为了了解星系是如何形成的,我们需要追溯到宇宙刚刚诞生之初的时候。那时候,宇宙充斥着大爆炸残留的气体云,一些地方拥有浓稠的星际气体,从而形成了数千万颗恒星。最初的恒星中大多都是超大质量恒星,它们温度极高,燃烧速度也快,它们在爆炸之后产生了大量的黑洞。热心网友 时间:2022-06-20 23:58
In 1971, Hawking pointed out that "under the extreme high temperature and pressure of the big bang, black holes are likely to appear. After all, as long as the pressure is high enough, any object can collapse into a black hole. Unless the distribution of matter in the universe is very regular ring the big bang, there must be some areas that are too thin and some areas are too dense, and black holes will inevitably appear in areas with too much density. " I continued to think based on this hypothesis: in areas with too much density, black holes will devour the surrounding material as soon as they appear. It makes the volume and mass of black hole increase rapidly. At the same time, it drives the surrounding materials to rotate around the black hole, and the surrounding materials collide with each other and squeeze to form planets, stars and other planets, thus procing the most primitive galaxies.热心网友 时间:2022-06-20 23:58
每个类星体都是年轻星系的雏形,并且在它们中心都存在一个超大质量黑洞。因此可以说,超大质量黑洞和类星*造了星系,并控制着整个星系。热心网友 时间:2022-06-20 23:59
写得非常好,而且写的很多,对于初中的孩子来讲他们是听得懂的但是给四年级以下的孩子就听不懂以后希望能讲一个小学和初中都能听懂的
