Is Einstein Still Right?

Albert Einstein is often viewed as the icon of genius, and his theories are admired for their beauty and correctness. Yet the final judge of any theory is the rigorous test of experiment, not the fame of its inventor or the allure of its mathematics. For decades, general relativity has passed
test after test with flying colors, including some remarkable new tests using the recently detected gravitational waves.

Still, there are reasons for doubt. Einstein's theory of gravity, as beautiful as it is, seems to be in direct contradiction with another theory he helped create: quantum mechanics. Until recently, this was considered to be a purely academic affair. But as more and more data pour in from the most
distant corners of the universe, hinting at bizarre stuff called "dark energy" and "dark matter," some scientists have begun to explore the possibility that Einstein's theory may not provide a complete picture of the cosmos.

This book chronicles the latest adventures of scientists as they put Einstein's theory to the test in ever more precise and astonishing ways, and in ever more extreme situations, when gravity is unfathomably intense and rapidly churning. From the explosions of neutron stars and the collisions of
black holes to the modern scientific process as a means to seek truth and understanding in the cosmos, this book takes the reader on a journey of learning and discovery that has been 100 years in the making.

"[Will and Yunes] succeed superbly in describing the history and personalities ... and work diligently ... to explain the science ... Solid insights into Einstein's dazzling discoveries." -- Kirkus Reviews

"Physicists Will and Yunes take readers on an intellectually challenging but invigorating tour of experiments involving Einstein's theory of general relativity ... A valuable treatise on a foundational topic in modern physics." -- Publishers Weekly

"The two authors have not only the broad spectrum of knowledge and personal experience necessary to master the subject, but also the writing skills needed to provide a fresh and witty narrative that is comprehensible to a wide audience... I strongly recommend it to all those interested in general
relativity." -- Roberto Lalli, Physics Today

"Will and Yunes provide an entertaining overview of the many tests that general relativity has been put to over the past 100 years or so... In fact, the book contains a lot more interesting stuff - and nice personal anecdotes - than the title suggests... the authors strike the perfect balance
between depth and accessibility, using helpful metaphors wherever is necessary." -- Govert Schilling, BBC Sky at Night

"Clifford Will and Nicol�s Yunes are celebrating the effectiveness of the general theory of relativity... a genuinely interesting book." -- Brian Clegg, Popular Science
