Answer to Question 1
Gravitational waves are produced in some of the more exotic events found in astronomy. Examples include (1 ) the merger of a binary-star system, (2 ) the collapse of a star into a black hole, and (3 ) the collision of two black holes. Also, a binary system with two neutron stars could produce significant amounts of gravitational radiation. A study of this radiation can tell us much about the physical conditions of these objects and events. They are also predicted by Einstein in his General Theory of Relativity.
