The black hole that Interstellar created and didn't show us

Who went to the cinema to see the movie Interstellar can't even imagine that the black hole, in the movie called Gargantua, is the representation "closer to the real” has already been made on the subject, even taking into account the changes made in order to please the public.
To help with all the scientific part of the film, the producers were able to count on the support of the scientist Kipp Thorne. During the research and production of the space scenes, a new model was developed to create the images of a black hole, using real foundations of Einstein's theory of relativity and everything else that is entitled. After finalizing the model, the producers found the image too polluted, so some modifications were made to make the image more pleasant.

In the image to the side we can see each of the levels that the black hole had during the production of the film. In the first frame we see the simulation used in the film and we all saw it. Thorne and the producers describe this as a "moderately realistic" version.

The other two images show what a black hole really should look like. The main changes were the use of beams of light rays instead of individual rays and also the decrease in the rotation of the ring that surrounds the black hole.

The first modification makes the image smoother and more pleasing to the eye. In the original version, the image had a slightly unstable brightness and the light variation caused significant discomfort.

The second modification was even more aesthetic, because with the high rotation of the ring, the particles were very dispersed, making the image confusing to the spectators. After the treatment everything became more symmetrical and easier to understand.

Even not having used the complete images in the film, the work carried out by the team with the studio Double Negative was so accurate that the scientist decided to turn it into a scientific article that was sent for publication in November 2014 and published in January 2015.

Interstellar is one of the films most faithful to the scientific aspects we've had in recent years, earning great reviews from experts such as Neil De Grasse Tyson who, in an interview on the FOX channel, declared that he 8 e 9 (on a scale of 0 to 10) for the scene in relation to its “scientific fidelity or accuracy”.

We hope that many scientific films will come in the coming years and that they can contribute to the evolution of technology and space exploration.
