Hi, I need a beginner's book to study gravitational waves by myself. I am an undergrad physics major and just took my GR course. A beginner's book on GR will also help me lot. please suggest
Gravitational waves are ripples in the fabric of space-time, caused by the acceleration of massive objects, such as black holes or neutron stars.
Gravitational waves were first predicted by Albert Einstein in his theory of general relativity in 1915. He theorized that the acceleration of massive objects would create ripples in space-time.
Gravitational waves are detected using sensitive instruments called interferometers. These instruments measure tiny changes in the distance between objects caused by the passing of a gravitational wave.
Studying gravitational waves can provide insights into the behavior of massive objects and the structure of space-time. It can also help us understand the origins of the universe and the processes that shape it.
In 2015, the Laser Interferometer Gravitational-Wave Observatory (LIGO) made the first direct detection of gravitational waves, confirming Einstein's theory. Since then, new advancements in technology have allowed for more precise measurements and the detection of additional gravitational wave events.
