In Mysterious we talk to you once about 8 objects that were left on the Moon.The space and everything that has to do with it is fascinating.If you are also interested, keep reading.
Recently I went to see "Interstellar" at the cinema.I confess that, despite getting lost somewhere in history, pending to see her again, I liked the movie quite a bit.In spite of the possibility that some celluloid connoisseur can take my colors off, I dare to say that it is a good film , at least as regards his scientific argument .

But this is not always the case.In many occasions, and pro of an impressive acoustic and visual result , the cinema , in matters of science , and especially in space thematics, it has opened the door of doubt, giving rise to many beliefs that are essentially false . How much damage Hollywood has done! They would say some not without lack of reason, that's why in this article we want to demystify several beliefs, some promoted by the big screen industry, others not.
Curiously, having no atmosphere, its temperature does not increase as much as in the case of Venus .Where the higher temperatures exceed the figures of Mercury.Another factor that significantly affects this fact is the time it takes to rotate : 58 days.During the night in Mercury, is reached almost 180 degrees below zero .Bestial!
It is not really necessary to perceive the light of a star with your eyes to know what your color, but we can deduce it from the temperature.In the temperature range of the stars, those of a shade between brown and dark red are the “coldest”.As their temperature is higher, a reddish hue and the clearest is the one that is evidenced, following a gradation that goes from orange to white, through yellow, at the other end of the spectrum, the stars more hot are those that have a bluish tone.
Time ago, Venus was one of the strongest candidates to host extraterrestrial life.Once the planet was studied in depth, it was demonstrated that the thick Venusian atmosphere hid the deadly and inhospitable that could become the surface of the planet.
Space suits are pressurized , that is to say, they are like individual pressurized booths and, therefore, they should appear swollen, as if it were a suit made of balloons with a person inside, so the movement would be much more complicated than in most movies.
We cannot apply the same reasoning when we talk about the moon with respect to the sun.the Moon, as a companion of Earth's orbit around the Sun, receives sunlight on its entire surface at one time or another, a fact that from the Earth it is impossible to appreciate through me The observation.
Of course, one goes to the cinema and would not expect anything else to enjoy the The acoustic surround of the Dolby Surround, while the ship in question is reduced to peaks in just a few moments, but the truth is that if the films were faithful to reality, said explosion should occur in the most absolute silence .It is strange to get the idea, but it is exactly like that.Sound is propagated by waves and they need a means material for their propagation.In the case of the Earth, the material medium is provided by the atmosphere.In space, in the absence of a means by which to propagate , no sound would be produced.
Be that as it may, the cinema will still be cinema.So next time, enjoy the staging, and if you have the opportunity to tell someone what you have here learned, do not hesitate to make the "smart", just wait for the movie to end.

8 space myths that you should stop believing
1.Mercury is the planet with the highest temperature
While it is true that Mercury is the planet that is closer to the sun in our Solar System, no is the fact that this is why it reaches the highest temperature .Bad news for those series and movies that referred to Mercury as the hottest planet because of its proximity to the Sun.
Curiously, having no atmosphere, its temperature does not increase as much as in the case of Venus .Where the higher temperatures exceed the figures of Mercury.Another factor that significantly affects this fact is the time it takes to rotate : 58 days.During the night in Mercury, is reached almost 180 degrees below zero .Bestial!
2.Inside the Sun nothing burns
Although it is true that it is a huge incandescent sphere, inside nothing burns from the Sun .They are nuances that can go unnoticed by those who are not experts, but the Sun generates its heat based on the energy produced by the reactions of nuclear fusion that they occur inside, and not due to chemical combustion reactions.3.The sun is yellow
The sun is not yellow .skeptics would say that there is nothing more to go out to the street and look at the sun to realize what its color is.However, the yellow hue we perceive from solar radiation is due to the effect produced by the atmosphere when it is crossed by the beams of light.However, the sunlight is white.Do not hesitate to ask an astronaut if one day you meet any.
It is not really necessary to perceive the light of a star with your eyes to know what your color, but we can deduce it from the temperature.In the temperature range of the stars, those of a shade between brown and dark red are the “coldest”.As their temperature is higher, a reddish hue and the clearest is the one that is evidenced, following a gradation that goes from orange to white, through yellow, at the other end of the spectrum, the stars more hot are those that have a bluish tone.
4.Venus and the Earth are identical
Venus has been presented on many occasions as the twin planet of Earth, which should not give the impression that both are exactly identical.
Time ago, Venus was one of the strongest candidates to host extraterrestrial life.Once the planet was studied in depth, it was demonstrated that the thick Venusian atmosphere hid the deadly and inhospitable that could become the surface of the planet.
5.The baggy astronaut suits
Those wrinkles in the astronaut costumes of the movies already seem normal to us.The problem we want to point out is not exactly iron, but scientific.
Space suits are pressurized , that is to say, they are like individual pressurized booths and, therefore, they should appear swollen, as if it were a suit made of balloons with a person inside, so the movement would be much more complicated than in most movies.
6.The Chinese wall can be seen from Space
Even today, it is a very present myth and in which many people believe, and whose origin dates back to the 16th century.But the truth is that, even once man arrived in space, it took a long time to deny the claim .The moon landing was necessary in our tro satelite, and the statements of the astronaut Neil Armstrong , so that many would be convinced of the falsity of the fact.7.There is a dark side on the Moon
The idea that the Moon has a face constantly bathed in darkness is also not true.The position of the Moon with respect to the Earth is fixed, in the sense that our satellite is devoid of a rotational movement own .This makes the same face with respect to the observer, in this case the inhabitants of Earth,
We cannot apply the same reasoning when we talk about the moon with respect to the sun.the Moon, as a companion of Earth's orbit around the Sun, receives sunlight on its entire surface at one time or another, a fact that from the Earth it is impossible to appreciate through me The observation.
8.The sound in space
Returning to the cinema, in countless space-themed films, the magnanimous and colossal explosions are very recurrent, which end up spreading the remains in all directions, of what a spacecraft had been a few seconds before.As it cannot be otherwise, the detonation is inherently accompanied by the respective explosion, a lot of fire-maybe too much, since there is no oxygen in abundance to produce the combustion-, and a loud "BOOOM", "BAAANG", or "CATAPUUM"...already to the taste of the sound technician.
Of course, one goes to the cinema and would not expect anything else to enjoy the The acoustic surround of the Dolby Surround, while the ship in question is reduced to peaks in just a few moments, but the truth is that if the films were faithful to reality, said explosion should occur in the most absolute silence .It is strange to get the idea, but it is exactly like that.Sound is propagated by waves and they need a means material for their propagation.In the case of the Earth, the material medium is provided by the atmosphere.In space, in the absence of a means by which to propagate , no sound would be produced.
Be that as it may, the cinema will still be cinema.So next time, enjoy the staging, and if you have the opportunity to tell someone what you have here learned, do not hesitate to make the "smart", just wait for the movie to end.
