Black holes stand at the limit of what we can know. To explore that edge of knowledge, the Event Horizon Telescope links observatories across the world to simulate an earth-sized instrument. With this tool the team pursues the first-ever picture of a black hole, resulting in an image seen by billions of people in April 2019. Meanwhile, Hawking and his team attack the black hole paradox at the heart of theoretical physics-Do predictive laws still function, even in these massive distortions of space and time? Weaving them together is a third strand, philosophical and exploratory using expressive animation. "Edge" is about practicing science at the highest level, a film where observation, theory, and philosophy combine to grasp these most mysterious objects

不是关于黑洞知识的科普，没有太多观看的价值。主要是讲有个小组是怎么把第一张黑洞照片拍摄出来的，其中拍摄的科学原理我没看懂。我是多倍速看的。
纪录片里面也介绍了一下霍金，霍金的《时间简史》、《果壳中的世界》、《大设计》我都是看了的，但是没有怎么看懂。
黑洞，通过辐射把自身吸收的能量再散发出去，直至消失。
