The problem of the event horizon in relativistic gravity is discussed. Singular solutions general relativity are well known. Schwarschild metric a spherical mass singular at zero ($r = 0$) and r_g$). Both features reflect existence phenomenon collapse for compact masses exceeding $3M_{\odot }$. A material particle crossing falls into central singularity according to classical theory relativity. In quantum gravity, there may be no singularity. physics currently being refined. promising technique study gravitational waves (GW) accompanying merger binary black holes ringdown stage. GW observations quasi-normal modes newly formed super dense remnant will help clarify horizon.
