Buonanno and Damour present the field of gravitational-wave astronomy, opened in 2015, 100 years after Einstein’s theory of General Relativity, when gravitational waves were first observed using laser interferometers.
This paper deals with the period that reaches from Einstein’s discovery of the theory of general relativity to the development of accurate analytical descriptions of the gravitational-wave (GW) signal emitted by binary systems composed of compact objects. In November 1915, Albert Einstein finalized the construction of the theory of general relativity. General relativity is both a new theory of the structure of space-time (generalizing Einstein’s 1905 theory of special relativity), and a new theory of gravitation (generalizing Newton’s 1687 universal law of gravitation). Einstein’s theory of general relativity revolutionized the basic physical concepts of space, time, and matter, and led to the introduction of new physical objects, notably gravitational waves, black holes, and cosmological space-times.
