10 of the most common misconceptions about the cosmos born cinema

10 of the most common misconceptions about the cosmos born cinema

imagine that space - a space in which there is simply no gravity, the average man is quite difficult. Perhaps this is why, and strengthened at the level of representation of the space concept of the facts of the favorite intergalactic adventure films. We've gathered 10 of the facts that will dispel the stereotypes imposed by Hollywood of the cosmos.

Myth 1. In space, you hear the sounds of

10 of the most common misconceptions about the cosmos born cinema

On Earth, the atmosphere due to any objects connected to each other with respect to the dense medium. Evolution has created a way of collecting and interpreting the vibration of air or liquid around that allows you to get useful information about the world. In space, no air, no fluid through which to pass the vibration waves. And this means that the sound can not be. Engine sound and explosions - it's just a fiction filmmakers.

Myth 2. In space instantly freezes

10 of the most common misconceptions about the cosmos born cinema

Yes, in theory, space is very cold, but the heat exchange takes place only through the physical interaction of particles. In the absence of round particles can "absorb" the body temperature, it is cooled in the open space is very slow. Man suffocate faster in space than freeze to death.

The Myth 3. In space, you can accelerate infinitely

10 of the most common misconceptions about the cosmos born cinema

Some believe that without air resistance, or gravity, gradually accelerating objects can achieve almost infinite speed. In fact the problem is similar in dispersal is no fuel source, which may be infinite.

Myth 4: In space, there are fires and explosions

10 of the most common misconceptions about the cosmos born cinema

Fire - a combustion reaction gases in the air. No air and no burning. The maximum that can be seen in space - flash, which will "eat" the air from the space shuttle.

Myth 5. Soviet cosmonauts in orbit wrote in pencil

10 of the most common misconceptions about the cosmos born cinema

In the US, people tell that while NASA spent millions of dollars and years for the invention handles that can write in zero gravity, Soviet cosmonauts used graphite pencils. But it is worth remembering that in the world tiny graphite shavings left by the pencil, are deposited on the paper, or fall to the ground and in orbit they would have soared in weightlessness and sucked in air recirculation system. As a result, the astronauts to breathe graphite, and this is unacceptable.

Myth 6. On the surface of Mars can explode from internal pressure or choke

10 of the most common misconceptions about the cosmos born cinema

Since Mars has a very rarefied atmosphere, people there will certainly suffocate. But it is impossible to blow up because of man's inner pressure for this is simply not enough. even cases of depressurization suits were fixed in space, and nothing happened.

Myth 7 astronauts fly around on jetpacks ships

10 of the most common misconceptions about the cosmos born cinema

Despite the fact that with the help of compressed air can really maneuver packs are generally not used as it is portrayed in the films. In practice, packs are intended for use only in the event that an astronaut accidentally sail the ship to an unsafe distance. In addition, without using special large backpacks with compressed air far to the knapsack can not fly.

Myth 8. After the asteroid belt is very difficult to fly

10 of the most common misconceptions about the cosmos born cinema

Films have created a very common misconception about the asteroid belt. Yes, they are very high density, but only on the space standards: half a kilometer chunks fly at a distance of hundreds of thousands of kilometers from each other.

Myth 9. There is a "Dark Side of the Moon"

10 of the most common misconceptions about the cosmos born cinema

The fact that humans never see the back side of the moon, does not mean that it never gets sunlight. As the Earth orbits the Sun and the Moon the Earth, Moon, and each part is illuminated by the sun. Just the moon always faces the earth on one side.

10. Myth are in complete weightlessness in space, astronauts

10 of the most common misconceptions about the cosmos born cinema

It is often said about the possible health effects of living in a "zero gravity", but the reality is that no one ever really was not in weightlessness. One has only to remember that no one has ever been on the moon, and the moon enters the Earth's gravitational field. That gravity allows the astronauts to "float".
