When I woke up again, I don't know how long it had been, and when I opened my eyes, the black bear was cleaning up the used syringe.

"Where is this?" Hu Bin usually doesn't sleep well, it's rare to sleep so deadly that he didn't even notice the black bear when he came to his side.

"We've arrived at the place, and the boss is waiting for you on the bridge." The black bear opened a fist-sized hole in the bulkhead and threw the syringe into it.

That hole is the ship's garbage disposal terminal.

Hearing this, Hu Bin hurriedly rubbed his face: "It's here so soon?" Come on! He rushed out the door, not bothering to wash his face.

"Hey, don't be in such a hurry!" The black bear hurriedly followed, and as soon as he went out, he found that Hu Bin was standing outside the door in a daze.

"What's wrong?" The black bear asked curiously.

I was quite rushed just now, how can I go out like a different person? Looking left and right, there was no one, and it was impossible for a few beautiful women on the ship to come to the men's dormitory.

Hu Bin touched his nose embarrassedly: "That, which way is the bridge going?" ”

"Damn, I'm really convinced." The black bear had a failed expression on his face, "Go this way, just two streets away." ”

The passages in the battleship extend in all directions, not to mention that the battleship is only more than ten kilometers long, and the various passages in the ship add up to nearly 600 kilometers, which is more complicated than the rat holes dug by mentally disordered rats, comparable to a maze. The wide one can run four battery cars at the same time, and the narrow one can only allow two people to pass by. The crews used to call the wide passages streets, the narrower ones alleys, and the narrowest ones holes.

Bored crew members will name familiar passages to their liking, such as the passage near the bridge called Fugui Lane, which has nothing to do with money and implies that most people do not have the right to enter the bridge. And the official name should be the thirty-four-thirty-sixth deck core area.

It is so called because the spherical panoramic display system and control system of the bridge are added together to penetrate three decks.

It is said that there is a narrow road in the garbage disposal area called the scum hole, and I don't know which bear child named the road, so it was called.

The black bear said as he walked: "I'll prepare a case for you when I turn around, so that you don't have to send someone to find you if you get lost." ”

Normally, the officers and men on the ship only operate in areas they are familiar with, and once they enter an unfamiliar environment, they must use personal terminals to receive navigation from the ship's control system, so as not to get lost.

"That's a good feeling, and it saves me from always sending people to follow me, making me feel like I'm mentally retarded." Hu Bin had just arrived at the Yangtze River, and the information of his personal terminal had not yet been filed in the information center, so he could not use the navigation function.

As he walked, the black bear suddenly slapped his forehead: "Hey, Expert Hu, can I ask you something?" ”

"Ask, I know for sure." Hu Bin was a little apprehensive, he kept calling him Staff Officer Hu, why did he suddenly change his name to Expert Hu?

"That's the case, many brothers can't figure it out, this speed of light is so fast, what if it hits a stone?" The black bear asked solemnly.

"Huh?" Hu Bin's jaw almost dislocated and hit a stone? It's a collision with a small celestial body!

"Don't you know what to do?" The black bear's disappointment was overflowing, "Can't you study it?" Everyone's hearts are hanging, usually flying, touching a stone or something, the outer armor hard top will pass, but the speed of light hitting the stone, isn't it like a comet hitting the earth? Besides, the universe is so big, what the eye sees is not necessarily in the original place, and hitting a stone is still a trivial matter, if you hit a planet headlong, or even crash into the sun, then there is no place to cry. ”

"No, no, no." Hu Bin hurriedly explained, "I really know about this. ”

"Really? That's great! The black bear was overjoyed and urged repeatedly, "Speak quickly." ”

Hu Bin carefully recalled the information he read not long ago: "I don't understand this very well, but it probably means that space has a self-healing balance, and the speed of light breaks the balance of space...... Hey, let's put it this way, the faster-than-light engine can directly bring the spacecraft into faster-than-light, and there is no need to slowly accelerate to sub-light speed before breaking through, so until now, no one knows whether there is a light barrier in the road, but after entering the faster-than-light speed, a special physical phenomenon has been discovered, and a special protective layer will be formed directly in front of the spaceship...... Well, what's that, the sound impediment, right? When an airplane breaks the sound barrier, a cone-shaped single cone is generated at the front end, called a sonic boom, which will operate the ground building if the plane flies at supersonic speeds at low altitudes......"

The black bear suddenly realized: "I understand, you mean that when the speed of light is faster, there is also a 'light explosion' in front of the battleship, right?" Even if there are rocks, they will be hit by light and explosion, and they will not hit the spaceship, right? ”

That's what it means, not to mention small celestial bodies, even smaller dwarf planets may not be able to withstand the impact of the Yangtze River's light explosion. So just make sure that there are no stars or planets in the path before starting the faster-than-light engine. Hu Bin breathed a sigh of relief, and wanted to explain the professional theoretical knowledge in simple terms, it is really not an easy task, no wonder teachers are not easy to do, and excellent teachers are even rarer.

In fact, of course, it is not as simple as Hu Bin explained, the so-called light explosion involves profound physics knowledge such as space curvature, not to mention Hu Bin, a half-understood half-hanger, even if he is a physicist with a deep understanding, he may not be able to explain it clearly in a few sentences.

Fortunately, the calculation of the route of superluminal flight is all handed over to the ship's computer, and the relevant data are all within the scope of consideration, and there is no interference from the outside world at all.

However, it seems that those who have this kind of thinking are by no means alone, after returning to Yanjing, do you suggest to Lu Jian to popularize the knowledge of faster-than-light flight in the whole army?

Hu Bin had endless thoughts in his mind, but his footsteps did not stop, and he followed the satisfied black bear into the bridge.

Ye Fei was standing in the bridge with his hands behind his back, and when he heard the sound of the airtight door opening, he naturally turned around and said hello: "Staff Officer Hu, did you sleep well?" ”

Hu Bin didn't expect Ye Fei to say this in the first sentence, so he was stunned for a moment and immediately replied: "I slept very well, Xie Lu Xie...... This is a double star? ”

There was a fist-sized bright spot on the left and right sides of the panoramic screen, and Hu Bin stared at the screen with both eyes without blinking, eager to pounce directly into it.

"Probably so." Ye Fei smiled slightly, "The data we have measured, the one on the left is Centauri αA, the one on the right is B, the current distance of the binary star is 21.4 astronomical units, A has three planets, B has two, and there is a gas giant on their Lagrang day point, which is really amazing." ”

The Lagrang point is simply the point where the gravitational pull of the AB binary stars cancels each other out, and is actually still affected by the gravitational pull of the binary star, but the gravitational force is balanced here, like the fulcrum of a lever.

Out of personal habit, I like to explain the cosmic environment as clearly as possible, and if you have any suggestions, please let them know in the book review area.
