Kip Thorne在《The Science of Interstellar》的纪录片里说,这次对虫洞和黑洞的可视化,够他写2篇论文了。然后我就一直在找他写的那2篇论文。
在纪录片里,有一篇叫做《Warmhole Lensing Length and Diameter》的论文的打印稿一闪而过,是他本人作为唯一作者写于2014年5月19日的。很可惜,这篇论文我在网上未能找到。哪位好人找到麻烦告知一下……
不过最近发现了貌似就是Kip Thorne所指的这2篇论文,大家可以下载来看。
黑洞可视化的论文是他于2015年2月16日上传到arXiv.org的《Gravitational Lensing by Spinning Black Holes in Astrophysics, and in the Movie Interstellar》。论文的链接是:http://arxiv.org/abs/1502.03808
第三块算是点科学发现。之前的其他论文都考虑在很远的地方,黑洞“看”起来啥样,这是为了在地球上通过各种发射到太空里的望远镜“看见”黑洞,然后拿来研究。(这里的看不是直接看黑洞,毕竟黑洞是黑的嘛,这里更多的是像看镜子里的看,因为黑洞就像一个引力透镜。)《The Science of Interstellar》纪录片里的“黑洞猎手”就需要那种(很远的)论文。但这次《Interstellar》是拍电影啊,当然要近距离看,于是推演着推演着方程,就有一些新的发现。
Nolan asked the visual effects team to convey a sense of travel through an exotic environment, one that was thematically linked to the exterior appearance of the wormhole but also incorporated elements of passing landscapes and the sense of a rapidly approaching destination. The visual effects artists at Double Negative combined existing DNGR visualisations of the wormhole’s interior with layers of interpretive effects animation derived from aerial photography of dramatic landscapes, adding lens-based photographic effects to tie everything in with the rest of the sequence. The end result was a sequence of shots that told a story comprehensible by a general audience while resembling the wormhole’s interior, as simulated with DNGR.
