Chapter 592

But now? Aliens came to the door to communicate, and humans greeted them at the door of their home!

This is the change of the times, the change of human vision and strength

Just as they were imagining the future, a prompt sound suddenly sounded in their ears, "Dear citizens of new human civilization, Mr. Zhang Yuan, Hello, the standard room in XingKong port you booked has entered the queue sequence, and there are 132 rooms left to choose."

The sound surprised Zhang Yuan. This is because there are many tourists in the port and the rooms are limited. It usually takes several months to queue up.

If they don't line up, they have to return to the surface to live.

Unexpectedly, it was booked on the last day of the holiday, which gave them a little surprise.

"We can sleep here today! What room do you want to sleep in, low gravity, no gravity, or normal gravity? "

Lin Xuanxuan thought, "of course it's normal gravity! What do you sleep without gravity, frightened, always having nightmares... "

Zhang Yuan stared at the screen for a long time and suddenly said, "it's really not emotional! I also want to sleep in a "golden section than gravity" room. There's just the last one. "

"Golden section?"

"It is said that in this gravity environment, people's blood circulation is very smooth and their body will be very light. Young boys and girls like it very much, ha ha... It's hard to book such a room."

Lin Xuanxuan rolled her eyes and wondered what the so-called "golden section than gravity environment" was

A beautiful night will soon pass

The next day, everyone started normal work.

At six o'clock in the morning, a large group of people had been waiting at the observatory. Until nine o'clock in the morning, people finally found the trace of the curvature spacecraft of the TOS civilization. It was a very large spacecraft, which was expected to carry about 1 million people and sail at the speed of 0.1C.

If it weren't for the strong light emitted by the ship, ordinary radar would really be unable to lock the ship.

"Conventional radar must be updated! Such a big ship still can't be locked. What can we do if we fight in the future? " Several generals were there and were very dissatisfied with the current military equipment.

Until about six million kilometers near the star harbor, the spacecraft suddenly stopped, as if there was no deceleration process.

Yes, curvature sailing is such a magical way of sailing.

Of course, the use of curvature navigation also has limitations. The curvature engine has strict requirements for space curvature, and there is no way to navigate in a place with great gravity, otherwise it may cause a certain amount of damage to the engine itself. At least, the engine will explode directly, or at least produce a super strong traction wave, which will tear the whole spacecraft directly!

Therefore, in order not to lose mobility, the spacecraft still needs to be equipped with conventional navigation means.

With a slight vibration, the large carrier of the TOS civilization docked with the star port, and the bright indicator light came on.

"Welcome, welcome dear friends!" Ms. captain took the lead in sending out condolences.

People cheered loudly, cheered the arrival of these old friends, and prepared a quite good ecological environment for them.

The reason why the TOS civilization is willing to take the initiative to come here also brings such a large number of people. On the one hand, it is for scientific and technological exchanges, such as some experience exchange in science and technology, telling about past friendship, cultural exchanges, military exchanges and so on.

On the other hand, it is mainly to seek optical perception.

Yes, optical perception!

Without optical perception, the science and technology tree of TOS civilization is too deformed. There is competition among the four civilizations. TOS people must make up for this defect in order to develop better.

As an expert in additional perception, Zhang Yuan naturally has a high status and stands at the forefront of the welcoming team.

Soon, the heads of the two sides contacted each other, offered condolences to each other, and talked about their historical origins, historical friendship, etc. it sounded quite boring. It's really boring and a necessary process.

Then we began to arrange non-governmental exchanges and scientists' meetings.

Among the 100 million people of mankind, more than 60 million are the new generation. This is the first time they have seen this alien civilization closely related to mankind.

The combination of large giant salamanders and wolf dogs is very interesting. These dogs are also wearing power armor. When they see so many humans, they are curious to die and bark.

According to the idea of many young people, the other party just came here with a million people. It is really only when the relationship is good to a certain extent.

Since the relationship between the governments is good, there will be no problems among the people.

It is definitely a very profound friendship to jointly break through level 4 civilization. How many level 3 civilizations in the galaxy can become level 4 civilization?

Only some elderly people can realize the small contradictions that have occurred. Is that a contradiction? In front of the final results, there is absolutely no contradiction!

Soon, many small spacecraft began to compete in speed. Coupled with the space weapons tour, some military fans were very happy.

It is very interesting to observe these sub light speed spacecraft from the surface. You will find that their shapes are pulled into "long noodles". Whose noodles are longer means who flies faster.

In fact, it is not the deformation of the spacecraft, nor the relativistic effect, but the observation disorder of the spacecraft's image due to too fast speed.

As for the military level, the battle at the speed of sub light is also different from the conventional military war. For example, the ultra-high-speed curvature missile has become a big killer, and how to make a big turn in the curvature navigation has become a super problem.

The two sides can jointly study new contents in this regard, compete and exercise with each other, and one competitor must develop much faster than alone.

"... Hello, new human friends. As for the difficulties in curvature technology, there are still many. The first level is about a series of problems brought about by breaking through the speed of light, referred to as light barrier. "

"First of all, after breaking through the light barrier, our spacecraft is faster than photons. How should we communicate with each other? Whether it's conventional flight or cellular linkage between military spacecraft, communication is crucial! "

"In addition, after breaking through the light barrier, it will also bring significant confusion to the observation picture. The faster the speed, the faster the picture confusion. It must be unsafe to fly around with your eyes closed... We must find the right algorithm... "

Standing on the stage was tocalia Antongding, a great scientist of TOS civilization. What he said was not complicated, and almost everyone could understand it. This is also a part of mutual communication.

After a spaceship catches up with its own photons, it will produce all kinds of strange phenomena.

If you look directly in front of the spacecraft, you will find that it... Is "retreating"!

If you look directly behind the spacecraft, you will find that the image caused by it is still the speed of light, and there is no "super speed of light"!

If you look at it from the side of the spacecraft, it will be even more strange. It becomes a ramen shape. Then this Ramen is disconnected from the middle and divided into two spacecraft flying in the opposite direction. Of course, these ships are just images.

In short, these strange situations will become difficulties in communication.
