Black Hole Blues
Available in Stock
When black holes collide, vast amounts of energy are emitted in the form of gravitational waves. Einstein predicted the existence of such waves in 1916, but not until a century later was it possible to create instruments of sufficient sensitivity to detect them from Earth. Reporting her own conversations with her fellow-astrophysicists, Levin’s lyrical, humorous account of this decades-long quest captures their ambitions and obsessions, struggles and disappointments as they endeavour to measure subtle shifts in the shape of spacetime. Felt-tip mark on lower trimmed edge.
