Scientists have discovered a “monster black hole” so massive that, in theory, it shouldn’t exist. It’s a stellar (恒星) black hole — the type that forms after stars die, collapse, and explode. Researchers had previously believed that the size limit was no more than 20 times the mas...

由第一段开头"Scientists have discovered…it shouldn't exist."可知,科学家们已经发现了一个"巨型黑洞"。再结合第三段开头"This theory has now…a press release from the Chinese Academy of Sciences."可知,但这个理论现在已经被新中国科学家发现的黑洞LB-1所推翻。所以判断出作者写这篇文章的目的是与读者...

Scientists have found the (close) black hole to Earth discovered so far. Named Gaia BH1, it is three times closer to our planet the previous closest known black hole. Gaia BH1 (weigh) about 10 times the mass of the Sun and is about 1600 light-years (the distance light travels in one...
This is when a supernova—the last stage of an exploding star—ejects(喷射) material during the explosion, which then falls back into the supernova, creating a black hole. This fallback formation is theoretically possible, but scientists have never been able to prove or observe it. There ...
