SUMMARY
Two supermassive black holes (SMBHs) are on a collision course, predicted to merge in approximately 10,000 years. This conclusion is based on findings from the paper titled "The Unanticipated Phenomenology of the Blazar PKS 2131–021," which indicates that these SMBHs are in a tight orbit with an orbital separation of approximately 0.001–0.01 parsecs. The study highlights unique periodic radio flux density variations over a 45.1-year light curve, suggesting a binary system with a rapid orbital period of just two Earth years. Current gravitational wave detectors like LIGO cannot detect these mergers due to frequency limitations, but optical telescopes are expected to monitor the event closely.
