The main problem with whether the human body can survive the void is that space does not have the oxygen, pressure, and temperature that the human body needs.

If a human being is exposed to space without any measures, the first damage he will suffer is loss of pressure.

Although the human blood pressure can still maintain about 75 Torr when the external environmental pressure is zero, the boiling point of some substances will also drop because of the drop in air pressure.

This causes small amounts of fluid to evaporate, bubbles to appear in the blood, and damage to the brain, nervous system, and even death.

The human body will not explode because of this, at most the lungs will be blown up, because the lungs have stored too much air, and they will rush out of the body frantically because of the excessive pressure difference.

In this case, if you forcibly hold your breath for oxygen, there will really be an implosion, and the air will blow up the lung lobes and trachea, which will make people die faster.

So in the case of a loss of pressure, the best way is to exhale all the air at once and live a little longer.

In other words, if the human body is exposed to space, even if he is given an oxygen tank, his lungs will not be able to work.

In this way, you will immediately face a second kind of injury, lack of oxygen.

Not only do humans actively excrete gases, but under the loss of pressure, the body will passively evaporate and lose water, and the pores will also excrete some gases, thus making the lack of oxygen more rapid.

You may be able to hold air in your lungs for a few tens of seconds longer because your body fluids and blood contain oxygen. But in space, just ten seconds can make people go into shock and even die.

As for the third kind of injury, when humans can solve the problem of hypoxia, they need to face cold death.

This is actually the last danger that will come up in the end.

Although the space environment is very cold, because there are few molecules in space, close to a vacuum, so it is a good heat insulator, for people who are exposed for a short time, the heat will not leave the human body immediately, but will only take away part of the heat due to the evaporation of water on the body surface, and slow thermal radiation and other ways to make it feel cold, but will not freeze to death immediately.

This kind of injury lasts for a long time, and often people die of lack of oxygen first, and then slowly freeze again, and finally become a dehydrated dry corpse.

But in any case, people live in space for a maximum of ten seconds.

Being able to live for ten seconds means living longer.

Bell said: "Juggernaut, with your body, you can survive in space for a short time, and if you can solve the oxygen problem, you can even live for more than ten hours." That's because your body is too tough, and your skin locks in the rapid loss of water and gas, which makes your heat loss slow and the lack of oxygen slow......"

Bai Ge said: "I have stored a lot of air in my brain, which can directly breathe internally, and the oxygen problem is easy to solve. ”

"But the pressure problem can't be solved, although you can make the body constantly resist blood bubbles, body fluid evaporation, nervous system damage and other injuries, but in the case of zero external pressure, many organ functions of the body will no longer work." This is the shortcoming of human beings born in the atmosphere, too high air pressure can still rely on the strength of the body to support it, but too low air pressure is difficult to adapt. ”

"Super-fast regeneration can keep you resisting, but what about brain damage? Over-speed regeneration keeps repairing, and the brain is constantly damaged and repaired. To adapt to it, genes need to evolve themselves in such an environment over a long period of time. This time can be long, and would you be willing to spend all day in space in a trance, confused, with intermittent amnesia that is out of harmony with your body control?"

Bai Ge understands this, his body can indeed resist the space environment.

He wouldn't die even if the nuclear explosion was farther away, so how could he die because of the space environment?

What really bothered him was normal thinking. This is a problem limited by human genes, and although he will not die in an ultra-low-pressure environment, he will basically be in a half-brained state for a long time.

He has over-speed regeneration, but thinking is not always intermittent.

"That is to say, I only need to solve the problem of loss of pressure, this problem is solved, I will no longer have to worry about the pressure problem in the future, I can adapt to the low-pressure environment, and I will resist the high-pressure environment, and I can't bear it, but the physical strength is not in place. Bai Ge said.

Bell said: "That's it, the pressure problem is solved, everything else is a minor problem." Oxygen can be breathed in the cavity of the brain, and the loss of water and heat will be extremely slow due to the strength of your body. Even cosmic rays will be ignored because of your heat-absorbing properties. ”

The universe is full of rays, but no matter what kind of radiation, the essence is the propagation of heat. Radiation destroys cells, but Bai Ge's cells are the least afraid of heat. At best, it will be damaged by the impact of a large number of high subprimordial particles contained in the rays, but the body that can be exercised with the help of Bai Ge's nuclear explosion is no different from the breeze blowing on the face.

