Every time a new telescope (radio, UV, IR, sensitive, etc) is constructed, new discoveries are found. Why should this be different for graviational waves?
This calculator shows that at nuclear (1e21 Hz) +/- frequencies, there is room for vast amounts of energy to be travelling in space 'right under our noses'.
Researchers - please ignore the conventional wisdom of theoretical physics and consider experiments to detect gravitational waves in the ultra high frequency regime.
