Acceleration Buffer Fluid

If humanity continues on the path of Designed Evolution, it is not impossible to carry out specialized modifications to parts of the body.

Such as activating or replacing a gene segment, giving the human eye night vision like that of a feline, and being able to switch between them at any time.

Of course, this is just one of them; there are many other abilities of Earth's creatures.

Among the many technological advancements, the most exciting development is the Acceleration Buffer Fluid.

The Acceleration Buffer Fluid, which was thought to be achievable after physical enhancement, was successfully manufactured by humanity after seventeen years on Earth, as humanity overcame the final technical hurdle.

However, after testing, it was found that the Acceleration Buffer Fluid was not as perfect as imagined.

Yes, the Acceleration Buffer Fluid has been successfully developed in principle. This liquid is rich in oxygen, and in clinical trials, it has been used to fill the entire lungs with the liquid and then fill each organ in turn, thus enabling a person to breathe in the Acceleration Buffer Fluid.

However, this process is extremely painful, and many participants experienced various adverse reactions to varying degrees during the process of filling their organs with liquid.

Such as suffocation, vomiting, and difficulty breathing.

The first two are the body's self-defense mechanisms, which can be addressed through training. However, the latter is a problem with respiratory system strength, which is a bit more troublesome. But it's not a major issue, because scientists have discovered that this is due to the change in the breathing medium from gas to liquid, causing a large amount of liquid to rapidly pass through the narrow nasal cavity, creating resistance. This means that theoretically, breathing in liquid requires more muscle mass than breathing in air.

Finally, the problem was solved when the experimenter was replaced with a human in peak human condition.

In other words, the Acceleration Buffer Fluid has completely solved the problem of liquid respiration.

However, since this liquid is called Acceleration Buffer Fluid, breathing is not its main problem. Its main problem is buffering, which is the fundamental issue and the reason why the Acceleration Buffer Fluid is imperfect.

To have a buffering effect, Acceleration Buffer Fluid must possess five characteristics.

The first one is breathing.

This technique is the least difficult, there's no problem.

Second, it can replace bodily fluids in the circulatory system.

This is one of the basic conditions that ensures human survival inside, and the technical difficulty is greater than breathing, but it has been solved.

Third, the Acceleration Buffer Fluid cannot be compressed. This is a fundamental property of this type of liquid, because if the liquid could be compressed, the rebound from compression would be enough to kill a human, thus it has no resistance to high-G acceleration.

This can be said to have been achieved when the Acceleration Buffer Fluid was declared successfully prepared.

Fourth, fluids can fill cavities in the human body that do not normally contain bodily fluids, such as the thoracic cavity, joint cavities, abdominal cavity, pelvic cavity, and brain cavity, as well as organs with cavities, such as the stomach, duodenum, bladder, gallbladder, uterus, etc.

If any of these cavities are not filled with liquid, they will still be damaged by centrifugal force once the speed is increased, and they will still break, thus failing to provide any protection.

The most technically challenging aspect was solving the problem of filling the brain cavity with the Acceleration Buffer Fluid. While the side effects of the Acceleration Buffer Fluid within the brain cavity were resolved—otherwise, the research on this liquid wouldn't be considered successful—the main reason is that the brain is too intricate to be filled directly by injecting liquid into a chamber.

The phrase "brain full of water" is often used to describe someone who has a problem with their brain, but in reality, it is really difficult to make someone's brain full of water through their mouth and nose.

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

To solve this problem, scientists proposed using a fine needle for injection. However, this would require each person to have a specialized device, and the procedure would have to be repeated every time acceleration is performed, which is both inconvenient and unsafe.

However, if the brain cavity is not injected with buffer solution, data shows that the effect of the Acceleration Buffer Fluid will be greatly reduced, and its protective limit will jump directly from 120 G to 80 G.

The cranial cavity is a difficult problem to solve.

Filling the uterus is an extremely troublesome issue, and in short, most women are very reluctant to do it. You can imagine for yourselves that the Acceleration Buffer Fluid that was successfully developed cannot completely solve the problem of humans facing high-G acceleration, and cannot allow human spacecraft to achieve their highest performance.

Finally, and this is the fifth point: this liquid can help balance the density of the human body.

This is a problem inherent in human nature, and it cannot be solved.

Because humans cannot give the Acceleration Buffer Fluid a mystical property, the density of different parts of the body becomes uniform after being immersed in it.

It's not hard to imagine that the density of human bones is different from that of other parts of the body. Although the Acceleration Buffer Fluid can balance the pressure inside and outside the body, as long as the density of the human body is still different from that of the Acceleration Buffer Fluid, once the spaceship is running at full speed, the person will still be like being thrown into a centrifuge. The denser bones will detach from the body, causing the person to die instantly.

Speaking of centrifuges, let me mention them in passing.

In the process of separating plant cells using a differential centrifuge, you only need to run the centrifuge to reach an acceleration of 150G for 20 minutes to obtain intact cells.

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

Of course, because the fifth point cannot be resolved, the human body does not have the opportunity to reach the limits of cellular tolerance.

Now we can clearly define the maximum instantaneous acceleration of bone-flesh separation as the protective limit of the Acceleration Buffer Fluid.

So what is this value for humans today? The answer is 77G. This is the maximum tolerance humans can withstand after reaching peak physical condition using various existing Biotechnology. Of course, this is under the condition that the Acceleration Buffer Fluid protects other organs of the body.

In other words, the advent of the Acceleration Buffer Fluid allows human fleets to accelerate or decelerate at a maximum of 77G.

So, the Acceleration Buffer Fluid was successfully developed, but not completely.

The main and fundamental issue still comes back to the human body.

However, this does not mean that there is no solution, because humans still have body enhancement programs, and that is the only option.

It was precisely because humans were still unable to unleash the full potential of warships even after the advent of the Acceleration Buffer Fluid that the New Government decisively shifted its research priorities in the coming period, placing physical enhancement at the forefront of its future work.

At the same time, it was also the reason why the Acceleration Buffer Fluid was not ideal that the last voices of resistance to the Designed Evolution in human society finally disappeared.

Thus, human society overcame the final ethical concerns and double-edged sword nature of gene editing, and officially embarked on the path of drastically modifying its own genes.
