Beschreibung des Verlags
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.
PUBLISHERS WEEKLY
Physicists Will (Theory and Experiment in Gravitational Physics) and Yunes take readers on an intellectually challenging but invigorating tour of experiments involving Einstein's theory of general relativity. Despite the title's question mark, they write in the preface that "general relativity has passed every experimental test to which it has been subjected," so their concern is less with grappling with Einstein's theory itself than with explaining the various methods used to verify it. Some are familiar, such as black holes and gravitational waves, while others, like the "Shapiro time delay," a delay observed in radio waves traveling around the sun, or geodetic precession, the change in the axis of spin of a gyroscope traveling past a massive gravitational body, are less so. The authors put in yeomanlike work to explain each concept, and avoid using any mathematical formulas, other than the unavoidable E=mc . They also provide observations on the scientific process in general and on their own scientific careers (Yunes admits his initial inspiration came from reruns of Star Trek: The Next Generation.) The topic will still stretch the comprehension of general readers, but for those able to soldier through, this will be a valuable treatise on a foundational topic in modern physics.
