Physics of the Impossible

Interesting Facts

• The book explores various concepts once considered science fiction and analyzes how they might become reality in the future.
• Michio Kaku divides impossible technologies into three categories: Class I, Class II, and Class III, depending on how feasible they are in the near or distant future.
• Class I includes technologies that do not contradict known laws of physics and could be realized in the coming decades or centuries, such as teleportation and invisibility.
• Class II covers technologies that are on the edge of our knowledge and might be realized in thousands or millions of years, like time travel and interstellar ships.
• Class III includes technologies that violate known laws of physics and may be impossible, such as perpetual motion machines and predicting the future.
• The book considers the possibility of creating force fields that could protect against bullets and other threats, explaining how this might be achieved using plasma and magnetic fields.
• Michio Kaku discusses the concept of telepathy and its potential realization through advanced technologies like brain scanning and neural interfaces.
• The book also touches on the topic of antigravity and examines how devices could be created to counteract gravity using exotic forms of matter or energy.
