This book consists of seven stories in which fantastic and science fiction themes are addressed, such as the origin of life on planets, time travel, the application of nanotechnology to medicine or genetic determinism. Most of the stories are based on real scientific basis because they are inspired by research that in the not so distant past would have been considered fantasies of science fiction writers . Man has achieved a spectacular degree of technological development over the past two centuries, but nothing compared to what is to come.
