The Gravitational Universe
Gravity is the dominant force in the universe. We propose the first ever mission to survey the entire universe directly with gravitational waves, to tell us about the formation of structure and galaxies, stellar evolution, the early universe, and the structure and nature of spacetime itself. Most importantly, there will be enormous potential for discovering the parts of the universe that are invisible by other means, such as black holes, the Big Bang, and other, as yet unknown objects.
The European Space Agency has recently launched the process for choosing candidates for the next large mission launch slots. The first step in this process is the submission of white papers advocating science themes. The eLISA team will submit a compelling science case, which will be addressed by our eLISA mission concept in 2028.
