A total of more than 3,000 people participated in the entire meeting, all of whom were the most elite. Jack 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 discussed in low voices below. Many people participated in the event for the first time and did not know the truth. At first they turned pale when they heard the bad news, and then they got better after hearing that there was still some hope.
Jack took a closer look, and all the familiar faces were gone. These people were arrested for spreading rumors secretly, and all of them went to prison.
Faced with this phenomenon, he was a little helpless, and smiled wryly in his heart. Maybe this is the "suppression of dissidents" in politics, but there is no way, it can't make everyone panic and have no intention of working, right? He thinks that he is the righteous party, and maybe those who were caught in it also think that they are righteous...
"The meeting starts now!"
Jack said sternly, "Comrades, everyone knows the difficulties we have encountered. Our safety time is still six months away, so I won't say much. 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 spaceship is too large, we humans can't push it, so we can only hide in it to guard against death and win the last chance of life! If it is relatively small, we can use this spaceship to escape from the moon! "
"Our scientists have measured the mass of the alien spacecraft, now, please announce the final results!"
Everyone's eyes were looking straight at the stage, which was a kind of uneasiness, a kind of nervousness. This kind of mood is like the second before the results of the college entrance examination, entangled and uneasy, as if waiting for the judgment of fate. Now this anxiety is a hundred times stronger, this is a life-and-death sentence!
In fact, Jack was also a little restless. The expressions of these scientists were all weird, and they couldn't see any emotions. Some even frowned, with a sad look on their faces, but Jack could tell that this was not worry, but a kind of doubt, a kind of perplexity.
What is going on?
A scientist stood up, seeing so many people staring at him, his expression was somewhat restrained, "Everyone, we have used more than 20 methods to measure and obtained almost consistent results. The quality is..."
"1.0386 million tons!"
1.0386 million tons! With a "wow", everyone became noisy, discussing the possibility 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 its quality is zero.
Jack frowned. How should I put it, this alien spaceship has such a huge volume, 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 weighs more than 1 million tons , so it can only be said to be very light! Even if it packs 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 problem of fuel. With the current chemical technology, if you want to propel a spaceship to the sky, you need at least ten times the mass of fuel.
The kinetic energy that the spacecraft can obtain is not directly proportional to the amount of fuel, and ideally 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 vexing problem in spaceflight. The most advanced Victory spacecraft was at least 5,000-6,000 tons when it first ascended, but it was only 500 tons in the end. This is a relatively good result.
So how much fuel does a million-ton spaceship need, 10 million tons? Do I need to add some air circulation devices, electrical devices and the like ? What is the final speed? Can humans make an engine with a driving force of 10 million tons?
Each of these is a problem, a big problem!
When people were discussing, the physicist Felix suddenly stood up, 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, large and small, in the spacecraft, and the materials and facilities that have been moved in are far more than this number!"
"We made a simple estimate. In 30 years, we have moved at least 2 million tons of things from the outside world! But the total mass is only 1.0386 million tons!"
"It doesn't make sense! It's just weird! It's not even possible!"
"We thought we made a mistake, but more than 20 experimental methods have obtained almost the same results, which is unimaginable! Unless the entire physics building is pushed back, we will all make mistakes!"
"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 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, and if we transport another 10,000 tons, it will still be 1.0386 million tons!"
"What does this mean?" Felix said frantically, "The mass of the spaceship is actually constant! No matter how much stuff is stuffed into it, it won't get heavier, my God! What kind of technology is this possible? "
The hall became lively again, some people understood it, and some people didn't understand it.
Jack rubbed his nose, as long as he understood, there was a hint of ecstasy in his eyes!
What do you mean? To give a simple example, this spaceship is like a space ring in fantasy novels, no matter how many things are put inside, it will not become heavier when weighed from the outside!
Doraemon has seen it, his space bag, which contains so many things, is still very light... Maybe this spaceship exists like this.
This is equivalent to cheating! For interstellar navigation, the most troublesome thing is fuel. In a normal 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 human rocket ever, had an initial mass of 3,000 tons, but the final Apollo spacecraft was only 46 tons. According to the Tsiolkovsky rocket equation, most of the energy is actually used on the propellant "self", so the utilization rate of energy is actually very low.
It is precisely because of this that it is so difficult to increase the speed of the spacecraft. With more fuel, its own mass will also increase, and only a little bit can be effectively used in the end.
To obtain greater kinetic energy, either more and more fuel is used, or fuel with higher energy density is used, for example, nuclear energy.
But now, the most fundamental and true cheating artifact has appeared, with a constant mass of 1,038,600 tons! The contents inside can be loaded casually, and the quality of the outside will not change. Even if 100 million tons or one billion tons of fuel are loaded, the outside weight is still 1.0386 million tons!
If you have the ability, there is no problem putting half the moon in it, and the mass is still 1.0386 million tons!
This kind of technology is really perverted! 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, if you don't know what you don't understand, it doesn't affect the use. Jack only knows that he can put the entire moon base in it. He doesn't need to consider the weight or quality, as long as he loads things like crazy!
As he thought about it, his eyes became brighter and brighter. With such a spaceship, if humans cannot escape from the moon, they should just die...
