Description
Book SynopsisThe vacuum is central to physicists'' best theories of subatomic particles, gravitation, and cosmology. Nothingness provides the reference point with which to compare new particle creation and annihilation. Cosmologists use empty universes to study the causal structure of spacetime. Paradoxically, our best physical theories of particles, gravity, and spacetime are theories of nothingness. Stranger still, the physicists'' vacuum is a hive of activity. Quantum fluctuations fill empty space with particles, and astronomers measure gravitational waves, the vibrations of empty spacetime itself.More than Nothing uses the history of the vacuum to show how technical concepts in physics are made real through everyday practice. It provides new insight into the development of twentieth-century theoretical physics through sustained analysis of understudied figures including John Wheeler''s geometrodynamics and Sidney Coleman''s false vacuum. It reveals the surprising influence on physicists from th
