Physicist Karl Schwarzschild accidentally discovered black holes in 1916, when he was figuring out a particular solution to Einstein's general theory of relativity. He was trying to find the solution to the gravitational pull of a single, solitary, symmetric ball of matter — such as the sun at...
But the theory of black holes is accepted by many scientists and astronomers. 相关知识点: 试题来源: 解析 何谓黑洞?这个问题很难回答,因为我们没有恰当的词汇来来描述它们。科学家认为,黑洞是一个空旷的地带,物质往里面掉下去,而任何东西都不能从中逃出。因此,我们看不见黑洞。黑洞释放出强大的引力却又...
Abstract We argue that bound states of branes have a size that is of the same order as the horizon radius of the corresponding black hole. Thus the interior of a black hole is not ‘empty space with...
A. Black holes are extremely common. B. There are more than 100 billion galaxies in the universe. C. The black hole in our galaxy is pulling a gas cloud toward itself. D. Our universe is the product of a black hole in another, older universe. ...
White holes are black ones in reverse, spewing out matter– and they could give us our first glimpse of the quantum source of space-time, says physicist Carlo Rovelli
