as soon as Ye Su returned to Los Angeles, he went into the experiment and continued his research work.

The research he is going to carry out this time is not about mecha, but on other fields.

Although mecha is a measure of the degree of civilization and development, it is also very important for human beings, but now is not the time to study mecha technology.

Although Yesu also wanted to work out a real mecha, rather than the current reduced version of the humanoid armor.

But now the technical conditions can not meet the requirements, the real mecha is still too far away for Ye Su.

Because the real mecha involves too many technologies, most of the present human beings can not do it, even Ye Su can't do anything, and can only wait for the development of human technology.

So Yesu is going to study something else, something that is also very important to human beings.

"Rem, help me make a list of the things I've sorted out before, and I'll see what other technologies are not finished."

Yesu stood in front of the experimental platform and said to REM in mid air.

"Yes, master." REM answered cleverly.

Soon there was a light curtain in front of Ye Su. On the light curtain was a complete science and technology tree with many different technical projects arranged on it.

From the results of this technology tree, we can see that this is the technology tree of a large project.

At the top is a model of a large spaceship, which is the ultimate goal of this technology tree.

This is a science and technology tree about spaceships, which has all the specific technology projects with spaceships.

This science and technology tree about spaceship was created by Ye Su a while ago.

Since the mecha can't be made yet, it's better to study the spaceship.

The technology tree lists the specific technologies needed by spaceships. If all the above technologies are developed, Yesu can make the spaceship she wants.

There are many bright technologies on this technology tree, which means that this technology has been developed.

But some technologies are bleak, and they are still in the state of completion.

Judging from the situation on this technology tree, many technologies related to spaceships have been conquered. Most of the technology names are on, and there are not many names left.

Many of the technologies on the science and technology tree are developed by Ye Su's R & D team.

In particular, most of the branch technology is the result of Ye Su's technical staff.

From the name on the technology tree, you can see how much credit the team has made.

There are countless technologies needed for spaceships, and now they have completed most of them.

Of course, what they have accomplished is only some less difficult technologies, and the most difficult core technologies are all solved by Ye Su himself.

For example, several nodes in the biggest core of the technology tree are all written by Ye Su.

The gravity control technology developed by Ye Su some time ago occupies a very important position in the science and technology tree. It is a core technology that can not be bypassed.

Now the name of gravity control technology has been lit up, which is the irreplaceable role of Yesu.

How many years will it take for humans to build spaceships without yezou to conquer the most difficult core technologies.

Now most of the technology of the whole technology tree has been lit up, only a few core technologies are left, and the whole technology tree is completely completed.

That is to say, the technology of spaceship is very mature now. As long as Ye Su completes the final several core technologies, he can start to manufacture spaceships.

It is because of this that Ye Su studied this technology tree, and now he is ready to complete the last few core technologies.

When all the technology has been completed, the spaceship will really be able to achieve.

This is Yesu's dream, the ultimate goal of his space program.

If we have a spaceship, we can travel in space, and the efficiency is much higher than rocket.

Ye Su is holding her chin in her hand, looking at the technology tree in front of her and thinking about something.

"Let me see which technology is better to study first. The remaining core technologies are very troublesome and can't be solved in a day or two."

It turned out that Yesu was trying to figure out which technology to study first, so he asked REM to list the entire science and technology tree about spaceships.

"Let's solve the problem of curvature engine first. Although this technology is the most difficult, it will be solved sooner or later."

"This is the most important thing about spaceships. Spaceships without curvature engines are a joke."After thinking about it for a while, Ye Su finally determined the next research project, and was ready to start to attack the technology of curvature engine.

This technology is essential to the universe, because curvature engines can actually fly faster than light.

The universe is so huge that it takes a lot of time to fly at the speed of light.

If the spaceship can't exceed the speed of light, it will lose its practical significance.

It's better to fly in the solar system. If you want to fly across the solar system, even if the speed reaches the speed of light, it will take too long.

So if you want to really travel in space, surpassing the speed of light is a problem we have to face.

A real spaceship must at least reach several times the speed of light.

Otherwise, the time spent in space travel would have to be counted in a hundred years.

But it is very difficult to make the universe exceed the speed of light very much.

According to the principle of relativity, no object can move beyond the speed of light, which is the most basic inference of relativity.

The faster an object is, the greater the ability it needs to accelerate. This is the fundamental principle of relativity.

If you want to accelerate the spacecraft to the speed of light directly, the energy required is infinite, which is why objects can't exceed the speed of light.

Therefore, spacecraft can not achieve the goal of exceeding the speed of light by means of direct acceleration.
