A total of more than 3,000 people attended the entire meeting, all of whom were the most elite. Yu Yifeng sat at the front of the hall, and sitting with him were more than 20 scientists, who were the main persons in charge of various experiments.
The crowd was discussing in a low voice below. Many people were participating for the first time and did not know the real situation. At first, they suddenly turned pale after hearing the bad news. Later, they felt a little better after hearing that there was still some hope.
Yu Yifeng took a closer look and saw that several familiar faces from the morning were gone. These people were caught secretly spreading rumors and were all sent to prison.
Faced with this phenomenon, he felt a little helpless and smiled bitterly in his heart. Maybe this is the "suppression of dissidents" in politics, but there is no way. We can't make everyone panic and have no intention to work, right? He thinks he is
The righteous party, perhaps those who were caught, also think that they are righteous...
"The meeting starts now!"
Yu Yifeng said sternly, "Comrades, everyone knows the difficulties we have encountered. Our safety time is still six months, so I won't say more. Now, the most critical thing is the quality of the alien spacecraft.
!”
"This issue is even related to our survival strategy! If the mass of the spacecraft is too large, we humans cannot push it, and we can only hide inside and defend it to win the last chance of survival! If it is relatively small, we can use this spacecraft to escape from the moon!
"
"Our scientists have measured the mass of the alien spacecraft. Now, please publish the final results!"
Everyone's eyes were looking straight at the stage, which was a kind of uneasiness and nervousness. This kind of mood was like the moment before the college entrance examination results came out, entangled and uneasy, like waiting for the judgment of fate.
.Now this anxiety is a hundred times stronger. This is a life-threatening sentence!
In fact, Yu Yifeng's heart was a little uneasy. The expressions of these scientists were strange, and they could not tell whether they were happy, angry, sad or happy. Some even frowned and looked sad, but Yu Yifeng could see that this
It's not worry, but a kind of doubt and confusion.
What is going on?
A scientist stood up. Seeing so many people staring at him, his expression was a little restrained. "Everyone, we have used more than twenty methods to measure and obtained almost consistent results. Its mass is..."
"1.0386 million tons!"
1,038,600 tons! There was a roar, and everyone became noisy, discussing the possibilities represented by this number.
Is it more? Is it less? Is it good? Or is it bad?
To be honest, the figure of 1.0386 million tons is much better than the worst guess, but slightly worse than the most optimistic result. Some people even say that its mass is 0.
Yu Yifeng frowned. How can I put it this way? This alien spacecraft is so huge, but with this mass, it can be said to be very light...
You know, the mass of a large aircraft carrier is about 100,000 tons, the mass of the Oriental Pearl Tower is about 125,000 tons, and the 443.7-meter-high Empire State Building has a mass of 400,000 tons!
And a spacecraft with a height higher than Mount Everest is only a little over 1 million tons, which can only be said to be very light! Even if it can accommodate tens of thousands or hundreds of thousands of aircraft carriers, it will not be a problem!
But, but... people don't even have the ability to lift an aircraft carrier into the sky! The most prominent difficulty is the fuel problem. With current chemical technology, if you want to propel a spacecraft into the sky, you need at least ten times the mass of fuel.
OK.
The kinetic energy that the spacecraft can obtain is not proportional to the amount of fuel. Ideally, it can be expressed by the Tsiolkovsky rocket equation. This is not a linear function. To put it simply, if the fuel increases a lot, the final result of the spacecraft will
The speed may only increase a little bit.
This is a troublesome problem in aerospace. The current most advanced Victory spacecraft weighed at least 5,000-6,000 tons when it first launched into space, but in the end it only weighed 500 tons. This is still a relatively good result.
So how much fuel does a million-ton spacecraft require? Ten million tons? What kind of air circulation device, electric device, etc. are needed? What is the final speed? Can humans make a propulsion of 10 million tons?
tons of engines?
All of these are problems, and they are all big problems!
Just as people were talking about it, physicist Felix suddenly stood up. He waved his hand and said, "Everyone, listen to me. During the experiment, we discovered more than this!"
"The figure of 1.0386 million tons is actually much lighter than we imagined! Why? Over the years, we have built hundreds of laboratories of various sizes in the spacecraft, and the material facilities we moved in alone are far more than
this number!"
"We made a simple estimate. In thirty years, we have moved at least 2 million tons of things from the outside world! But the total mass was measured to be only 1.0386 million tons!"
"This doesn't make sense! It's simply bizarre! It's even impossible!"
"We thought we had made a wrong measurement, but more than 20 experimental methods have yielded almost the same results, which is simply unimaginable! Unless the entire physics building is completely redesigned, we will all make mistakes!"
"So, this spacecraft must contain high technology that is unimaginable to us humans... In order to verify our ideas, we conducted a simple experiment."
"We first transported 10,000 tons of ore in the spacecraft. Then we measured the mass of the spacecraft, and it turned out to be 1.0386 million tons!"
"It's so surprising. We don't believe in evil. If we transport another 10,000 tons, it will still be 1,038,600 tons!"
"What does this mean?" Felix said enthusiastically: "The mass of the spacecraft is actually constant! No matter how many things are stuffed inside, it will not become heavier. Oh my God! What kind of technology can do this?
"
The hall became lively again, some people understood it, and some people still didn't understand it.
Yu Yifeng rubbed his nose, and anyone who understood would have a hint of ecstasy in his eyes!
What does it mean? To give a simple example, this spaceship is like a space ring in fantasy novels. No matter how many things are loaded into it, it will not become heavier when measured from the outside!
Have you seen Doraemon? His space bag contains so many things, but it is still very light... This spaceship may be like this.
This is equivalent to cheating! For interstellar navigation, the most troublesome thing is fuel. For ordinary rockets, the mass of fuel alone accounts for 90%, or even more than 95%, of its total mass!
For example, the Saturn 5, the most powerful rocket ever used by mankind, had an initial mass of 3,000 tons, but the Apollo spacecraft that was finally launched was only 46 tons. According to the Tsiolkovsky rocket equation, the vast majority
Most of the energy is actually used in the propulsion fuel itself, so the energy utilization rate is actually very low.
It is precisely because of this that it is so difficult to increase the speed of the spacecraft. The more fuel, the greater its mass, and in the end only a little can be effectively used.
To obtain greater kinetic energy, one must either use more fuel or use fuel with greater energy density, such as nuclear energy.
But now, the most fundamental and true cheating artifact has appeared. The mass is constant at 1.0386 million tons! Whatever you put inside it, the quality outside will not change. Even if 100 million tons or one billion tons of fuel are installed, the outside weight will not change.
, or 1.0386 million tons!
If you have the ability, you can fit half of the moon into it without any problem, and the mass will still be 1.0386 million tons!
Such technology is really abnormal! For humans, it is no different from cheating. Is this space technology or negative matter technology? Human beings simply don’t understand why there is such a wonderful phenomenon. This is not a world in fantasy novels...
However, knowing how to store it does not affect its use. Yu Yifeng only knows that he can fit the entire lunar base into it. There is no need to consider the weight or quality, as long as he packs things crazily!
As he thought about it, his eyes became brighter and brighter. With such a spaceship, if humans can't escape from the moon, they might as well die...
