Radio signals emitted by a star-sized black hole

The radio signals emitted by a star-sized black hole could result from various astrophysical phenomena, such as the emission of charged particles in its surroundings or interaction with an accretion disk of falling matter. Scientists might be puzzled because these signals could challenge current theories about how black holes function and interact with their surroundings. Additionally, the exact processes occurring near a black hole can be extremely complex and challenging to model accurately, adding to the uncertainty. Studying these signals could lead to advancements in our understanding of black hole physics and extreme phenomena in the universe
