The moment Hollywood fooled us with space movies

  • There are countless things about space that we still don't fully understand.
    That's why researchers are always investigating, confirming hypotheses and publishing findings in scientific articles.
    However, you must agree that the image that most people have of the universe does not come from academic articles, but rather from Hollywood films aimed at the general public, where spectacle is the priority.
    And, to create this engaging spectacle, film directors sometimes end up deceiving us.
    In this way, they subtly insert impressive scenes that replace scientific facts.
    Inertia
    Do you remember what Newton, the famous physicist and mathematician, said?
    "Every body continues in its state of rest, or of uniform motion in a straight line, unless compelled to change that state by forces applied to it."
    This statement is known as Newton's First Law.
    In science fiction films, it is quite common to see the protagonist turn off the engines of a spaceship, and it immediately stops.
    Now think about what would happen if the engines of a plane flying over the surface of the Earth were turned off. According to the law of inertia, it would continue flying indefinitely. However, taking into account air resistance and the gravitational pull of the Earth, its speed would decrease and its altitude would change. Asteroids One of the most memorable and exciting scenes in "Star Wars" is when Han Solo makes a risky maneuver to escape from Imperial fighters, entering an asteroid belt. During this sequence, giant rocks come flying from all directions, colliding with each other and putting the ship "Millennium Falcon" in constant danger. The only thing that helps Han Solo escape this extremely dangerous situation is his exceptional skill as a pilot and a bit of luck. Of course, we cannot be sure about what happens in "once upon a time in a galaxy far, far away", but here in our Solar System, it would be very unlikely to film such a dramatic scene. In fact, there is an impressive amount of rocks between Mars and Jupiter, known as the main belt.
    It is estimated that there are billions of these rocks.
    The yellow Sun
    We are all very used to thinking of the Sun as a yellow star.
    In children's pictures, the Sun is often yellow or red, but close to the horizon, the Sun can appear orange or red, depending on the atmospheric conditions, the time of day and the season.
    This color change occurs because the atmosphere scatters blue and violet light.
    However, only film directors keep the image of the Sun in its classic yellow tone.
    The truth is that the Sun shines with a white light.
    This fact can be seen in images from the International Space Station.
    Sound
    The slogan of the film "Alien", directed by Ridley Scott, was the following.
    "In space, no one can hear you scream."
    Yes, that is true.
    For most people living on Earth, sound is something natural that we are used to perceiving everywhere.
    However, in space, where vacuum prevails, everything is different.
    There is no medium capable of transmitting elastic waves, like air here on Earth.
    Asteroids
    The Earth is just a sphere floating in space, and we do not know when it will be hit by a major disaster.
    Just as a giant asteroid in the past abruptly ended the prosperity of the dinosaurs, another large rocky body could do the same to humanity.
    For example, if an asteroid about 300 meters in diameter collided with Earth, it would release an energy several times greater than the sum of all the nuclear weapons currently in existence.
    This type of catastrophe must be avoided at all costs, right?
    Thanks to NASA's Near-Earth Object Observation Program, known as NEO (Near-Earth Object), we have the ability to detect potential unwanted visitors from space in advance, and in this case, the only solution would be to destroy the asteroid.
    At least in the movie "Armageddon", the hero played by Bruce Willis and his team drill the asteroid to place a nuclear bomb inside it.
    The cold
    In the movie "Mission to Mars", directed by Brian De Palma, the director opts for a dramatic scene to capture the audience's attention.
    In one of the scenes, astronaut Woody Blake, played by Tim Robbins, floats adrift in space and, to save his wife, Terri Fisher, he decides to remove the helmet of his spacesuit.
    It is a curious scene, but what comes next is even more intriguing.
    When Woody removes his protective suit, his body freezes instantly, turning into a block of ice thrown into the void of space.
    The problem is that this impressive scene would not be possible in reality, considering the properties of the vacuum.
    In space, where there is almost nothing, the conditions are completely different from those we know on Earth.

    A medida que o espaço vai ficando vazio, a temperatura cai. No vácuo total (ausência de matéria), a temperatura despenca para até 272 ºC negativos, 1 grau acima do zero absoluto. “É como medir a temperatura mínima do espaço. Não há local mais frio que esse.

    Impressionante mesmo! Quer dizer que precisaríamos de um corpo rochoso com pelo menos 300 metros de diâmetro para criar uma arma com um poder de destruição superior a energia liberada por todas as armas nucleares da Terra??? Então o que poderíamos esperar se um corpo do tamanho de Ceres ou 951 Gaspra nos atingisse??? É por isso que alguns governos mostraram interesse em controlar a órbita de alguns deles. Poderiam usá-los como artefatos bélicos.
    Vídeo TOP !!!!

    Tudo explicado corretamente no vídeo.
    Porém, tem uma pequena ressalva sobre os asteroids estarem "pertos", porque tem que levar em consideração a perspectiva da velocidade e tempo.
    Nos filmes essas naves percorrem a uma velocidade próxima a da luz, o que faz uma distância enorme parecer pequena.
    Mas... sim, eles dão uma exagerada 😅

      E quanto as mortes nos filmes, seria pior na vida real.
      Realmente o espaço é frio, mas como explicado no vídeo, não seria um congelamento instantâneo, e nem daria tempo de morrer por falta de ar como alguns filmes mostram, na verdade morreria antes, como ele citou no vídeo, provavelmente, seus órgãos explodiriam.

    Acredito que explosões no vácuo espacial seriam possíveis apenas enquanto o oxigênio disponível para uso humano estiver queimando. Ao acabar o oxigênio acabaria o fogo.

    Eita, Star Wars foi escrito no final dos anos 60 e início dos Anos 70, naquele tempo, ninguém tinha pretensão de fazer um filme científico, Star Wars é o conto de fadas do espaço, Ninguém questiona Bela adormecida, diferentemente de Interestelar, Armargedon que foi feito pesquisas para chegar um pouco próximo a realidade.

      Não confundam a luz do Sol, que é a junção de todas as cores do espectro, e portanto branca, com a classificação do Sol (anã amarela) e a incidência da luz na atmosfera (amarela). São três coisas diferentes.
