Author: Jesselyn Cook
In “The Quiet Damage,” Jesselyn Cook tells the riveting story of five families shattered by pernicious, pervasive conspiracy theories, and how we might set ourselves free from a crisis that could haunt American life for generations.
Brilliantly researched and beautifully written, the book lays bare how we have been taken hostage by grifters peddling lies — and how we might release our loved ones, and ourselves, from their grasp.
General relativity has entered a new phase of its development as technical advances have led to the direct detection of gravitational radiation from the merging of single pairs of stellar-sized black holes.
The exquisite sensitivity of pulsar signal timing measurements has also been exploited to reveal the presence of a background of gravitational waves, most likely arising from the mergers of supermassive black holes thought to be present at the center of most galaxies.
This book demonstrates how general relativity is central to understanding these and other observations.
