The main challenge astronomers face when trying to directly detect black holes is that black holes trap all light. This means that light cannot escape from them, making them invisible to direct observation. Instead, astronomers often infer their presence through the effects of their gravitational influence on nearby objects or the radiation emitted by material falling into them.
