Where do black holes lead to? If a massive object crosses the event horizon, it will be sucked into the black hole and never escape. What happens inside the black hole is unknown; even our current theories of physics do not apply in the vicinity of a singularity. What are the two types...
But where do black holes come from? How do they form, and what gives them such awesome destructive power? [Stephen Hawking's Most Far-Out Ideas About Black Holes] Before we can answer that, we have to ask an even more fundamental question: Just what is a black hole? "Basically, it'...
Initially, black holes were considered nothing more than abstract mathematical concepts; even Einsten assumed they didn’t actually exist. But in 1931, the astronomer Chandrasekhar calculated that certain high mass stars might be able to collapse into black holes after all. They turned out to be r...

甚至可能有一颗恒星靠得太近了 Maybe even a star got a bit too close. 吸积盘不仅仅是气体和尘埃 Accretion disks are not just gas and dust. 黑洞会把所有东西都拖进去 Black holes will drag in anything and everything. 有恒星有气体 There are stars. Theres gas. 气体云中,有恒星正在形成 Theres ...
Such objects include brown dwarfs, exceedingly dim white dwarfs, neutron stars and even black holes. MACHOs probably contribute somewhat to the dark matter mystery, but there are simply not enough of them to account for all of the dark matter in a single galaxy or cluster of galaxies. ...
Gamma rays and cosmic rays are high-energy particles and radiation that originate from various sources in the universe, such as supernovae, black holes and even the Big Bang itself. Scientiststheorizethat antimatter should be as abundant as ordinary matter because of the Big Bang, but it's sc...
We treat theory and observations in the framework of the philosophical discussions about “(anti)realism and underdetermination”, as this line of arguments allows us to describe the situation in observational astrophysics with respect to supermassive black holes. Questions concerning the existence of ...
While we'd love to declare a clear winner in the brewing AI battle here, the results are too scattered to do that. DeepSeek's R1 model definitely distinguished itself by citing reliable sources to identify the billionth prime number and with some quality creative writing in the dad jokes an...
I am often asked, 'How do you find new reactions? Where do you get your ideas?" 翻译: 谢谢各位,我很荣幸受邀以霍尼韦尔诺贝尔奖演讲者的身份访问天津大学。 我非常高兴在此见到天津大学的所有杰出成员,也非常激动在此见到这么多热情的年轻科学家和工程师—在你们身上我看到了中国的未来!
