Infinite Life: Trapped in a lifetime

As the smart era continues, the problems that long-distance voyages will face are:

Maybe it wasn't after waking up from this hibernation that mankind began to think after entering the intelligent age.

Starting from this life, and even earlier, there was also the life where the Institute of Exploration existed,

Thinking about this issue has already begun.

Further research directions in energy technology,

It is always relatively certain,

Other more imaginative sources of energy are too illusory.

The only one that is more reliable is the next generation, the third generation of controllable nuclear fusion technology, heavy nuclear fusion.

Relying on the technology accumulation of first-generation deuterium-tritium fusion and second-generation helium-3 fusion,

At least have some basic understanding of the theory of heavy nuclear fusion.

땤Unlike some more micro-level energy release methods, there is no margin at all.

However, it is also extremely difficult to realize heavy nuclear fusion.

From the reaction temperature alone, we can probably get a glimpse of some difficult manifestations.

The critical temperature of deuterium and tritium fusion is probably tens of millions of degrees.

땤Helium 3 has already risen to hundreds of millions of degrees.

As for the heavy nuclear fusion that we want to realize now,

The reaction temperature may be billions of degrees.

It can be said that it has climbed to another level.

땤This is still an estimate. How much temperature is needed in the actual experiment cannot be determined yet.

땤놇At the reaction temperature of billions of degrees, before the deuterium-tritium fusion was realized, many problems in the realization of controllable nuclear fusion have been solved.

The initial difficulty was how to achieve ignition at such a high temperature.

If you want to lower this temperature, you need to increase the internal pressure of the reactor. How to continue to pressurize?

놇Under the current performance of related materials, the pressure during the helium 3 reactor reaction process is already the limit. This is ultimately a material issue.

Then,

Even if you can light a fire,

How to constrain, maintain, and control reaction temperatures of billions of degrees?

The complete confinement scheme that relies on room temperature superconducting materials in helium 3 reactors is already the limit of what is currently technically possible.

Now we need to climb another level.

The most critical thing is that in the end, this third generation of controllable nuclear fusion and heavy nuclear fusion reactors will need to be installed on long-distance spacecraft.

This is also a difficulty.

땤놇In addition to energy,

On the issue of speed,

is more complicated.

How to realize the propulsion of a very large spacecraft at 8% of the speed of light and maintain it for decades.

Curvature engine, a true propellant without working fluid?

놚Can you really achieve one of them?

Many problems are quite simple.

It can even be said that not only the solar system, but also a wider range and a wider star field,

Human civilization has the foundation for rule and development.

However, the curvature engine, or the engine without working fluid, is even more out of reach.

Even now, in the era of intelligence,

껩 still can’t see any possibility of realization, even, as of now,

There are no truly feasible theories.

놇When thinking about this question,

Mo Dao thought of He Huai, his undergraduate roommate from his previous life.

껩 is someone who wants to devote himself to the research of grand unified theory,

땤In this life, up to now, the grand unified theory has still not been realized.

땤The biggest difficulty that blocks the unified theory is the attraction of gravity among the basic forces.

If you want to implement a curvature engine, at the very least, you need to implement a grand unified theory.

Going forward, if we want to take advantage of curvature, human civilization will at least be able to feel the warp in space.

For this kind of research, it is good to have a large number of problems to be solved.

The biggest problem is that there are no problems to be solved at all, because there is no direction and it is impossible to even ask questions.

final,

Mo Dao and the related fields team of Qiusuo Research Institute,

The choice is still the most practical direction.

It is a breakthrough in current electric propulsion technology.

Try to significantly reduce the working fluid required during its advancement.

In fact, its "push to weight ratio" has been greatly improved.

The best option is actually to link it with the energy system, that is, there is still not much progress at the moment with heavy nuclear fusion reactors.

Using by-products from the heavy nuclear fusion process as working fluid,

This can actually create a situation where the long-distance spacecraft does not need to carry additional propulsion fluid separately.

However, even if it is decided to continue to advance this route through electricity,

But the current situation has basically proven that

Under the existing basic framework of electric propulsion engines, the possibility of realizing the electric propulsion system envisioned by Modao and Qiusu Research Institute is very low.

껩That is to say, 놇The most basic theoretical structure used in the electric propulsion engine from room temperature -1 to the most advanced room temperature -6 now must be broken.

Reconstruct a new electric propulsion engine framework that can meet the needs of Mo Dao and Qiusu Research Institute,

This basic framework is not only about the appearance, but also about the internal structure.

땤 is to delve down to the theoretical level,

It is equivalent to the difference between tokamak and stellarator in the field of controllable nuclear fusion.

Although the overall design plans of deuterium-tritium fusion and helium-3 fusion are completely different, the most basic implementation theory is the same.

땤Electric propulsion engine, 껩 is in the same situation, from room temperature one to room temperature six, it is theoretically continued.

But now it is necessary to break completely and find a new path.

One can imagine the difficulties involved.

In addition, this newly constructed electric propulsion engine will inevitably require the support of a more powerful new material.

Otherwise, forget about pushing the spacecraft to accelerate to eight percent the speed of light.

I couldn't hold it while accelerating.

At the same time, the design of this new structure requires a new material to support it.

It is like the third material of room temperature superconducting material to the room temperature series electric propulsion engine.

so,

놇Since this period of time, Mo Dao has faced two problems in these two fields at this moment,

Most of the time, I still do research on material issues.

…

놇After the intelligent era,

When looking into the materials research field of the institute, Sui Gu꿰극 is the basic one.

놇Mo Dao here basically means that Mo Dao draws a range on a theoretical level.

Then it was handed over to Suigu for exhaustive experiments.

This can be regarded as the advantage of the intelligent era.

Not only data simulation, but also specific experimental operations can be completed by Suigu by operating several intelligent robots or intelligent equipment at the same time according to the determined experimental process.

Then after collecting relevant data, return it to Mo Dao.

Then Mo Dao did some more thinking about the data,

After re-drawing a range.

Then proceed to the next round of material testing.

땤Even with the assistance of 놇Suigu, this part of the experimental work has been much faster. The research on materials has been stuck in Mo Dao for more than ten years.

Mo Dao just customized a few materials from the vast sea of ​​materials for the new electric propulsion system.

…

In addition, Mo Dao has never given up on theoretical research on the realization of heavy nuclear fusion.

At least, based on his turbulence theory, he needs to give him a more perfect model to apply the constraints of heavy nuclear fusion.

As for the electric propulsion engine, he needs to lead the relevant research team of the Research Institute to complete a new structure that is at least theoretically feasible.

Time, in this process, keeps passing by.

70 years, 71 years.

Mo Dao was not very impatient. He was just relatively calm every day, thinking about the same problems over and over again and trying them from different angles.

Under the chairmanship of Mo Dao, researchers from relevant teams in various fields are not too impatient. They always have some blind confidence in Chief Mo.

In addition, for Mo Dao, the progress is slow. For a group of researchers, it is exciting enough for such a super project to feel that it is always moving forward instead of always standing still.

땤For the public at Qiusu Research Institute, there is no need to worry. They can still feel that there are various new technologies that may not transcend the times, but the smart era is born every day, and life is still happening. changes.

Then,

In this case,

There are finally some opportunities to solve the two key issues in the voyage goal.

In 1973, Modao obtained a new room temperature superconducting material.

In addition to a higher critical temperature, it has considerable strength and excellent properties in many other aspects.

껩 is a masterpiece that Mo Dao has been researching for more than ten years.
