First direct detection of a gravitational wave

On 14 September 2015 gravitational waves have been detected for the first time by the two LIGO detectors in Hanford, Washington, and Livingston, Louisiana US. The strong signal was generated by the collision of two black holes 1.3 billion years ago. I will present the discovery giving first an introduction to the gravitational waves physics and methods of their detection.
