Chapter 583

But now? The aliens came to the door to communicate with each other, and the human beings welcomed them at their own door!

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

Just as they were thinking about the future, a prompt sound suddenly sounded in their ears, "dear new human civilization citizen, Mr. Zhang Yuan, Hello, the standard rooms of star port you have reserved have entered the queue, and there are 132 rooms left to choose."

Zhang Yuan was pleasantly surprised by the sound because of the large number of tourists and limited rooms in the port, which usually takes several months to queue up.

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

I didn't expect to book it on the last day of the holiday, which gave them a little surprise.

"We can sleep here today! What kind of room would you like to sleep in, low gravity, no gravity or normal gravity? "

Lin Xuanxuan thought, "of course, normal gravity! What kind of weightless sleep? I'm scared. I always have nightmares... "

After staring at the screen for a long time, Zhang Yuan suddenly said, "it's so emotional! I also want to sleep in a room with a "golden section environment" and just have 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 get a room like this. "

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

A good night will soon pass

The next day, everyone began to work normally.

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

If it wasn't for the strong light from this ship, ordinary radar would not be able to lock this ship.

"Conventional radar must be upgraded! There is still no way to lock such a large spaceship. What can we do if we fight in the future? " Several generals were there, 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 on the curvature of space, and there is no way to navigate in the place of great gravity. Otherwise, it may cause a certain amount of damage to the engine itself. The engine may explode directly, or it may produce a super strong traction wave, which will tear the whole spacecraft directly!

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

With a slight shock, the large-scale Mothership of TOS civilization docked with the star harbor, and the bright indicator light was on.

"Welcome, welcome dear friends!" The captain took the lead in offering her sympathy.

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

The reason why the tosian civilization is willing to take the initiative to come here is that it has brought such a large number of people. On the one hand, it is for the exchange of science and technology, such as the exchange of some experience in science and technology, the sharing of friendship, cultural exchanges, military exchanges and so on.

On the other hand, it is mainly for 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 extra perception, Zhang Yuan naturally has a high status and stands in the front of the welcoming team.

Soon, the heads of state of the two sides contacted each other, exchanged sympathy, and told each other their historical origins, historical friendship and so on, which sounded rather boring. It's really boring. It's a necessary process.

And then we started to arrange people to people exchanges and scientists' meetings.

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

The combination of giant salamander and wolf dog is very interesting. These dogs are also wearing power armor. When they see so many people, they are curious to die and "whine whine".

According to the idea of many young people, the other party just comes here with a million people. It's true that the relationship is good to a certain extent.

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

It is definitely a very profound friendship to break through the fourth level civilization together. How many third level civilizations in the galaxy can become the fourth level civilizations?

Only some old people can understand the minor contradictions that have ever occurred. Is that a contradiction? In front of the final results, there is absolutely no contradiction!Soon, a lot of small spaceships began to compete in speed, coupled with the space weapons exhibition, which made some military fans enjoy themselves.

It's very interesting to observe these subluminal spaceships from the surface, and 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 spaceship or the relativistic effect, but the observation disorder of the spaceship image due to the high speed.

As for the military level, sub light speed combat is also different from conventional military warfare. For example, the super-high speed curvature missile has become a killer, and how to make a sharp turn in curvature navigation has become a super difficult problem.

The two sides can jointly study new contents in this area and compete and exercise with each other. One competitor will certainly develop much faster than the other.

“…… Hello, new human friends. As for the difficulties in science and technology, there are many more. The first is about a series of problems brought about by breaking through the speed of light

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

"In addition, after breaking through the light barrier, there will be a large amount of confusion in the observation picture. The faster the speed is, the faster the chaos is. It's not safe to fly around with your eyes closed We have to find the right algorithm... "

Standing on the stage to speak is tokalia Antongding, a great scientist of the tosian civilization. What he said is not complicated, and almost everyone can understand it. It's also a part of communication.

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

If you look right in front of the ship, you'll find it Back off!

If you observe from the rear of the spaceship, you will find that the image it creates is still the speed of light, there is no "super speed of light"!

If you look from the side of the spaceship, it's even more strange. It's like a ramen. Then this Ramen is broken from the middle and divided into two spaceships flying in the opposite direction. Of course, these ships are just images.

All in all, these strange situations will become difficulties in communication.
