Abstract

The problem of the passage of light through the mouth of a zero-mass wormhole and the possibility of observing the objects from another asymptotically flat space-time through the mouth of a wormhole are considered. It is shown that an individual star can have several images and the fact that the image of a flat Lambertian screen has a complex brightness distribution for an observer located on the opposite side of the throat. Images of two such screens visible inside the silhouette of a massless wormhole and the distribution of radiation intensity in their images are constructed.

Notes

  1. In numerous works on the bending and scattering of light rays by black holes and wormholes, the resulting dark formations are called either “shadows” [5, 6, 7], or “silhouettes” [8, 9]. We consider the term “silhouette” more appropriate and will continue to use it.
