We have long understood black holes to be the points at which the universe as we know it comes to an end
- mysterious chasms so destructive & unforgiving that not even light can escape their deadly power. Recent research however has led to a cascade of new discoveries that have revealed an entirely new & crucially important side to black holes. Super-sized versions often billions of times more massive than the Sun lurk in every galaxy in the universe. & these chasms don't just vacuum up everything around them; they also spit out huge clouds of matter & energy. In Gravity's Engines" renowned astrophysicist Caleb Scharf reveals how these giant black holes profoundly rearrange the cosmos that surrounds them controlling the number of stars in the galaxies & in turn the entire universe. With lucidity & elegance Scharf traces the two hundred year history of our attempts to discover the nature of black holes from an English academic turned clergyman in the late 1700's who first identified these 'dark stars' to Einstein & the great revolutions of relativity & quantum mechanics. Engaging with our deepest questions about our origins he takes us on an intimate journey through our endlessly colourful universe revealing how the cosmic capacity for life is ultimately governed by
- & perhaps could not exist without
- black holes."
