宇宙史上最大“黑洞撞黑洞”，合并诞生超太阳265倍质量新黑洞

Core Insights - The LIGO observatory has detected a significant event involving the merger of supermassive black holes, designated GW231123, occurring 10 billion light-years away, resulting in a black hole with a mass 265 times that of the Sun [1] - This event sets a new record in gravitational wave observations, with the merger's gravitational wave signal lasting only 0.1 seconds but containing substantial information [1] - The two original black holes had masses of 103 and 137 times that of the Sun, and the newly formed black hole spins at a rate 400,000 times that of Earth's rotation, approaching the theoretical limits of general relativity [1] - This discovery may represent the first clear observation of "second-generation black holes," potentially transforming the understanding of black hole formation and evolution [1] - Notably, both original black holes fell within the "mass gap" of 60-130 solar masses, a theoretical region previously considered forbidden [1]
