Scientists at Stanford University investigated the supermassive binary black hole in elliptical galaxy B2 0402+379. According to Phys.org, this pair of black holes turned out to be the record holders for the mass of all objects ever discovered in the universe. Astronomers estimate that the mass of the binary star system is 28 billion times the mass of the Sun. Please remember. Our star has a mass of 1.98892 × 1030 kilograms, which is approximately 332,946 times the mass of Earth. The calculations used data from the Gemini North telescope in Hawaii. The black hole is 24 light years away. Space-wise, it’s not that much. For a long time, scientists could not explain why black holes got “stuck” in the final stages of merging. They have remained in this state for at least 3 billion years. There is no exact answer, but one hypothesis is that the black hole ejected almost all the material around it, leaving the center of the galaxy empty of stars and gas. There is nothing left to further slow the companies’ trajectory, and their final stage merger has stalled. Astronomers need to know whether the pair will overcome stagnation and eventually merge within a few million years, or whether they will remain stuck in orbit forever. When the black holes in galaxy B2 0402 + 379 merge, the resulting gravitational waves will be 100 million times stronger than the gravitational waves produced by a normal black hole merger. How many planets are there in our solar system? Eight? Some may object. We found out what Pluto is and who considers it a planet on a legal level.
