Space has long been part of popular science fiction. With space movies we venture into the unknown, and with modern CGI and MovieMaking technologies they are also a real spectacle.
Despite pop culture's love for space, there are still many things Hollywood is wrong. You'd think we have an idea of what it's like out there, but because of movies, many of us may imagine the room very, very wrong.
Well, we do not say that movies have to do everything right, because every fiction requires some lifting of disbelief to have fun. We're just saying that our idea of space would be a bit closer to reality if scriptwriters just looked at a few things online before writing their designs.
0 Explosions in Space
There's no doubt that seeing a huge space blast on a big HD screen is one of the ten best things in life. Apart from impressive pictures, it is quite another matter whether these explosions are scientifically possible or not. Explosions on Earth – from which the films are inspired – look like they do because of air and gravity. The air acts as an oxidant, and the pressure from the explosion causes the explosion to fly outward and fall back into the ground.
However, space explosions would be very different (and much more impressive). Despite the lack of air, there would be a fire, as some types of fuel can act as an oxidizer, although it is not like the fire we know. This fire would look like a continuously expanding ball of light due to microgravity and lack of air resistance. It would also be dangerous for nearby spaceships, as unlike terrestrial explosions, the splinter expands outward until something stops. 
9 Black Holes Suck It All
Black holes, like all in movies, are consumed-devouring swirls of destruction and destruction that you can not escape when you're around. That's what most of us imagine, because we really have nothing else to do – these physics books are too complicated to read.
However, if you yourself read the most basic academic description of black holes, you would find that we have massively misunderstood them. They are no different from other celestial bodies in the universe because their attraction is directly proportional to their mass. They can not wear anything more than their size allows. If our sun were replaced by a black hole as massive as itself, the solar system would not change at all – at least gravitationally, since the sun is somehow important in other areas.
That's Right For a black hole to devour everything near its event horizon, it only has a normal gravitational effect on things outside that radius (which is usually very small). 
8 The asteroid belt is dense and crowded
] The inner and outer planets of the solar system are separated by the so-called asteroid belt. As the name implies, it is a ring of asteroids and other debris turning around the sun, and movies have always taken it as an opportunity to use it. Normally, the belt is a crowded area, with dense stone clouds, through which one has to skillfully maneuver to get to the other side.
If you have imagined the asteroid belt like this, we are sorry to report that your mental image is massively inaccurate. The sky of an asteroid in the belt would be very similar to the sky from Earth due to the distances we are talking about. For every spacecraft it happens, the likelihood of a collision is very low because the asteroids are far apart. 
7 All about Space War
It goes without saying that we create a model of space warfare after battles on Earth, as this is the only frame of reference that we have. Space battles resemble aerial combat seen in World War II films, with spacecraft fighting like airplanes on Earth.
While these fights look fantastic, they are not based on scientific reality.  Real Space Warfare Probably does not look like a movie, with warships designed to prevent decompression and resist radiation rather than aerodynamics. Even the usual air combat tactics would not work in space. While the general battleground strategy of Earth-based warfare would still apply – the wrapping would probably still work the same – movement and maneuvering in a real space battle would be alien to anyone who grew up seeing Star Wars .
6 The sun is yellow because it is burning
Although this is the main reason for life on Earth, most of us still do not understand how the sun actually works. We assume that it has a yellow color, possibly because we think it burns, and that's the fire. This also means that we do not fully understand why the sun generates so much heat.
For one thing, the sun is not yellow at all, and it just looks as if the Earth's atmosphere colors it so yellow. Sunlight is a pure white color.  More importantly, the sun does not burn at all, at least not as we normally understand it. Instead of an eternal fire, the heat of the sun is created by fusion reactions of different molecules in their nucleus.
5 Planets always revolve around their stationary suns
When we think about the different solar systems around the universe, we imagine it just like ours. In the middle is a stationary star, and depending on whether the system has planets, various celestial bodies rotate in circles / ellipses around it, regardless of their size.
While this is pretty much true in our sunlight for our cosmic neighborhood system with more than one planet as big as Jupiter (or larger), their rotation would look very different and you would probably see the star in some sort of way as well See movement.
Gravity is a two-way force, so the earth pulls the sun and the sun pulls us. We just do not notice it, because the gravitational effect of the Earth is negligible compared to the Sun, although this is not the case with larger planets. In the case of Jupiter and the Sun, they are actually circling one point in space beyond the solar surface.  This effect would be even more pronounced in systems with many huge planets like Jupiter. So, in general, we do not envision all the solar systems in the universe.
4 Laser beams are visible
Laser weapons have been part of science fiction films for quite some time. Now that we're about to see them on the battlefield, most people would be disappointed to find out they have nothing to do with the movies.
A laser beam is essentially a concentrated burst of energy that could be used. For various battlefield functions, space opera directors have used too much at this point too often. However, unlike films, real-life laser beams in space would be completely invisible (unless they go directly into your eye), as there should be no particles in the vicinity to scatter the light. 
It is generally accepted that you are weightless in space. This seems to be a reasonable assumption, as there is no gravity. Many films and fictional works prove this, and there are many videos of people floating in space, suggesting that they are indeed weightless.
Many astronauts feel weightless in space, but only when they are in orbit around a larger body. This happens, for example, on the International Space Station (ISS). Otherwise, you are always under the influence of gravity, no matter how weak you are. They are never really weightless in space, unless you are in a constant fall around a planet or other celestial body, as is the case with the ISS. We're not sure why movies still treat the entire room as a gravity-free zone because gravity is everywhere in the room.
2 Sound In Space
The idea that you can hear the sounds of explosions in space is largely due to the space movies of the past century. It is not true; Due to lack of air and vibrating molecules, the sound can not move in space.  We should be grateful for that as well, for if possible we could always hear the sounds of the universe, like the constant thermonuclear explosion that is our sun.
Although we can now better imitate real physics, we use the trump of exploding things in space and making deafening noises, as they are rendered better on screen than just a noiseless picture. While films like Stanley Kubrick's 2001: A Space Odyssey have managed to achieve this goal, such films are the exception rather than the rule.
1 Nothing in the universe can go faster than the speed of light
The speed of light is considered the ultimate barrier to humanity, as it is usually considered impassable. There are all sorts of theories about what it will be like to reach this point, but none of our equations explains that we go beyond that.
We happen to know that at least one thing in the universe is faster than the speed of light: the speed of its expansion. To the confusion of scientists and occasional sky watchers, it has been discovered that the universe expands faster than the speed of light (at least with respect to the speed of various objects, such as distant galaxies, relative to each other), although this is not the case. We understand that very well. The rate of expansion is also proportional to the distance; the farther it is from us, the faster it moves away. 
That's not all; There is a scientific – albeit theoretical – proof of particles that could travel faster than the speed of light, although we have not yet been able to find them in reality. Many scientists believe that there are more things that could challenge the light barrier. We just have to find her.
