Description
The gravitational interaction has been widely observed and tested for centuries; as far as we know, it is described with great accuracy by the general theory of relativity. However, these observations only probed and tested the weak-field regime of gravity, in which the beautiful non-linear structure of general relativity plays a marginal role.
Many open questions then arise: how does gravity behave in the strong-field regime? Which is its phenomenology? Which is its nature?
Gravitational waves - that, after a decades-long, intensive experimental effort, should be finally detected in the next few years - will be the main probe on this still untested sector of nature.
