent, lethal weapon, develop a deep emotional relationship?

⦁ If an archeologist, using x-rays, discovered the lost casket of Jesus in an Egyptian museum, would he open it? If he did, what might he find? (This tale appeared in print two years before the release of Raiders of the Lost Ark.)

⦁ What if you received a letter, addressed specifically to you, from a man who died decades before you were born?

⦁ Could a little boy who tries to fix the family television set save Earth from an interstellar invasion?

⦁ In 1971 ‘D. B. Cooper’ high-jacked a commercial airliner and then bailed-out (with a $200,000 ransom) into a snowstorm and vanished forever. Or did he?

⦁ What might happen if you ate a four-dimensional doughnut?

The stories in this book will challenge your imagination, and perhaps make you wonder ‘Well, maybe that could happen!’
