Chapter 145 Acceleration Buffer

If humans continue to move forward on the path of design evolution, they may be able to carry out specialized transformation of parts of the body.

Such as activating a certain gene, replacing a certain gene, so that the human eye has the same night vision function as cats, and can switch at any time.

Of course, this is just one of them, there are other abilities of earth creatures.

Among the many technological advances, the most surprising progress is the acceleration buffer.

It was thought that the acceleration buffer could be realized after the body was strengthened. In the 17 years on earth, humans overcame the last technical difficulties and successfully produced this liquid.

But after experiments, it was found that the acceleration buffer was not as perfect as imagined.

Yes, the acceleration buffer has been successful in principle. This liquid is rich in oxygen. In clinical trials, it can also fill the entire lungs of people with liquid, and then fill various organs in turn, so that people can breathe in the acceleration buffer.

But this process is very painful. Many experimenters have experienced various adverse reactions to varying degrees in the process of filling various organs with liquid.

Such as suffocation reaction, vomiting reaction, breathing difficulty, etc.

The first two are the self-defense mechanisms of the body's functions, which can be solved through certain training, but the latter is a problem of respiratory system strength, which is a little troublesome. However, the problem is not very big, because scientists have found that this is due to the change of the breathing medium from gas to liquid, which causes a large amount of liquid to quickly pass through the narrow nasal cavity to form resistance. This problem leads to the fact that the muscles required for people to breathe in liquid are theoretically greater than those in air.

Finally, after the experimenter was replaced with a human in the peak state of human beings, this problem was solved.

In other words, the acceleration buffer has completely solved the problem of liquid breathing.

However, since this liquid is called an acceleration buffer, breathing is not its main problem. Its main problem is buffering, which is the fundamental problem and the problem of the imperfection of the acceleration buffer.

Because in order to have a buffering effect, the acceleration buffer must have five characteristics.

The first one is breathing.

This technical difficulty is the least, no problem.

Second, it can replace body fluids to participate in the circulatory system.

This is one of the basic conditions to ensure human survival in it. The technical difficulty is greater than breathing, but it has also been solved.

Third, the acceleration buffer will not be compressed. This is the most basic property of this type of liquid, because if the liquid can be compressed, then the compression rebound is enough to kill humans, so it also has no anti-high G acceleration effect.

This can be said to have been achieved when the acceleration buffer was declared successfully prepared.

Fourth, liquid can fill the human body's cavities that originally had no body fluid, such as the chest cavity, joint cavity, abdominal cavity, pelvic cavity, brain cavity, and organs with cavities, such as the stomach, duodenum, bladder, gallbladder, uterus, etc.

If any of these cavities is not filled with liquid, once the acceleration is accelerated, it will still be damaged by centrifugation, and the ruptured ones will rupture, and it will not play a protective role.

Among them, the technical difficulty of solving the problem of filling the brain cavity with the acceleration buffer is the greatest. Well. The side effects of the acceleration buffer in the brain cavity have been solved, otherwise it cannot be said that the research of this liquid has been successful. So the main reason is that the brain is too delicate, and there is no way to fill the brain cavity directly by injecting liquid into a chamber.

The phrase "water in the brain" is often used to describe a person with a problem in the brain, but the actual situation is that it is really difficult to let a person's brain be filled with water through the mouth and nose.

Because the brain cavity or cranial cavity is a closed cavity, it is impossible for liquid to penetrate directly into it.

In order to solve this problem, scientists proposed that it can be injected with a fine needle. But in this way, each person must be equipped with a special device, and it must be done once every time acceleration is performed, which is very troublesome and unsafe.

If the buffer is not injected into the brain cavity, then according to the data, the effect of the acceleration buffer will be greatly reduced, and its protection limit will jump directly from 120G to 80G.

The cranial cavity is a difficult problem to solve.

Filling the uterus is an extremely troublesome problem. In short, most women are very reluctant to do so. You can imagine this yourself.

Therefore, the successfully developed acceleration buffer cannot completely solve the problem of high-G acceleration faced by humans, and cannot allow human spacecraft to perform at the highest performance.

There is one last point, which is the fifth point: this liquid can make the human body density balanced.

This is a problem of human nature itself and cannot be solved.

Because humans cannot make the acceleration buffer have fantasy properties, after soaking people in it, the density of various parts of the human body becomes uniform.

It is not difficult to imagine that the density of human bones is different from that of other parts. Although the acceleration buffer can balance the pressure inside and outside the human body, as long as the density of the human body is different from that of the acceleration buffer, once the spacecraft is running at full speed, the person will still be thrown into a centrifuge, and the high-density bones will be separated from the human body, causing people to die directly.

Speaking of centrifuges, by the way.

In the process of separating plant cells with a differential centrifuge, you only need to let the centrifuge rotate to reach an acceleration of 150G and last for 20 minutes, then you will get a complete cell.

Once this acceleration exceeds 174G, the cell will rupture. As a cell, it can also be said that the maximum acceleration that human cells can withstand is 174G.

Of course, since the fifth point cannot be solved, the human body does not have the opportunity to reach the cell tolerance limit.

So now it can be made clear that the maximum instantaneous acceleration of bone and flesh separation is the protection limit of the acceleration buffer.

So what is this value for humans now?

The answer is 77G. This is the tolerance of humans after various existing biotechnologies have reached the peak state of the human body. Of course, this is when the acceleration buffer protects other organs of the body.

In other words, the emergence of the acceleration buffer allows people's fleets to accelerate and decelerate at a maximum of 77G.

So, the acceleration buffer was successful, but not completely successful.

The main problem, the fundamental problem, still goes back to the human body.

However, it does not mean that it cannot be solved, because humans still have body strengthening plans, and there are only body strengthening plans.

It is precisely because humans still cannot exert the maximum performance of warships after the emergence of the acceleration buffer that the new government decisively adjusted the key scientific research direction in the following time and officially put body strengthening at the top of future work.

At the same time, it is also the reason why the acceleration buffer is not ideal. The last voice of human society's resistance to design evolution has finally disappeared.

At this point, human society has broken through the final ethical issues of gene editing and concerns about its double-edged sword nature, and has officially embarked on the path of drastic changes to its own genes.
