PPT-Observing the Universe with Gravitational Waves

Thursday October 13 700 PM Bell Museum Auditorium This event is free and open to the public and will be followed by telescope observing About the talk Advanced LIGO gravitationalwave detectors recently recorded the first signals coming from mergers of binary black hole systems marking the beginning of gravitationalwave astronomy and astrophysics For the first time we are able to observe and study the universe with gravitational waves and to learn about objects never observed before.

In 1916, the year after the final formulation of the field equations of general relativity, Albert Einstein predicted the existence of gravitational waves. He found that the linearized weak-field equations had wave solutions: transverse waves of spatial strain that travel at the speed of light, generated by time variations of the mass quadrupole moment of the source [1,2]. Einstein understood that gravitational-wave amplitudes would be remarkably small; moreover, until the Chapel Hill conference in 1957 there was significant debate about the physical reality of gravitational waves [3] Sources and detection .
