Thanks to high-tech telescopes, scientists have been able to discover black holes, monitor their jets of electrons, and now observe their illumination of galaxies. As black holes have now been discovered in almost every galaxy, scientists will next be able to connect these mysterious phenomena to the creation of galaxies themselves.
Despite the recent increase in observations of black holes spotlighting galaxies through their emission of radiation, fears that their growth could one day engulf the Earth are overblown. These celestial phenomena are amazing to observe and read about, but they're certainly not the outer space vacuum cleaners some claim they are.
There is a 70% chance that gravitational waves from the merger of supermassive black holes will be detected by November 30, 2027, according to the Metaculus prediction community.
