  In this essay we look at the possibility of vacuum production of very low
frequency electromagnetic radiation from a gravitational wave background (i.e.
gravity's light). We also propose that this counterpart electromagnetic
radiation should be detectable by a lunar orbiting satellite which is
periodically occulted by the Moon (i.e. in the shadow of the Moon). For
concreteness we consider the possibility of detection of both the gravitational
wave and hypothesized electromagnetic radiation counterpart from the supernova
core collapse of Betelgeuse.
