Do black holes exist?

This project aims to verify if black holes can actually exist in our Universe. It is still unknown if any of the candidate objects possess the key black hole feature - a trapped region from which no signal can escape. By focusing on conditions for existence of trapped regions, this project expects to describe their neighborhoods and observable properties. This information is critical for interpretation of the data from the next generation of gravitational wave detectors and radio telescopes, and for determining the true nature of astrophysical black hole candidates. Further
benefits include simplification of calculations of the observable properties of compact objects and resolution of a long-standing black hole information loss paradox.
