| Abstract | The first direct detection of the gravitational waves by LIGO opens the era of "gravitational astronomy". Precise identification of the cosmological source of the LIGO event has been made possible by years of the development of numerical algorithms for the description of strong gravity phenomena. One, however, does not need the power of a supercomputer to figure out what kind of catastrophic event generated the signal observed by LIGO. In this talk I will show how a simple back-of-an envelope analysis reconstructs it with an amazingly good accuracy. |
