**SEZIONE DI FIRENZE** The recent observations of gravitational waves from binary black hole mergers
and of the ā€˜shadowā€™ of the supermassive black hole in the galaxy M87 have
finally delivered experimental data of phenomena where the limits of General
Relativity could be tested. One one hand, observations seem to confirm that
black hole candidates are well described by the classical relativistic
solutions. On the other hand, the existence of curvature singularities in such
solutions suggests that there must exist a regime where the classical
description fails.
Many theoretical models describing relativistic collapse without the occurrence
of singularities have been developed over the last few decades. Such models may
bear significant consequences for astrophysical black holes. The times seem now
mature enough to ask whether such consequences may be tested experimentally. (Daniele Malafarina - Nazarbayev Univ. - Kazakhstan) |
