Beneath Deep Space

A total of more than 3,000 people attended the entire conference, all of whom were the most elite. Yu Yifeng sat at the front of the hall, and sitting with him were more than twenty scientists, who were the main persons in charge of various experiments.

The crowd was discussing quietly below. Many people participated for the first time and did not know the truth. When they heard the bad news at first, their faces suddenly turned pale. Later, they felt 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 was the "suppression of dissidents" in politics, but there was no way. We couldn't make everyone panic and have no intention of working, right? He thinks that he is the just party, and maybe those who were caught also think that they are just...

"The meeting starts now!"

Yu Yifeng said seriously, "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 smaller, 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, feeling uneasy and nervous. This feeling is like the moment before the college entrance examination results come 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 felt a little uneasy. The expressions of these scientists were strange, and they could not tell the joy, anger, sorrow, or joy. Some even frowned and looked sad, but Yu Yifeng could tell that this was not worry, but a kind of doubt and confusion.

What's going on?

A scientist stood up and looked a little restrained when he saw so many people staring at him. "Everyone, we have used more than twenty methods to measure and got almost consistent results. Its mass is..."

"1.0386 million tons!"

1.0386 million tons! With a roar, everyone became noisy and discussed the possibilities represented by this number.

How much is it? Is it less? Is good? Or 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 it has a mass of 0.

Yu Yifeng frowned. How should I put it? 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 mass of the 443.7-meter-high Empire State Building reaches 400,000 tons!

And a spacecraft with a height higher than Mount Everest only weighs a little over 1 million tons, which can only be said to be very light! Even if it can block tens of thousands or hundreds of thousands of aircraft carriers, it won't 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 issue. With current chemical technology, if you want to propel a spacecraft into space, you need at least ten times the mass of fuel.

The kinetic energy that a spacecraft can obtain is not directly 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 speed of the spacecraft may only increase a little.

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? Do we need additional air circulation devices, electrical devices, etc.? What is the final speed? Can humans make an engine with a thrust of 10 million tons?

All of these are problems, 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 just weird! It's even impossible!"

"We thought we had made a wrong measurement, but more than twenty experimental methods have produced almost the same results, which is unimaginable! Unless the entire physics building is completely redesigned, we will all make mistakes!"

"So, this spacecraft must contain high technology that we humans can't imagine... 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 a fantasy novel. No matter how many things are loaded inside, 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 a typical rocket, the mass of the fuel alone accounts for 90%, or even more than 95%, of its total mass!

For example, the Saturn 5, the most powerful rocket ever produced 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, most of the energy is actually used on 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. If there is more fuel, its mass will also be greater. In the end, only a little can be effectively used.

To obtain greater kinetic energy, either more and more fuel is needed, or fuel with greater energy density is used, such as nuclear energy.

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

This kind of 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 such a wonderful phenomenon occurs. This is not a world in fantasy novels...

However, knowing how to return 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...
