Radar operators of the Fifth Fleet found that two warplanes had disappeared from the radar. Pen ~ fun ~ pavilion www.biquge.info

At first, they thought that the radar was interfered with by the solar wind or clouds, or that it had dived into the radar blind spot, but after waiting for several minutes, the fighter still did not appear.

Tried to call the two fighters, but there was silence on the other side.

At this time, a spy satellite flew nearby, and they immediately logged into the satellite and launched a search.

Based on the time and flight speed of the two planes, as well as the possible targets of the two planes, they quickly confirmed the approximate place of the fall, and also successfully found the conspicuous umbrella flower hanging above the dense forest, covering the canopy of the primeval jungle, the smoke from the crash explosion in the distance, and ......

"Oh my God, what the hell is that!" the searchers immediately reported to their superiors, and then the image was transmitted back to the Pentagon as quickly as possible.

The silver-gray I-shaped guide rail, standing straight above the earth, is no more than a meter wide and half a meter thick, but the length is endless.

The track itself is actually as thin as a silkworm wing, but the I-shaped structure gives it a thickness of half a meter.

In the field of vision of the optical spy satellite, there is a bright band of light like a reflective band!

Blinding!

What the hell is this?

Then, almost the entire Pentagon, fell into a three-stage consternation.

Is this a space elevator?

OMG! This really is a space elevator!

OMG! The lazy god system actually built a space elevator!

On this day, the generals and experts who filled the building almost became the most devout believers, and they called more gods in one day than in a lifetime combined.

If there is a constant in nuclear physics, it is called "50 years before controlled nuclear fusion".

Then there is also a constant in the space industry, called "20 years before the space elevator".

Tsiolkovsky, the father of rocketry, proposed this concept in 1895, and for the next hundred years, it remained 20 years away from mankind, which has been advancing, but never approaching......

Until now, he suddenly appeared in front of everyone.

What is a Space Elevator?

If you ask an ordinary person on the street, I'm afraid you will look confused, and then guess: "Probably ...... Some kind of elevator. ”

Congratulations, you got it right, this is indeed a kind of elevator.

Everyone has taken the elevator, the sightseeing elevator in the shopping center, the ordinary elevator in the residential building, and the engineering car used in the project are all elevators.

It's essentially a rope plus a box that can hold people and goods, and then pulls it up and puts it down with various powers.

For every lazy person, the elevator is probably one of the cutest inventions in the world, think of a world without elevators, people have to climb several floors, dozens of floors or even hundreds of floors with their own feet...... Climb until you can't lift your legs, pant and look up, it's an endless loop of stairs, what a desperate world it will be.

It is estimated that many people just give up and jump from the floor they have already climbed.

In modern society, elevators have covered all aspects of human existence, but if someone tells you that there is an elevator that can drag things directly from the ground to outer space, you are like taking a sightseeing elevator, you can take the elevator to reach the space station in outer space, or even ...... Reaching higher and farther places, you must think that this is a special bragging.

So far, the tallest building built by human beings is the Lazy God Tower, which is more than 1,300 meters high, and if you climb the Lazy God Tower with both feet, it is probably equivalent to climbing Mount Tai once.

Before this, the highest is the Burj Khalifa, that is, the Burj Khalifa, as high as 828 meters, people who have seen Mission Impossible, will definitely sweat for Brother Tang hanging on the Burj Khalifa, which can not see the ground at a glance!

But the principle of the space elevator requires that its center of gravity must be in geosynchronous orbit, that is, its minimum altitude is ...... 3600 km!

That's about 2,770 lazy towers or 4,340 Burj Khalifa stacked on top of each other!

How is this possible! There is no place on the ground that can withstand this kind of pressure!

When everyone goes to school, they will be educated by teachers, saying that basic knowledge is the foundation, and if the foundation is not good, how can you build a high-rise building?

But the space elevator is a creation that does not need a foundation at all, and its lower end can even be completely suspended.

Because it's actually made from the top down!

Just like the strongest wire, it is impossible to erect it vertically upwards 10 meters high, and it will definitely fall to the east and west, and be bent by its own weight. But a 10-meter fishing line can be hung up, and even a big fish can be hoisted.

The same is true of the space elevator, which is based on the principle of a huge weight in geosynchronous orbit, which uses centrifugal force to stabilize in outer space orbit, and then hangs down a fishing line to lift objects on the ground.

The problem is that this fishing line, which can stretch for 3,600 kilometers, must be 200 times stronger than steel even if it does not hang anything, and even if it bears its own gravity! This is an almost impossible task for the current level of human technology! Not to mention, as it hangs more things, it will have to withstand several times the pulling force!

What's even worse is that the space elevator is possible because it is built from top to bottom.

But if you want to build a space elevator from the top down, you have to launch a huge amount of materials into space to build it.

It's like a chicken-and-egg or egg-and-egg question.

How can you build a space elevator without a massive amount of matter?

With that massive amount of matter, what more space elevator do you need?

Isn't this a pit daddy and an egg pain!

But at this moment, the lazy Yafei employees sitting in the elevator don't feel any pain at all.

They just have a feeling that they are comfortable.

Sitting in a seat that is more comfortable than a sofa, bearing about twice the acceleration of gravity, looking at the scenery, looking at the fading earth and the distant horizon, no one believes it, this is space travel that requires professional training to be competent.

In this world, it is estimated that only the Silence can give people such a comfortable experience of space travel.

The atmosphere inside the elevator is very relaxed, and it is clear that the builder of the elevator is very confident in the safety of the elevator.

A couple of able-bodied colleagues did not even sit in their seats, but walked around in the elevator. 2 times the gravity, it is equivalent to carrying a person with the same weight as yourself, the pressure is still evenly loaded, human legs and spine are far stronger than human beings imagined, and they can walk, but their steps are a little heavy.

When it came to the deceleration stage, the gravity on the body gradually decreased, and it was only a few minutes later when it returned to the feeling of being similar to the ground, and a voice sounded: "Di, the second floor has arrived." Passengers heading to the food court and taking the subway, please exit the elevator. If you are going up or down from this elevator, please take the downward elevator on the opposite side. ”

Many lazy Yafei employees who had already raised their feet and planned to go out took their steps back.

They looked up and saw that the light on the second floor was now on, and there was a ...... above 3456789…… Floor!

Is there a downward elevator opposite?

A group of lazy Yafei employees who were full of interest suddenly became happy, and their desire to explore suddenly swelled.

"I haven't sat in the elevator enough! If I take another downward sit, will I be weightless?" An engineer dragged his companion to the downward elevator waiting for the door on the opposite side, "Hurry up, I'm going to walk in space later, you can help me take a camera!"

"This floor is a food court, I'm not hungry, I want to go up there to see, what are the other floors, I'm really looking forward to it......"

"Take the subway, ride the subway in space, it's a joke!"

There are many more people, who are not in a hurry to get up or down, and as soon as the elevator doors open, they are attracted by the fragrance that permeates the air.

"Food court! Oh my God, what does this smell like, what does it smell like? Can you eat barbecue in space?"

In the elevator room, the upward and downward elevators are facing each other, and the doors are open. Next to the elevator room, there is a huge billboard, with the grinning space brother's face occupying half of the wall, and a huge barbecue photo with an attractive color next to it.

"When you come to space, you can eat Brother Space Barbecue!Go straight and turn left!201 booth!
