Start a Subspace

At nine o'clock in the morning, the development meeting on the sun wreckage was officially held in the government conference room!

With such a big event, Zhang Ran naturally sat on the rostrum.

And the speaker of the new government, Zhou Chengfeng, sits to his left. The audience is full of experts and scholars from all walks of life.

The development of sun debris is related to the future of mankind, and it is also a systematic project.

"Ladies and gentlemen, good morning, everyone. In our meeting this time, we must discuss clearly the difficulties and risks of developing the sun wreckage."

No nonsense, Zhang Ran said straight to the point: "In the last month, we will reach the edge of the sun wreckage, that is, the valley of waves. It is always right to think about it first."

"For this work, we have been preparing for a long time, and major laboratories have also worked hard for more than a year. Are there any difficulties that are insurmountable in principle?"

A slight discussion sounded in the conference room.

Soon, Professor Fan Tianyu from the Ark Laboratory spoke: "Let's put it this way, the sun debris is actually very thin, but it is a little better than the vacuum... There are not many theoretical difficulties, after all, it is only in space. It captures thin matter in the medium and collects charged particles with a strong magnetic field."

"But there are many difficulties at the practical application level."

"The first is the line of sight problem. Without the sun, our current observation ability has been greatly weakened."

"The strongest light we emit cannot be compared with the sun."

"If we use a more vivid metaphor, we are like a paramecia, slowly crawling into our hall, but the hall is not turned on, it is dark. So the paramecia can only turn on its own light and illuminate it. Illuminated the surrounding 1 micron space."

"That's almost what it means..."

"Because the material in the wave valley is relatively dense, if a high-speed meteorite with a diameter of 1 centimeter hits the spacecraft collecting the material, its power is no less than that of a cannonball."

"If a 10-centimeter meteorite hits a spaceship, it's no different from a high-explosive bomb. This is the first big risk that comes from the decline in observation ability. Our spaceship is easily destroyed."

"Is there a solution?" Zhang Ran asked.

Professor Fan shrugged his shoulders: "Of course...more powerful energy, stronger magnetic field, brighter light, expanding our horizons. Vigorously creating miracles, that's for sure."

Lin Qiuyue sat in the middle of the first row, nodded slightly, and did not speak.

There is a reason why she sits in the first row, because the nuclear fusion project of the Oriental Laboratory has progressed very quickly this year!

It has been discharged stably for 2000 seconds.

And this duration increases almost exponentially, doubling about every two months.

This rapid progress can be said to be another kind of Moore's Law.

According to the current progress, one year later, after a stable discharge of 128,000 seconds, it is almost possible to walk out of the laboratory and build a demonstration reactor.

She is quite confident about this.

Prof. Fan continued: "The second difficulty, the capture of thin matter in space, requires the use of materials with strong magnetic fields."

"But it is meaningless to capture sails that are too small. One square, two squares, can't capture too much material. At least one capture sail with an area of ​​one square kilometer is needed to capture enough space material, so that we can get back to our original cost as soon as possible. ."

"The sail can be very thin, as long as a layer of thin film material is sufficient."

"There is a large amount of helium-3 in the nebula material, which is the main fuel for the next generation of nuclear fusion."

"The third difficulty, the big spaceship! We need a bigger spaceship as the main base of the real universe."

"The current Ark, the performance is not enough to meet the demand... At least a 10 times larger spaceship."

Zhang Ran understood what the other party meant, and called for the money!

Technically, there seems to be no problem, but lack of money is the biggest problem.

He scratched his hair, trying to use my creative energy, what a headache!

There is only 1450 creation energy!

As for the next era... it can only be pinned on the early completion of nuclear fusion.

Since the completion of the government reform, in principle, Zhang Ran's creation ability is no longer used for people's livelihood, but only for military and scientific research.

At present, he is only willing to invest in high-end raw materials, because raw materials are cheap to invest and cost-effective. For example, a high-purity wafer, a wafer with 1 point of creation energy, can produce hundreds of thousands of high-end chips, which is very cost-effective.

Or high-precision instruments that humans cannot currently manufacture, such as various devices in large tokamak.

Now, with the recovery of industry, the technological products that humans can make by themselves are slowly increasing. Since human beings can produce by themselves, why should I invest in it and directly make a spaceship? Beautiful as you think!

Thinking about it, he felt a little bit of liver pain again.

Forget it, be generous, it's not easy for everyone, 50, at most 50 of the creation energy!

No more will do. With the advancement of technology in the future, this thing will become more and more valuable.

The creation ability of the warp is proportional to the level of civilization.

If placed in ancient times, 1 point of creation energy may only produce 1 ton of steel; now it can produce 100 million tons of steel, which is the qualitative change caused by the change of civilization level.

When nuclear fusion comes out, it will definitely be regarded as a great breakthrough. Maybe there will be qualitative changes?

So ~www.wuxiahere.com~ It's not that Zhang Ran is stingy, but that he really wants to leave energy for the future.

The time in the future is long, and now it is wasted. What if there is a crisis in the future?

……

After Professor Fan finished his speech, everyone began to publish some technical details, including what superconducting magnets, what critical temperature, critical magnetic field, and critical current density. As long as it's not too professional terminology, it can be barely understood.

In the end, everyone still believes that magnets made of graphene are cheap and efficient, and are the best material for material capture sails.

Every time the material capture sail is turned on, it can attract charged particles in a radius of 5 kilometers, and can capture 600 grams of material in about an hour.

600 grams per hour?

Zhang Ran really didn't know what to say. There was only so much to say...

However, it is so difficult to salvage the sun wreckage, and the capture sail can be used for a long time. As long as the cost can be recovered, it is not a big problem.

After that, Professor Huo Dong, who specializes in high-dimensional universe research, said in a slightly hoarse voice: "Everyone, please be quiet, we will not only discuss technical difficulties, but also discuss possible dangers!"

"The accumulation of sun debris is caused by a space folding phenomenon called 'wave valley'."

"In areas close to space fragmentation, the curvature of space is more complex, unlike normal space, which is smooth."

"There may be natural gravitational forces in some places, just like waves, with high curvature in the middle and low curvature on both sides, so 2.3 Earth masses of matter are retained at the 'valley bottom'."

"Due to the wave valley phenomenon, the space in this area is extremely fragile, and vacuum decay will erupt at any time, and the entire area will fall into high-dimensional space."
