We have long understood black holes to be where the universe as we know it comes to an end - huge bodies so destructive that not even light can escape their deadly power. In Gravity's Engines, however, renowned astrophysicist Caleb Scharf reveals an entirely new, and crucially important, side to these mysterious chasms.

The latest research has located super-sized black holes, often billions of times more massive than the Sun, which have the power to rearrange the cosmos and control entire galaxies of stars. Engaging with our deepest questions about our origins, Scharf shows how, without these black holes, life in the universe could not exist.
