Gravitational Waves

How Einstein's Spacetime Ripples Reveal the Secrets of the Universe

Brian Clegg
New Paperback

Postscript summary

Although predicted by Einstein’s general relativity, it was not until 2015 that gravitational waves – ripples in space and time – were first detected. This accessible introduction to their discovery explains how the technology required to record movements 100 times smaller than the nucleus of an atom was developed, and how, with their ability to travel through barriers that stop light, the waves offer a new way to investigate the universe.
