In this short paper renowned Harvard astrophysicist Abraham Loeb describes with "back of envelope calculation" a possible effect of a gravitational wave originated by a merger of two supermassive black holes in the center of Milky Way galaxy. Such merger would cause a measurable, up to 1 mm permanent increase of the distance between the Earth and the Moon. It would happen because the gravitational attraction between the two bodies would weaken during the time that takes for the wave to cover the distance between them, which is about 1 s.
