Kip Suggested the use of actual equations that were used by VFX artists to render what scientifically a black hole would look like and it's amazing that he was right It looks so close to what they depicted in the movie.
Who would've thought that it would be possible to capture images of an existing black hole though? Soon enough we'll have images with even more detail. Science is awesome.
Now, will we ever be able to see an actual wormhole?
For Interstellar, Christopher Nolan created a real black hole just for the film because he did not want to CGI the galaxy in. After filming, he turned it around and started humanity so that they would come see his film.
