The problem of bending and scattering of light rays passing outside from the entrance to a wormhole with zero gravitational mass is considered. The process of ray capture by a wormhole as well as the process of formation of a shadow when illuminated by a standard screen is investigated. These mechanisms are also compared to the case of motion of light rays in the vicinity of the Schwarzschild black hole.

  1. The glow of eternal black holes

    gr-qc 2026-08 accept novelty 6.0 of 10

    An eternal Schwarzschild black hole with an emitting surface at r=r_m would show a bright spot inside its shadow, whose interferometric visibility decays exponentially with baseline length.

  2. Observing of background electromagnetic radiation of the real sky through the throat of a wormhole

    gr-qc 2024-12 conditional novelty 5.0 of 10

    A simulation shows that a nearby wormhole mouth would project a lensed image of the real CMB sky and Milky Way inside its silhouette, offering a possible observational signature distinct from a black hole.