Bell continued: "Of course, some extreme environments within the planet, such as Venus is highly acidic...... It may cause you harm, but as long as you are strong enough, you can solve it. ”

Bai Ge smiled, this is one of the reasons why he likes to be physically strong, his own strength is fundamental, and many small hazards can be ignored.

"Got it, let's try it. You provide the plan, and I will operate it. Bai Ge said.

Bell immediately said: "The first plan is to increase the elasticity of your skin and bones through genetic modification, and remove nine out of nine pores, and only four to eight controllable pores in the whole body are enough......"

"Hmm, wait a minute! This plan doesn't work, change it!"

Bai Ge listened to the bell's plan, and the image of Buu suddenly popped out of his head.

Bell said: "I will try to avoid the impact on your human appearance, if successful, you will still have a human appearance, at most ......"

"At most, there is no hair, right! Your plan is very problematic!" Bai Ge strongly refused.

The bell was helpless, so he had to say: "Then would you like to have an exoskeleton?" Theoretically, it will not be like an insect, but a dozen special bones will be added to your head or tail vertebrae to make your body automatically pressurized in a low-pressure environment. ”

"Uh...... It's not good!" Bai Ge thought for a moment and refused again.

Next, the bell proposes more than a dozen schemes, which, although do not change the basic characteristics of the human being, will always make people change more or less slightly.

After Bai Ge thought about it carefully, he passed it all.

Eventually, the bell said, "I only have one last option, and it will make your hair ......"

"What's the hair again!okay...... Since it is the last plan, for the sake of the stars and the sea, I have to give up my hair......" Although Bai Ge cherishes his hair very much, he still has the courage to give up at this moment. After all, even if he doesn't lose his hair now, as his pores get smaller and smaller, his hair will fall out sooner or later.

Bell said: "This time it's not about removing the hair, it's about changing the hair texture......"

"Oh, just change the hair, that's okay. Bai Ge felt that he finally had a good plan.

"Hair is the remains of dead cells in the human body, and I can modify the genes to make your hair follicles extend into active cells and be controlled by cranial nerves," Bell said. Not only does it add pressure to your skull, but it also changes its shape like you control your hands and feet. ”

Bai Ge understood, and said with a thought: "That is to say...... I don't have hair on my head, but flesh?"

"It's not all meat, it's a small amount of bone and spongy ......," Bell said.

"Isn't that a tentacle?" Bai Ge said with a raised brow.

The bell said, "You have to understand it like this, but in fact, it should be...... Well...... It is an extension of this organ that regulates the pressure in the body and is not affected by the low pressure of the outside world. I try to make it black so that on the surface, it will look like hair, and you can even change your hairstyle whenever and wherever you want, because it is an extension of your limbs...... Note that if you trim it, it will bleed ......"

Bai Ge clapped his hands and said: "Very good, that's it, basically there are only benefits! Not only does it solve the problem of loss of pressure, but it also adds an extra kind of limb by the way!"

"Actually, it's not a limb, it's a continuation of your intracranial muscles at best." And it's not without its drawbacks, if you're emotional, you're likely to get congested, and you have a nervous self-response like a 'knee thump'......"

Bai Ge smiled: "It's all a small problem, it can be fake, it's better than no hair, just work hard according to this plan!"

Bell said: "Okay, the stele will back up your genes at the moment, I will keep trying to modify them, if you make a mistake, you will have a genetic collapse, but you will not die." If you get it right, but you don't necessarily succeed in achieving this effect, you're likely to become something else. Either way, I'm going to keep a detailed record and reset your genes until I have a pattern to achieve that effect. ”

Bai Ge said with a smile: "In other words, if you are lucky, maybe the east will not be bright, and the west will be bright." What other strong genes did you intend to make?"

The bell said: "There is this possibility, in short, all rational genes, as long as you try it out, the stele will be recorded." The more we do, the more material we can study, and the more material we have, the more ideas and directions, and the more correct the rules we will summarize, and then there will be more materials that can be studied......"

"The more you know, the more you don't know. The study of genes is a long road, and we are only just getting started. ”
