Is there a mysterious force in space?

Astronauts were interviewed when they returned to Earth, and many of them said they experienced strange hallucinations in space, some of them even bizarre.

For example, the former Soviet cosmonaut Volkov once heard a dog barking in space. Where did the dog come from in the space capsule?

So how did the astronauts' "weird hallucinations" come about, and are aliens really influencing them?

The astronaut Experience

Almost every astronaut has been asked if he or she has seen a UFO, and astronauts have different experiences.

When Apollo 11 landed on the moon, it was rumored that the crew had been warned by a mysterious force and stayed inside for 10 hours until the force was gone.

Astronauts aboard the International Space Station have been caught on camera on a mission outside their capsule.

Astronaut Yang Liwei once heard a knock on the door when he was in space. You know, he was in space alone. No one would knock on the door.

So is it possible for astronauts to hallucinate?

In real life, the average person will have some hallucinations, such as hearing an acquaintance call them, but when they turn around to find no one.

Or when you go to the bathroom after watching a scary movie, you always feel something following you.

There are many reasons for hallucinations, such as stress, fatigue, alcohol, etc. It is caused by the abnormal production of dopamine in the brain, because dopamine will overexcite the brain, resulting in hallucinations.

In addition, hallucinations can occur when the brain is diseased, as in schizophrenia.

Astronauts are people too, and some of the symptoms that people experience on Earth can also occur in space.

First of all, the weightlessness of space makes the brain work differently in space than it does on Earth. Therefore, the dopamine production of astronauts will be different from that on Earth, and hallucinations will be normal.

Secondly, astronauts are always highly focused, and a task can take hours to complete. Such intense work makes astronauts tired, and they are also prone to hallucinations.

Finally, before entering space, astronauts have received relevant knowledge about Ufos and aliens, which also has a certain psychological implication for astronauts.

In addition, the spacecraft will make some sound when it is operating, and the capsule is not a vacuum, so it can transmit sound.

Suddenly hearing a sound in space really does capture the imagination of highly focused astronauts.

Yang Liwei heard a knock on the door of his cabin in 2003, as if someone was hitting a bucket with a stick, which became an unsolved mystery at the time.

After careful study by our aerospace engineers, the reason was finally discovered after 11 years.

It turns out that the temperature difference in space is so great that the temperature of the side facing the sun can melt all organic matter, and the side facing the sun can reach minus 200℃.

The materials for the spacecraft must be highly resistant to heat and cold.

However, no matter what material, under such a huge temperature difference will appear certain deformation.

Deformation is divided into macro deformation and micro deformation, the material deformation of the spacecraft will certainly not affect its normal operation, but because of such deformation, it will make a certain sound, after transmission into the ears of Yang Liwei.

Under such a high intensity of work, hallucinations are normal, which also shows that astronauts work very hard.
