There are many records about Princess Wencheng in history, but almost no one knows about the origin of Princess Wencheng. There is still no detailed explanation. It is even impossible to say whether Princess Wencheng is the legitimate daughter of the collateral line of the Li family. It is possible that the maid may adopt a goddaughter.
All of this illustrates one point. Don't think about contracts or anything like that. It's useless. Big fists are the truth.
All contracts are forced choices made when both parties cannot physically convince the other party.
This is the current situation of mankind. There are more than 200 countries on one planet, and these countries are fighting against each other. But if one day, an alien civilization suddenly appears in front of the earth, and if mankind does not unite, all of them will be wiped out.
At this time, all racial conflicts and religious conflicts must be put to the end. I dare not say that the earth can be quickly unified into a country or a federation, but at the very least, there is absolutely no problem in forming a united front in a very short time.
If the two sides continue to fight against each other and sustain it for a long enough time, then it will be a matter of course for the earth to unify into a federal country.
Without pressure, everything is in vain unless the technological level of one country can suddenly be raised to the point where it can instantly defeat all other countries.
Even so, to be honest, if the country is given the choice at present, the country will not choose to engage in any unification or alliance.
Wouldn't it be nice to develop Daqin and the Song Dynasty world? Going a step further, wouldn't it be great to develop the moon and Mars?
When other countries fall behind to a certain extent and gradually penetrate their culture, and eventually eliminate the other country's culture, it will be difficult for the other country not to integrate.
Sometimes, that's how it is with each other.
Human life is too short. With a history of more than a hundred years, if there are wise enough leaders and some long-term plans are made, it will only take two or three generations to wipe out the other party's culture.
Aren't there many examples in China? There are too many useless youths who kneel down and never get up again. The contract only lasts for 99 years, but in fact it only lasts for 156 years.
Therefore, what Jiang Yan Hai is designing at the moment is more about how to return between space and the ground, and the design of the spacecraft in space.
These designs can be said to be unprecedented, and there are no examples to consult, because these designs relate to more than just a spacecraft issue. A spaceship must have a complete environmental adaptation system, and humans consume resources every day.
This is not just a matter of designing a spacecraft and providing sufficient power.
If the spacecraft's own internal circulation system cannot solve the problem, or if it is not solved, at least water and air can be solved by at least 50% through internal circulation. Only then can there be real long-term recycling and the possibility of mutual development among planets.
The second is the construction of bases on various planets, etc., all of which need to be considered.
Energy has only solved the most basic problems, and there are still many, many remaining problems.
But at the very least, China has come this far, right?
We are no longer just a matter of detection, we are ready to actually take this step.
Waiting for the emergence of this Mechanical Octopus, Jiang Yan Hai is constantly simulating and manufacturing these space planes that move between the ground and space in Illusion Simulation Program.
If there is enough power, it does not need to reach the first cosmic speed in a short time like a rocket to escape the gravity of the earth.
After entering space, the air there is thin. At this time, if enough thrust is provided, it will be easier to accelerate to above the first cosmic speed.
But how to choose between the two is difficult.
Because you continue to give the aircraft a fixed thrust, even if it is as fast as human walking, it can leave the earth. But the fuel and energy consumed continuously in this way are undoubtedly very huge.
It is impossible for a rocket to carry so much fuel, so the rocket must increase its flight speed as quickly as possible, but considering the weight of the transported object, there must be a qualified trade-off.
In fact, if you have Controlled Nuclear Fusion, this will be different. Just like the mainstream ion thrusters in the world now are electromagnetic, which is the same concept as the electromagnetic rail gun. It accelerates the plasma through the magnetic field to a certain ultra-high speed, and then ejects it from the nozzle, thereby bringing thrust.
However, because all current satellites and spacecrafts can provide limited power, the thrust that consumes electricity to provide magnetic fields to generate thrust is naturally extremely limited.
At present, it is only useful in space, and it is basically used for steering in space. Only some detectors released outside the solar system will use such a thing to operate the main thrust, because there is enough time for it to continue to run, and in the end, its speed can also reach an extremely high speed.
However, there is another type of ion thruster, which is the arc heating type. It actually places a point between two electrodes to form a high-temperature arc to heat the gas. After the gas enters the compression section of the anode nozzle, it is heated by the arc to a high temperature of more than 10,000K, that is, ionization occurs at a high temperature of more than 5,000 degrees Celsius.
Then the gas enters the anode nozzle and expands for a short period of time. The expansion accelerates to above supersonic speed, and finally it is ejected at high speed to form thrust.
The arc-heated ion thruster has great development prospects. Although its thrust\power ratio is lower than that of the electromagnetic thruster, it is many times higher than that of the chemical thruster.
In addition, its simple structure, low operating voltage, and long life are all advantages.
When the question comes to this point, everyone should understand one thing, that is, after having Controlled Nuclear Fusion, what is this arc-heated ion thruster? This thing still needs electric discharge heating, but don't forget Controlled Nuclear Fusion, it itself has extremely terrifying high temperatures! Just tell me how many degrees Celsius you want!
Its core temperature can reach 100 million degrees Celsius! If the temperature of Controlled Nuclear Fusion is used to generate electricity through the fusion reaction, its temperature can also heat the air and accelerate ions. This thing is simply the best of both worlds.
Otherwise, why is Controlled Nuclear Fusion the most important invention of mankind.
Now, what Jiang Yan Hai is engaged in is how to reasonably miniaturize Controlled Nuclear Fusion.
If it were turned into a robot-sized core like in a science fiction movie, then humans can't do it currently.
But if you enlarge it to a certain size, such as a huge size like An-225, to be honest, it can actually be done.
