Wissenschaftler Enthüllen, Was In 30 Sekunden Im Weltraum Ohne Anzug Mit Einem Passiert

Did you know that they fool us all the time? These recordings are far from reality. In reality, space is not dark or cold and a person does not die there in a matter of seconds. It sounds fascinating. It isn't true. So what truth about space has been hidden from us? For years space has not really been black and all those scenes with astronauts falling into the great black abyss should be much more colorful. The point is that the universe is constantly expanding. The further away a galaxy is, the longer the light waves are. The waves emanating from it end up being so strong that they enter the infrared range that is invisible to humans, but that doesn't mean space is truly dark.

Even regular cameras with long exposures can capture more waves in the. night sky than we mere mortals can see, not to mention some special devices in different areas, however, a person would have the opportunity to see the entire game of bright colors if the universe suddenly became heavy, which is known as the all-boy. Paradox. In our infinite universe, there are stars everywhere you go. It is possible that if the universe stopped expanding, the entire sky would be as bright as the surface of our sun, regardless of whether it is day or night. As the light spreads, instead of numerous stars we only see black curls.

But the album paradox isn't the only phenomenon filmmakers often get caught up in. Otherwise, they would have already figured out why spaceships don't freeze. In fact, it is quite difficult to freeze completely in space, since it is not very cold. Instead of scenes where spaceships would be immediately covered in ice, it would be better to show them melting, such as the James Webb Space Telescope. It is located at a distance of 300 million kilometers from the sun. The radiation is so high that it must be constantly cooled and to do so it has five important sunshades and an active refrigerator that guarantees the normal operation of the extremely sensitive unit.

The electronics are guaranteed, but the ISS and the Hubble telescope are not so lucky, since they fly in the Earth's thermos at a distance of up to 700 kilometers from our planet. This layer is something special because the substance can reach up to 2,000 degrees Celsius. In the meantime, I would like to remind you that steel melts at temperatures between 1350 degrees and 1535 degrees Celsius. Why haven't the devices blown yet? Scientists have come up with some tricks to avoid this. surface, simply unnecessary, reflects radiation, then there is the protection against excessive heat in the ISS, which is basically a multilayer insulation made of practical polyethylene terephthalate and, despite its thickness of only seven thousandths of a millimeter, this material can withstand temperature fluctuations. 200 degrees and inside the device itself the screen changes only 0.5 degrees, which is quite impressive or the principle is the same as for spacesuits, it's hard to believe, but more and more often astronauts have to protect themselves not from the cold but from the unbearable.

Space suits store human heat and distribute it throughout the body, but what happens if we already know that space is not as cold as we have been told for years? Of course, there are still some cold spots in space, but it is surprisingly the coldest part of our planet. The system is on the Moon According to a scientist, the temperature inside the dark craters of the Moon was measured in 2009 at -240 degrees Celsius. This environment, which is so far from the known icy planets, is the directors' home, but what if they go beyond our solar system?

Everything is complicated here too. You know, when the volume of matter is abruptly reduced, the matter becomes hot and vice versa, when the volume expands rapidly, the temperature of all gases and class-rich objects in the universe. It is the red giants that form the protoplanetary nebula most quickly from their outer layers. This means that the coldest parts of space should be looked for there and not in the intergalactic space of the four masters, which currently appears to be the Boomerang Nebula. It is considered the coldest place, where the temperature is even lower than that of the cosmic microwave background and always remains at -273 degrees Celsius, but instead of pieces of ice and frost there is only an abandoned void.

That's why I think the space walk. The scenes in the film are mostly portrayed very inaccurately. Yes, but why doesn't a person without a spacesuit freeze in space? Even in boomerang fog, a body becomes completely cold after about a while, but after 26 hours. Why is this mainly due to density? Here it has already been observed that a person can stay in a sauna at 90 degrees Celsius for quite a long time. But it's not so easy to stick your finger in a 90-degree hot basin. It's all because in a poet's environment there are many more particles that come into contact with an object.

In space, the density of matter is extremely low with only ten atoms per cubic meter in some places, in comparison, on Earth each cubic meter of air contains. about ten trillion molecules, that's why even in the coldest parts of the universe you won't get too hot, but rather like a lamp slowly releasing its heat into the room, but besides other scary consequences, I guess everyone remembers the famous Total scene. Let's remember that the main character's eyes pop out of their sockets. In fact, the sudden vacuum causes the air in the lungs to expand, which can be fatal if the air is not exhaled quickly.

Therefore, in space it is advisable to simply stop breathing and. Additionally, compression can lead to egoism, a condition in which ambient pressure lowers the boiling point of body fluids and they begin to evaporate, which can lead to vascular occlusion, but even in this case the person will not. Interestingly, one of the most realistic spacewalk scenes comes from Stanley Kubrick's Space Odyssey, filmed in 1968, long before computer special effects and everything that comes with them. It seems that a director's hunch is sometimes more truthful, shown as scientific discoveries, yes, and what do you think other perceptions of space could turn out to be just our imagination?
