天文学家正在研究一个可能以超高速穿越星际空间的超大质量黑洞，其形成原因和性质仍存在争议。
Have astronomers found a runaway monster black hole or just a very weird galaxy? Despite years of debate and follow-up studies, an odd streak of cosmic light still defies a final explanation. Is it a giant black hole screaming through intergalactic space? There is something inherently terrifying about a supermassive black hole hurtling through space at an excess of three million kilometers per hour. Normally these behemoths squat at the centers of galaxies and for good reason; they’re usually the single most massive objects in their host galaxy and thus aren’t easily budged. But then there’s RBH-1. As a hint, the acronym “RBH” stands for “runaway supermassive black hole,” and this object may be just that: a monster some tens of millions of times the sun’s mass hauling astronomically through intergalactic space at mind-crushing speed.
