英文原文:Explanation: What would it look like to plunge into a monster black hole? This image from a supercomputer visualization shows the entire sky as seen from a simulated camera plunging toward a 4-million-solar-mass black hole, similar to the one at the center of our galaxy . The camera lies about 16 million kilometers from the black hole’s event horizon and is moving inward at 62 percent the speed of light . Thanks to gravity’s funhouse effects , the starry band of the Milky Way appears both as a compact loop at the top of this view and as a secondary image stretching across the bottom. Move the cursor over the image for additional explanation. Visualizations like this allow astronomers to explore black holes in ways not otherwise possible. 说明: 想像一下,如果坠入一个巨型黑洞会是什么样子? 这张由超级电脑可视化[8]生成的图像展示了一台仿真相机[9]拍摄的整个天空景象,这台相机正朝着一个质量约为400万个太阳质量的黑洞俯冲而去,这个黑洞类似于我们银河系中心的黑洞[10]。 相机位于距离黑洞的事件视界[11]约1,600万公里处,并以62%的光速向内移动。 由于重力的欢乐屋效应(funhouse effects)[12],银河系的星带[13]在图像顶部呈现为一个紧凑的环状结构,而在底部则以拉伸的方式[14]呈现出来。 将光标移到图像上可以获得更多的解释。 像这样的可视化技术[15]使天文学家能够以其他方式无法实现的方式探索黑洞[16]。
