CalTitle1: The maths (and physics) of gravitational waves

Auth: leo@dyn-129-78-251-238.wirelessguest.usyd.edu.au (ltzo2369) in SMS-WASM

The direct detection of gravitational waves has been touted as one of the greatest scientific discoveries. But what are gravitational waves, and how were they detected? Here, I will review the concepts and ideas behind Einsteinâ€™s general theory of relativity, including the notion of space-time, the stuff that does the waving in a gravitational wave. Weâ€™ll also consider the interaction of a gravitational wave with matter, and look at how we deduce that the wave was formed by the collision by two massive black holes.
