Abstract

We show that photon spheres of supermassive black holes generate high-frequency stochastic gravitational waves through photon-graviton conversion. Remarkably, the frequency is universally determined as m(e) root m(e)

m(p) similar or equal to 10(20) Hz in terms of the proton mass m(p) and the electron mass m(e). It turns out that the density parameter of the stochastic gravitational waves Omega(gw) could be 10(-12). Since the existence of the gravitational waves from photon spheres is robust, it is worth seeking methods of detecting high-frequency gravitational waves around 10(20) Hz.
