The Universe has many extreme events, from the Big Bang onward. In this talk I shall concentrate on extremes of power observed in the Universe, from Solar flares to exploding stars, magnetars, quasars, and the emission of gravitational waves from the merger of black holes. Extremes test our understanding of physics. The most extreme events briefly exceed the power of all the stars in all the galaxies of the observable Universe.
