In Central physics auditorium of the Physics Department of Moscow State University on Wednesday, May 27, 2015, gathered a huge number of students and graduates of the University. They all came to hear one of the best-known theoretical physicists of our time - Kip Thorne (Kip Thorne), who came to Russia to give a lecture about his work on the film "Interstellar".

2014 Hollywood blockbuster with Matthew McConaughey starring captured the imagination of millions of people around the world and many of them asked the question "Is the space and the truth is?". That is the question theorist and Thorn decided to answer listeners his lecture "Interstellar - the physics behind the scenes."

"Interstellar", according to the scientist, conceived as a science fiction film, where all the details would be displayed with high accuracy from a scientific point of view. This picture should tell a wider audience about the mysteries of space over which the astronomers struggling for decades. Of course, without the art of speculation it has not done.

The idea to make this film came to Thorn back in 2006, when he by chance was on a blind date with Hollywood film producer Lynda Obst (Lynda Obst). Instead of a romantic relationship, this meeting turned into a strong business partnership: Obst and Thorne firmly decided to make a film that would tell the public about how mysterious and multifaceted space.

On the role of director Steven Spielberg originally invited, and although he liked the idea, and later he had to withdraw from the project. Then the scientist met with the brothers Christopher and Jonathan Nolan. Jonathan has written several dozen drafts of the script at work over which he constantly consulted a physicist Thorne. The plot, characters and other details is constantly changing, and even creators can no longer remember what was the original plan of a script.

According to Thorne, Christopher Nolan, he decided to work casually. "This director has an amazing flair for science", - explained the astrophysicist. Together, they worked through a variety of details that could affect both the development of the plot, and the visual component of the film.

The two main concepts upon which physics "Interstellar", this black hole and wormhole. Gargantua - a giant black hole in a distant galaxy, near which the heroes of the film are looking for habitable planets - is conceived sci-fi object.

First of all, Thorn has calculated various parameters of the object. He decided that the mass of Gargantua should be about 100 million solar masses, and its size should not exceed the size of the Earth: with such a huge density of celestial body can actually demonstrate the amazing "tricks" on the curvature of space-time.

According to the story, near Gargantua is some planet Miller, who could be the next home for mankind. "One hour on this planet earth is seven years", - he says in the film. It is a strange feature of the planet is due to its proximity to the black hole, and for the same reason she always turned her on one side.

The reason why the heroes understood that the planet Miller still unsuitable for life - a giant tsunami wave. Her height Thorn also counted manually: what will be the tidal force of the black hole Gargantua, if we know the density and mass of the space object? As a result, the scientist gave the team the artists draw the wave height which was about a kilometer.
The appearance of the black hole, which the heroes of the movie watching from the windows of their spacecraft, was also laid out in detail ("Vesti.Nauka" wrote about this in detail). The frame can be seen a giant ball of dark, surrounded, like a ring of Saturn, a luminous disc, which is also visible from above and below.
"Illuminated ring - this is the accretion disk of a black hole, that is all that many objects, which she sucks a huge rate. The glow of the top and bottom of a black hole - a Curved light coming out of it. In this case, Gargantua acts as a gravitational lens and distorts light waves coming toward the viewer, "- says Thorne.
Projecting an image of a black hole for "Interstellar", had neglected one important scientific part, admitted the scientist. The fact that the accretion disk, which consists of matter moving at speeds close to light, an observer would demonstrate the Doppler shift: approaching it objects would appear bluish, and moving away - dark-red.

Christopher Nolan idea to show a black hole with the Doppler effect appeared unsuccessful. "Our film will look a hundred million people, and 90% of the audience will not understand this way," - said the director of the picture. It was decided to leave the white light.
However, Nolan asked artists and scientists to modify the image of a little black hole: it should not look as if it saw people directly, as well, no matter what she looked through the camera lens IMAX. Artists draw the scattering of light from the accretion disk of a black hole, and the picture turned out a little blurred - it is such a camera would see it.

Working on the "design" wormholes, Thorne traced three possible image of this hypothetical object. He changed the length and width of the channel, as well as thought over how to keep the wormhole open (with the help of negative energy). The director chose one of the images - from as short channel, but he did not like computer simulation observer passing through a wormhole, it was too prosaic.

Therefore, the artists decided to combine the properties of the "short" and "long-barreled" wormhole so that the characters on the shivering spaceship could pass through it for several minutes, holding my breath. And so it happened.
As for the ending of the film, despite the mass of the proposed ideas, Christopher Nolan chose to leave it open.

"He really like the concept of Stanley Kubrick from the cult film" 2001: A Space Odyssey "- an open ending. Therefore, Nolan decided to give the audience decide what is it that happened at the end of the film with the characters and that they will continue", - he says Thorn.

However, as noted by the scientist, the main concept of physics "Interstellar" can be regarded as a kind of fifth dimension, which opens the main character when he dives into the black hole. Of course, this concept - purely fantastic, and while scientists believe that if an astronaut is really dare to repeat the act Cooper, it will stretch into atoms, like long spaghetti.

Kip Thorne, working on the film, wrote the book "The Science Behind the scenes Interstellar" (Science of Interstellar), which is recommended reading for anyone interested to delve into the theoretical ideas of modern astrophysics, bordering on fantasy.
