The Architecture of the Cosmos

In the first part of the book, I discuss the discovery of gravitational waves and the birth of multimessenger astronomy. Borrowing the structure of Dante’s Paradise and Inferno, I illustrate the biggest mysteries of modern cosmology and argue that multimessenger astronomy, and in particular gravitational waves, may hold the key to unlock these mysteries, and may thus help a bridge between the realm of gravity, and that of quantum physics. Stars. Black holes. Galaxies. Even the most well-known celestial objects are so removed from our daily experience that we might almost mistake them for abstract entities. Yet they are no less real than the objects that surround you as you read these lines.
