Do gravitational waves exist?
It seems that gravitational waves do not exist. All efforts to observe them have been unsuccessful:
- Gravitational waves discovery now officially dead
- Although there's strong indirect evidence of gravitational waves, no one has yet detected one directly
From the theoretical viewpoint, gravitational waves are ill defined because gravitational equations are non-linear. An energy-momentum tensor of a gravitational field also is under discussion since it reduces to the boundary terms.
