Are Some of the Black Holes Detected, Wormholes Instead?

Many compact gravitational objects in the cosmos such as black holes, naked singularities, and wormholes, can only be detected by their shadows’ signatures. Distinguishing their different natures through their shadows is a difficult task because many times their shadows are very similar. Therefore, we can’t rely exclusively on this information to discern unambiguously the specific spacetime geometries from the objects.

For instance, the radio images obtained from the Event Horizon Telescope to directly observe the accretion disks of the supermassive black holes in the galactic centers, are hard to interpret since the information about their gravitational field is coupled non-linearly to the magneto-hydrodynamics of the system.

The main feature analyzed in such images, is their intensity profile. An interesting approach to constrain further the space time geometry, is to...
