This Very Short Introduction tells you everything about 'nothing' - it is the story of how scientists have been puzzled by the physical problem of what remains when you take all the matter away.
A lively and stimulating guide, taking the reader from ancient ideas and cultural superstitions about the void, via the theories of Newton and Einstein, to the frontiers of current research in today's powerful particle accelerators
Reveals how the vacuum is far from being empty - that in fact it seethes with particles that spontaneously erupt into being - and how this provides fascinating clues about how the universe began, and what was there before
Tells the tale of the mysterious 'aether' that was long ago supposed to permeate the void - how Einstein did away with it, and how the latest research into the 'Higgs field' may mean it is making a comeback
Asks fascinating questions such as: Would nothing exist if there was no one to observe it? Where did everything come from? What lies outside the universe, and what is it expanding into?
What is 'nothing'? What remains when you take all the matter away? Can empty space - a void - exist? This Very Short Introduction explores the science and the history of the elusive void: from Aristotle who insisted that the vacuum was impossible, via the theories of Newton and Einstein, to our very latest discoveries and why they can tell us extraordinary things about the cosmos.
Frank Close tells the story of how scientists have explored the elusive void, and the rich discoveries that they have made there. He takes the reader on a lively and accessible history through ancient ideas and cultural superstitions to the frontiers of current research. He describes how scientists discovered that the vacuum is filled with fields; how Newton, Mach, and Einstein grappled with the nature of space and time; and how the mysterious 'aether' that was long ago supposed to permeate the void may now be making a comeback with the latest research into the 'Higgs field'.
We now know that the vacuum is far from being empty - it seethes with virtual particles and antiparticles that erupt spontaneously into being, and it also may contain hidden dimensions that we were previously unaware of. These new discoveries may provide answers to some of cosmology's most fundamental questions: what lies outside the universe, and, if there was once nothing, then how did the universe begin?
