Making the Earth Ripple: Black Holes and Gravitational Waves
Talk Abstract: Einstein's relativity theory predicted both the existence of black holes and gravitational waves. At the time both were thought to never be observable. The discovery of actual black holes began in the 1960's and BH's are now known in many places in our universe. Detection of gravitational waves requires extreme precision of measurement, and only in the last year has it been possible to measure these slight ripples in space-time. We will discuss the method by which these waves have been (finally, after 20 years of effort) detected twice in the past year. Also we will include a brief discussion of black holes, since the events producing gravitational waves involve merging black holes.
