黑洞理论的确能解释许多现象,观察到的黑洞候选也很多?了,反正就科普级别而言 ... 黑洞理论的确能解释许多现象,观察到的黑洞候选也很多?了,反正就科普级别而言我是信了。
我只是纯吐槽你的
”黑洞因为被多次间接观测到了,黑洞辐射只有一次没证实没再现的观测,所以你信前者不信后者“
这态度。太正义了。
我说过黑洞辐射被观测到了?
前文我提到的是实验室里发现了霍金辐射现象[http://arxiv.org/abs/1009.4634],不是说在黑洞附近发现了辐射现象;
而且有很多反对意见,比如这里的一个报道[http://www.scientificamerican.com/article.cfm?id=hawking-radiation],
如果你懒得仔细看,稍微注意下这几句话就可以:
The relatively faint emission has never been detected from a real black hole, so researchers have sought a number of laboratory proxies to demonstrate the general principles of the phenomenon. One possible issue is that the Faccio group's photons emerge from the glass at a 90-degree angle from the direction of the laser pulse. "That is the wrong direction, and it is really hard to see how that could happen," Unruh says. |
