Physics of the Future

About the book

In Physics of the Future, Michio Kaku opens a window onto the century already taking shape in today’s laboratories. Drawing on interviews with more than three hundred scientists, he follows technologies that could transform civilisation by 2100: invisible computers embedded in our surroundings, artificial intelligence, molecular medicine, nanotechnology, new energy sources, space travel and unprecedented forms of wealth and social organisation.

The future emerging from these pages is not fantasy detached from science. It is a projection grounded in Nature’s known laws and existing prototypes: internet-connected contact lenses, driverless cars, increasingly autonomous robots, laboratory-grown organs, sensors capable of detecting disease before symptoms appear, smart materials, clean energy, space elevators and machines bringing humanity closer to powers once attributed to gods.

But Kaku does not simply celebrate technology. He also reveals its ambiguity: science is a double-edged sword, capable of liberating, expanding and healing, but also of intensifying inequalities, conflicts and planetary risks. A profound question runs through the book: what kind of humanity will we become when we hold tools capable of reshaping body, mind, life and the planet itself?

Physics of the Future is an immersive journey through the next hundred years: a scientific map of civilisation in formation, where readers see the smart city light up, medicine enter cells, the mind reach towards machines, Earth become a planetary civilisation and space cease to be a boundary and become humanity’s next horizon.
