Space Time Physics

This book invites you on a journey through the most misunderstood concept in all of science — the vacuum. From the earliest philosophers terrified of emptiness to the modern physicists who discovered that “nothing” is a swirling ocean of energy and possibility, this is the story of how the void became the foundation of everything. We begin with the ancient debates about ether and the first laboratory vacuums of the Renaissance, then move through Einstein’s curved spacetime, quantum field theory’s restless vacuum, and the mysterious Higgs field that gives matter its mass.
