artifact description
We take for granted that Gravitational Waves (GWs) exist, but examine critically the possibility for their direct observation with ground and space-based laser interferometers. It is argued that the detection of GWs can, at least theoretically, be achieved iff three requirements are met en bloc. Alternatively, a hypothetical case related to the so-called dark energy would render the task impossible in principle. The discussion is kept at conceptual level, to make it accessible to the general audience.
