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!

For such a big matter, Zhang Ran naturally sat on the rostrum.

The chairman of the new government, Zhou Chengfeng, sat on his left. The next stage is 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 sun debris.

There is no nonsense, Zhang Ran said straight to the point: There is still the last month, we will reach the edge of the sun wreck, that is, the wave valley area, it is always right to think about it first.

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

There was a slight discussion in the conference room.

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

However, there are many difficulties at the practical application level.

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

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

If we use a more vivid metaphor, we are like a paramecium, slowly crawling into our hall, but the hall is dark without lights. So the paramecium can only turn on its own light, illuminate Brightens the surrounding 1-micron space.

That's pretty much what it means...

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

If a 10-centimeter meteorite hits the spacecraft, it is no different from a high-explosive bomb attack. This is the first big risk brought about by the decline in observation capabilities. Our spacecraft 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, and expand our field of vision. Miracles can happen with great effort, that's for sure.

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

The reason why she sat in the first row was naturally for a reason, because the nuclear fusion project of Dongfang Laboratory was progressing very fast this year!

At present, it has been stably discharged for 2000 seconds.

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

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

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

She's pretty confident about that.

Professor Fan continued: The second difficulty is the capture of space-rare matter, which requires materials with strong magnetic fields.

But a capture sail that is too small is meaningless. An area of ​​one or two square meters cannot capture too much material. At least a capture sail with an area of ​​one square kilometer is needed to capture enough space material, so that we can return to our original cost as soon as possible. .”

The sail can be very thin, with just one layer of membrane material.

There is a large amount of helium-3 in the nebular 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 performance of the current Ark is not enough to meet the demand...at least a large spacecraft that is 10 times larger.

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

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

He scratched his hair, wanting to use my creation energy, a headache!

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.

He is currently 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 tokamaks.

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

Thinking about it, he felt a faint pain in his liver again.

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

It won't work any more. With the advancement of technology in the future, this thing will become more and more valuable.

The creation ability of the subspace is directly proportional to the level of civilization.

If placed in ancient times, 1 point of creation energy might only be able to produce 1 ton of steel; but 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 a qualitative change?

So, it's not that Zhang Ran is stingy, but that he really wants to save energy for the future.

The future is long, and now it is squandered, what should we do if a crisis occurs in the future?

...

After Professor Fan finished speaking, everyone began to publish some technical details, including superconducting magnets, critical temperature, critical magnetic field, and critical current density. As long as it is not too professional terminology, it can still be understood.

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

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

600 grams an hour?

Zhang Ran really didn't know what to say, there were only so many people with such a big fanfare...

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

After that, Professor Huo Dong, who is in charge of the study of high-dimensional universe, said in a slightly hoarse voice: Everyone, please be quiet, we not only want to discuss technical difficulties, but also discuss possible dangers!

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

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

In some places there, there may be a natural gravitational force, just like a wave, with a high curvature in the middle and low curvature on both sides, so 2.3 Earth's masses of material 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.
