What are we made up of? What holds material bodies together? Is there a difference between terrestrial matter and celestial matter – the matter that makes up the Earth and the matter that makes up the Sun and other stars? When Democritus stated, between the fifth and fourth centuries BCE, that we are made up of atoms, few people believed him. Not until Galileo and Newton in the seventeenth century did people take the idea seriously, and it was another four hundred years before we could reconstruct the elementary components of matter.
Everything around us – the matter that forms rocks and planets, flowers and stars, even us – has very particular properties. These properties, which seem quite normal to us, are in fact very special, because the universe, whose evolution began almost fourteen billion years ago, is today a very cold environment. In this book, Guido Tonelli explains how elementary particles, which make up matter, combine into bizarre shapes to form correlated quantum states, primordial soups of quarks and gluons, or massive neutron stars. New questions that have emerged from the most recent research are answered: in what sense is the vacuum a material state? Why can space-time also vibrate and oscillate? Can elementary grains of space and time exist? What forms does matter assume inside large black holes?
In clear and lively prose, Tonelli takes readers on an exhilarating journey into the latest discoveries of contemporary science, enabling them to see the universe, and themselves, in a new light.

Industry Reviews
"This book, with its lucid, exhilarating and cultured prose, takes the reader on a grand tour of the cosmos, clearly explaining many of the most profound mysteries of twenty-first-century science along the way. Tonelli, our guide, shows us that from humans to the universe which gave birth to us, nothing is eternal and immutable. We learn that some of the most profound discoveries lie within ourselves and our origins, and we are compelled to agree that matter is a grand illusion. This book is a masterpiece of the genre."
Ian Shipsey, University of Oxford
"Tonelli guides the reader with depth and insight into this fascinating aspect of modern physics: as it celebrates the triumph of materialism, it leads to an understanding of matter profoundly different from, and richer than, the traditional one."
Carlo Rovelli, author of Seven Brief Lessons on Physics
"An extraordinary personal journey through the nature of matter, from its smallest obscurities to its grandest inscrutabilities. Tonelli is a wonderfully informative guide."
Jim Baggott, co-author of Quantum Drama: From the Bohr-Einstein Debate to the Riddle of Entanglement
“what his lively and informative book demonstrates is how much we know about the matter we are made of, and how little we know about the other stuff that constitutes most of the cosmos.”
