Rating: ★★★☆☆
Michio Kaku achieves a difficult goal in this book: bringing to the general public concepts that often seem reserved only for theoretical physicists. Through an engaging style full of references to popular culture (film, comics, and science fiction), the author takes us on a fascinating journey exploring whether what we call “impossible” is truly an insurmountable limit of science or merely a temporary frontier.
One of the book’s great strengths is its classification of “impossibles” into three levels, which makes it easier to understand the distance between ideas that today seem like magic (such as invisibility or teleportation) and those that could become viable future technologies. His ability to connect imagination with scientific research makes the reading both stimulating and optimistic.
However, the book suffers from a certain degree of repetition and, at times, sacrifices depth in favor of lighter popularization. Readers looking for a more rigorous technical analysis may miss more mathematical or experimental details. Kaku tends to simplify and sometimes leaves too much room for speculation.
Overall, it is a recommended book for those who want to open a window into the future of science without requiring advanced knowledge. It is not an academic treatise, but rather an invitation to dream with one’s feet grounded in present-day physics.
Cover
The cover uses an Istockphoto image that perfectly matches the spirit of the book: an invisible human figure leaving only the clothes visible in motion. The sense of absence and, at the same time, dynamism conveys, at a glance, the central idea of the work: exploring the limits of what we consider possible. The neutral colors highlight the title in vivid tones, giving it a modern and scientific visual appeal. It is a well-chosen, evocative cover that remains faithful to the book’s content.
