What are the dangers of human beings in space without spacesuit protection?

We know that if humans want to go into space, they need to wear special spacesuits to protect themselves, because the environment in space is undoubtedly fatal to humans. If humans are directly exposed to the space environment, they will die quickly due to factors such as low temperature and cosmic radiation.

The environment in space is far worse than we think, as we all know, there are countless celestial bodies in the universe, these celestial bodies are emitting electromagnetic waves, and some of them emit high-energy particle rays, scientists call these electromagnetic waves, particle rays and other radiation collectively called cosmic rays. You must know that the reason why human beings can survive on the earth is largely due to the existence of the atmosphere, which helps us block most of the cosmic rays.

In addition to the excessive amount of strong radiation in space, the external environment of low temperature and vacuum is not something that human beings can bear. According to relevant research data, due to the continuous expansion of the universe, the temperature in space is also decreasing, and the average temperature in space is now close to absolute zero.

Since space is full of so many external factors that are unfavorable to humans, if a person dies in space, what is the fatal cause of their death? Is it hypothermia? After all, we have seen similar scenes in many science fiction movies, where a person falls into outer space without any protection, and his body appearance is quickly frozen, and the person dies immediately.

However, in real situations, if a person goes into space without any protection, the cause of his death is an instantaneous drop in air pressure. In a vacuum environment in space, the air in the human body leaves the body due to air pressure, including blood and air in various tissues of the body. From another point of view, the blood in our body seems to be "boiling" in an instant, which is undoubtedly an instantaneous fatal factor for humans.

Therefore, if humans want to enter space, they must be protected by spacesuits. Spacesuits provide us with the oxygen we need to carry out vital activities, while helping us block a lot of strong and harmful cosmic radiation, and help the body maintain the balance of air pressure. It can be seen that human beings are really vulnerable in the cosmic environment, but fortunately we know how to use other things to protect ourselves.

What exactly happens when the human body is directly exposed to space and without the protection of a spacesuit?

First of all, the vacuum is absolute, there is no oxygen, and in addition to this, there is cosmic microwave background radiation, which is close to absolute zero, which means that space is cold, but this is a gradual process, and a second may not hinder it. Of course, if you get close to the star, it is hundreds of millions of degrees of heat, and once the human body gets close, it will directly turn into dust.

If an astronaut is in space without a spacesuit, it stands to reason that he will die in about a minute due to lack of oxygen. It is because the lack of oxygen significantly prevents blood circulation to the different organs of our body, most importantly the brain. The stranded astronauts will be unconscious for about 15 seconds.

He would be permanently "brain dead" in one minute, and within two minutes after that, all of his organs would fail due to lack of oxygen. Medically, this is defined as death by asphyxiation. So under normal circumstances, as long as they put on the spacesuit within a minute, or are pulled back into the capsule, then the astronaut can still survive.

And appearing in space without any protection, there are many factors that come into play: lack of pressure, lack of oxygen, lack of gravity, extreme cold, radiation in space.

Many people think that in space, the human body will continue to expand and explode directly, but ours is elastic and can be stretched. That's why we get fat and get pregnant, and then shrink again. In the process, our ** will maintain the pressure.

Therefore, in a second the astronaut will not burst in space.

As for the radiation in space, not a second will freeze him into a popsicle, because this is a gradual process, not a direct zero to absolute zero. So, if an astronaut takes off his spacesuit and is in space for a second, he will not be fine, just exposed to some radiation.

Astronauts are active in space, generally with cosmic rays, and weightlessness drifting away.

The universe is the most ordinary person, but the meaning of the representation is not to change the sky and everything that constantly rotates. The universe as we know it is only the appearance of the universe and the theory that exists on paper. There is a dangerous danger in the real universe that only those who truly own the universe know about.

Many people are unaware of the panic from Earth to space, even in a cramped cabin, with a companion. You can take yourself with you for the first time, go abroad, and leave home for the first time. No matter how much it does, then the people are always not enough.

What is the mortal danger of astronauts in space? Space decompression is one of the dangers.

The unknown is our fear itself, why aren't these astronauts afraid? Today, it's still not too safe to pursue a career. Leaving the role of the history book is only part of the success of those who try, and there are so many people who have been given life in the development of science that they will be forgotten forever.

They have experienced despair of the throne before, and we may never know.

1.As soon as it unexpectedly breaks away from the female carrier: humanity will be "frozen into a pot" in space.

Space is a space devoid of particles, and unlike dusty dust in the air, astronauts appear in a space without protection, and without heat transfer from gaseous particles, they will freeze directly. The space environment is a good body insulating material. It warms the body in a thermos.

2. In zero gravity, burn alive.

If there is a fire in space, you will never see the usual burning flames on Earth, only the burning, confused "still" flames. But they also spread to many flammable installations. The space chamber is quickly filled with toxic air, and in the event of an air fire, the astronaut could be suffocated by the gas or through this strange zero-gravity flame.

3. Death in space, the most desperate way: stop on other planets and starve to death.

If an astronaut lands on a spacecraft on another planet and the spacecraft's engines suddenly "fail", then you will be trapped on this planet forever and never return to Earth. Maybe not starved initially, or thirsty.

4. Bacteria from the infected unknown universe die.

When an astronaut arrives in an alien world, it becomes infected with a mysterious alien virus, or a terrifying alien bacterium, that human spacecraft brings back to Earth, leading to anthropogenic extinction. Scientists believe that some other stars in the solar system are perfectly suitable for breeding foreign microorganisms, such as Mars or jupitar oceans, because the human immune system has never encountered them. Therefore, humans do not have any innate immunity to these bacteria.

5.Space catastrophes are most likely: sudden space clothing One of the greatest dangers for astronauts is damage to the spacecraft or space clothing, which will lead to a rapid loss of pressure.

Because we live in small lives, we also adapt to the pressures of the planet. If you suddenly appear in space, the water in the human body will disappear immediately. That is, moisture in the eyes and mouth.

Lack of oxygen causes the body to lose consciousness within 10 seconds and die within one to two minutes.

If they do it, they may fall into space, which is very dangerous, and they may die and not be able to hold out for a minute. Because the body is exposed to space all the time, there is no air in it, and the temperature is very low, so there will be a lack of oxygen.

If they are active, they may fall into space, and if they are for a long time, they may die, and they will not be able to last a minute, because their bodies are exposed to space all the time, there is no air in it, the temperature is very low, and many rays are finally evaporated and died.

Infected Unknown Cosmic Bacteria Die: When an astronaut arrives in an alien world, it becomes infected with a mysterious alien virus, or a terrifying alien bacteria.

Damage to spacecraft or space clothing, which will lead to rapid pressure loss, space decompression, excessive pressure that cannot be withheld.

You will be hurt by some unknown things at any time, you will not be able to eat what you want to eat, you will be suffocated by lack of oxygen, you will be very traumatized psychologically, and it will be difficult for you to adapt to life on earth when you return to Earth.

Since there is almost no air pressure, your blood and body fluids will boil and then freeze afterward. Your tissues (**, heart, and other internal organs) will swell due to boiling body fluids.
