摘要：
Gravitational waves have been directly detected and astronomical observations indicate that our Universe has a positive cosmological constant.. Nevertheless, a theoretical gauge-invariant notion of gravitational waves arriving at infinity (escaping from the space-time) in the presence of a positive. has been elusive. We find the answer to this long-standing gravitational puzzle and present a geometric, gaugeinvariant radiation condition at infinity.
