SUMMARY:Einstein's Waves: Cosmic Sounds from Black Holes and Neutron S
 tars\, Whitord Public Talk Astronomy \, Vicky Kalogera\, Northwestern 
 University
DESCRIPTION:For the first time\, scientists have observed ripples in t
 he fabric of spacetime called gravitational waves\, arriving at the ea
 rth from cataclysmic events in the distant universe. These recent obse
 rvations confirm a major prediction of Albert Einstein’s 1915 genera
 l theory of relativity and open an unprecedented new window onto the c
 osmos. Gravitational waves carry unique information about their dramat
 ic origins and about the nature of gravity that cannot otherwise be ob
 tained. Detected gravitational waves were produced during the final fr
 action of a second of the mergers of two black holes but also during t
 he last hundred seconds of the collision of two neutron stars. The lat
 ter is the first ever cosmic event to be observed both in gravitationa
 l waves and in electromagnetic waves\, shedding light to several longs
 tanding puzzles\, like the production of gold in nature and the physic
 s origins of brief gamma-ray flashes. I will review the beginnings of 
 this exciting field of cosmic exploration and the unprecedented techno
 logy and engineering that made it possible.
