Gary Stephenson describes High Frequency Gravitational Waves (HFGW), which are changes or ripples in the fabric of space-time. Experiments such as LIGO explore lower-bandwidth counterparts to High-Frequency Gravitational Waves, and their existence is consistent with Einstein’s predictions. At the higher end of the spectrum, High-Frequency Gravitational Waves may either be produced by laboratory equipment as Stephenson proposes, or may naturally occur as processes inside of distant stars.
