Astronomy in films 

Interstellar (2014)

Interstellar is a science fiction film by Christopher Nolan, including the outer space and science.

Although the film looked like the information they are giving is true but they got the science wrong in some parts of the film.

1. One of the things they got right was partly the worm whole opening in space making the shortcut to another part of the universe. Worm holes are acceptable nowadays, in the modern cosmology and if we think of space-time as a form of fabric, then it can fold over on itself making that shortcut. According to Princeton cosmologist J. Richard Gott, for that to happen, there is a requirement which is negative energy. The negative energy is less than zero and it can make a portal and keep it open. There have been different attempts to make this condition happen in the lab which is way too far from what it actually is, but it at least proves the theory. According to Gott, a massive object is needed in order to make a required gravity field for the space-time to bent and that would be equivalent to 100 of the sun of our solar system; therefore, that would have a direct significant effect on its surroundings which did not got mentioned in the film. 

2. The other thing they got right was the time getting slower for people who get close to that amount of gravity of a massive object such as a black hole compared to people on earth. The explanation of this is simple, taking space-time as a fabric, when a massive object with high amount of gravity gets placed in it stretches time and space at the same time.

 3. Communication from a black hole to earth is still a possibility not more. A black hole is called this way because not even light can escape from it as its gravitational grip is super powerful. But science and physics still have place for development and more discoveries. According to the Hawking radiation discovered by Steven Hawking when the particles pop up near the event horizon of a black hole, negative ones can go in the hole and the positive one stays as a form of radiation. This form of energy which is left can carry information although another form of information is needed for that kind of communication, but this is still a good prove that it might be possible. 

4. The possibility of surviving the black hole with no consequences It is absolutely impossible to pass through a bla
ck hole without being affected in some way. You have to be faster than the speed of light in order to survive the spaghettification process. The time of the spaghettification depends on how close an object is to the centre of the black hole or its singularity. The closer the object is to the singularity the faster it faces that process; therefore, it takes more time to be stretched out in a bigger black hole. This part wasn’t fully covered in the film or script.

So in general they achieved to mention many information with good visuals in the film despite the fact that the script could get more scientific help.
