Chapter 24: Ecstasy

There were more than 3,000 participants in the whole meeting, all of whom were the most elite. Yu Yifeng sat at the front of the hall, and there were more than 20 scientists sitting with him. They were the main persons in charge of various experiments.

The crowd was discussing quietly below. Many people were attending for the first time and did not know the truth. When they heard the bad news at first, they suddenly turned pale. Later, when they heard that there was still some hope, they felt a little better.

Yu Yifeng observed carefully and found that several familiar faces in the morning were gone. These people were caught for spreading rumors secretly and were all sent to prison.

Faced with this phenomenon, he was a little helpless and smiled bitterly in his heart. Perhaps this is the "suppression of dissidents" in politics, but there is no way. It is impossible to make everyone panic and lose their focus on work, right? He thought he was the righteous party, and perhaps those who were arrested also thought they were righteous...

"The meeting starts now!"

Yu Yifeng said solemnly, "Comrades, everyone knows the difficulties we are facing. We still have six months of safety time, so I won't say much. Now, the most critical issue 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 guard it tightly to gain the last chance of survival! If it is relatively small, we can rely on this spacecraft to escape from the moon!"

"Our scientists have measured the mass of the alien spacecraft. Now, please ask them to announce the final results!"

Everyone's eyes were looking straight at the stage. This was a kind of uneasiness and tension. This mood was like the last second before the college entrance examination results came out, entangled and uneasy, as if waiting for the verdict of fate. Now this uneasiness is a hundred times stronger, this is a verdict of life and death!

In fact, Yu Yifeng's heart was also a little uneasy. The expressions of these scientists were weird, and they could not see their joy, anger, sorrow or happiness. Some even frowned and looked sad, but Yu Yifeng could see that this was not worry, but a kind of doubt and confusion.

What was going on?

A scientist stood up and looked at so many people staring at him. He looked a little restrained. "Everyone, we used more than 20 methods to measure and got almost the same results. Its mass is..."

"1.0386 million tons!"

1.0386 million tons! "Wow", everyone became noisy and discussed the possibilities represented by this number.

Is it more? Less? Good? Or bad?

To be honest, the number of 1.0386 million tons is much better than the worst guess, but slightly worse than the most optimistic result. Some people even said that its mass is 0.

Yu Yifeng frowned. How should I put it? This alien spaceship is so huge, but if it is just this mass, it can be said to be very light, right?

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 mass of the 443.7-meter-high Empire State Building reaches 400,000 tons!

And a spaceship that is taller than Mount Everest is only a little over 1 million tons. It can only be said to be very light! Even if it can fit tens of thousands or hundreds of thousands of aircraft carriers, it is not a problem!

But, but... people don’t even have the ability to launch an aircraft carrier into the sky! The most prominent difficulty is the fuel problem. With the current chemical technology, if you want to propel a spaceship into the sky, you need at least ten times the mass of fuel.

The kinetic energy that a spaceship can obtain is not proportional to the amount of fuel. Under ideal conditions, 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 speed of the spaceship may only increase a little bit.

This is a headache for spaceflight. The most advanced Victory spacecraft weighed at least 5,000-6,000 tons when it was first launched, but it only weighed 500 tons in the end, which is still a relatively good result.

So how much fuel does a million-ton spacecraft need, 10 million tons? Do we need air circulation devices, power devices, etc.? What is the final speed? Can humans make an engine with a thrust of 10 million tons?

These are all problems, big problems!

Just as people were discussing, physicist Felix suddenly stood up, waved his hand, and said, "Everyone, listen to me, during the experiment, we found more than just this!"

"The number of 1.0386 million tons is actually much lighter than we thought! Why? Over the years, we have built hundreds of laboratories of various sizes in the spacecraft, and the materials and facilities moved in alone are far more than this number!"

"We made a simple estimate. In the past 30 years, we have moved in at least 2 million tons of things from the outside world! But the total mass measured is only 1.0386 million tons!"

"This is unreasonable! It's weird! It's even impossible!"

"We thought we had made a mistake, but more than 20 experimental methods have produced almost the same results. It's unimaginable! Unless the entire physics building is completely torn down and rebuilt, we will be completely wrong!"

"So, this spaceship must contain high technology that is unimaginable to us humans... In order to verify the idea in our hearts, we did a simple experiment."

"We first transported 10,000 tons of ore in the spaceship. Then we measured the mass of the spaceship again, and it was still 1.0386 million tons!"

"It's amazing. We don't believe in evil. We transported another 10,000 tons in, and it was still 1.0386 million tons!"

"What does this mean?" Felix said enthusiastically: "The mass of the spaceship is actually constant! No matter how much stuff is stuffed in it, it will not get heavier. My God! What kind of technology can do this?"

The hall was lively again. Some people understood it, and some people didn't understand it yet.

Yu Yifeng rubbed his nose. As long as those who understood it, there was a hint of ecstasy in their eyes!

What does it mean? To give a simple example, this spaceship is like a space ring in a fantasy novel. No matter how much stuff is put in it, it will not get heavier when weighed from the outside!

You have seen Doraemon. His space bag is filled with so many things, but it is still very light... This spaceship may be like this.

This is cheating! For interstellar travel, the most troublesome thing is fuel. For ordinary rockets, the mass of fuel alone accounts for 90% of its total mass, or even more than 95%!

For example, the Saturn V, the most powerful rocket ever launched by mankind, had an initial mass of 3,000 tons, but the Apollo spacecraft launched in the end was only 46 tons. According to the Tsiolkovsky rocket equation, most of the energy is actually used to propel the fuel "itself", so the energy utilization rate is actually very low.

It is precisely because of this that the speed of the spacecraft is so difficult to increase. With more fuel, its own mass is also larger, and only a little bit can be effectively used in the end.

To obtain greater kinetic energy, either more fuel or fuel with higher energy density, such as nuclear energy.

But now, the most fundamental and real cheating artifact has appeared, with a constant mass of 1.0386 million tons! No matter what you put in, the mass outside will not change. Even if you put in 100 million tons or 1 billion tons of fuel, it will still be 1.0386 million tons when you weigh it outside!

If you have the ability, you can put half of the moon in, 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? Humans don’t understand why there is such a wonderful phenomenon. This is not the world in fantasy novels...

However, even if you don’t understand, it doesn’t affect the use. Yu Yifeng only knows that he can put the entire lunar base in. He doesn’t need to consider weight or mass. He just needs to put things in like crazy!

Thinking about it, his eyes are getting brighter and brighter. If humans can’t escape the moon with such a spacecraft, they might as well die...
