Having said that, there is a bit of a risk for Future to stay here for observation, but the distance of 2 light years can already basically dilute the traces of Future Future, and the danger can be controlled.

"Even gravitational-wave telescopes are unlikely to be able to detect objects that are only 10 billion tons of mass 2 light-years away......"

"Future will also remain in radio silence for long periods of time, maintaining its own concealment."

At the same time, many factories are also producing related stealth materials. Although the ship already had a strong stealth function when it was first designed, it is not a bad thing to temporarily strengthen it now.

In less than half a month, Future has arrived at the established area, gradually stopping its movement, and various robots are busy back and forth on the surface.

"The radio interferometer is fully activated."

"And ...... In addition, high-power experiments and high-power industries were temporarily suspended. Yu Yifeng gave a few orders again.

Witnessing the quiet starry sky, he sighed softly.

All plans have been implemented, and the new humans have done everything they can. The next thing can only depend on the destiny of heaven......

The long wait began......

On the one hand, people hope that the other party will appear later, preferably twenty or thirty years later, so that the probability of the planetary warship escaping will be greater.

On the other hand, this kind of waiting is really too painful......

Waiting in "years" is not a day or two, how can you not be in a hurry? This is definitely a test of patience at the top of the government as well as ordinary people.

With this ambivalence in mind, many of the citizens of the new humanity had no intention of working at first, often running to the observatory to see if any enemies had appeared. There are also those who are worried about the staff who go to the metal planet, where they have their relatives and friends......

More than 30,000 people, which is almost 0.5% of the population of the new human race.

However, man is a very adaptable creature, and as time passes, no matter how much he worries, all of them turn into calm. As long as the enemy does not appear, the "Pangu" will definitely be safe, and it is useless to worry, and the whole society has once again entered the stage of normalized work

At this stage, in order to maintain radio silence and not to emit too much heat, all the big experiments and the big factories have stopped.

However, another big project is in full swing inside Noah, and that is the design of the planetary spacecraft!

It's just design, and it doesn't use much energy.

A metal spaceship, equivalent to a large ball with a diameter of 2,000 kilometers, can be used as long as it can be dug up.

These spaces are much larger than the Noah, and how to make better use of them is a top priority.

Architects are working on related material reinforcement techniques, as well as the mechanics of the planet as a whole.

Various military scientists and nuclear physicists are also discussing what kind of weapons should be installed on the entire planet and how to maximize combat effectiveness.

The most important of these is, of course, new materials. Whether it is the reinforcement of the planet or the weapon system, all of them are inseparable from the support of new materials.

For now, cutting-edge materials science is a frictionless, zero-viscous material. This material is the fifth state of matter, the Bose-Einstein condensate. Researchers use a series of technical means to fuse light and matter, and a series of very strange properties will appear, such as light stasis, superfluidity, and so on.

However, it is still unknown how to apply the "Bose-Einstein condensate" to large-scale industry. Now it can only be used in virtual imaging, solar cells, lasers and other industries, which always feels a bit overkill.

The next step is the study of "metallic hydrogen" and "metallic nitrogen". The research in these two aspects is relatively mature. The energy storage capacity of these chemicals is limited to nuclear fission, and it is very good to use to make chemical batteries, and they also have very magical properties.

Metallic hydrogen needs to be pressed at a pressure of five million atmospheres, and as a metastable substance, the material itself is not in equilibrium, but it can remain relatively stable.

In other words, when the huge pressure is removed, the metallic hydrogen will not immediately explode into ordinary hydrogen, but temporarily become a superconducting material at room temperature and pressure, just like a piece of glittering metal. It's like a piece of dry ice, volatile all the time.

It's a very amazing property, and if you can keep the metallic hydrogen for a little longer, and the evaporation rate is slower, so that it can release energy gently, it is equivalent to a very, very efficient battery.

Although its energy density is not as high as that of nuclear fission and nuclear fusion, it can be made very small and can store more electricity than traditional aluminum-air batteries. For now, it's still very much used.

Metallic hydrogen can also be used to make a "magnetic cage" to confine the plasma, and "contain" the hot ionized gas, which can be said to be the latest version of controlled nuclear fusion.

Of course, crazy scientists have long stopped caring about "nuclear fusion", which has already been realized, and they plan to complete a quark energy research experiment at the core of the metal planet!

Metallic hydrogen is a necessary experimental material.

At ultra-high temperatures of 1 trillion degrees Celsius, protons and neutrons will completely melt and become plasma composed of quarks and gluons. This pot of "quark soup", under certain conditions, can be converted into quality and energy. Heavier quarks quickly turn into upper or lower quarks through a process called particle decay. Particle decay is a process of changing from a high-quality state to a low-mass state.

In ordinary nuclear fusion, the mass-energy conversion efficiency is about 3% and 7%. With the conversion of the quark level, it can convert about 40% of the mass, which can be said to be an order of magnitude increase!

"Ordinary nuclear fusion is enough, right...... The materials for nuclear fusion are almost endless. This kind of quark can ......" When Yu Yifeng saw this experimental plan, he was a little speechless. Has this group of researchers been bored to this extent?

Generally speaking, nuclear fusion is already sufficient to meet the needs of new humans, whether it is to propel the planet or other industrial activities, and produce enough energy.

Now it's time to make a quark energy that is extremely difficult...... No matter from which point of view, trillions of degrees of heat, and millions of atmospheric pressures, it is many times more difficult than nuclear fusion.

And the energy that can be increased is only an order of magnitude. The use is still a mass-energy conversion, and there is no essential change.

"The conditions under which quark chowder is formed are very close to the state of the universe a few microseconds after the Big Bang. What we are looking for is not only new energy, but also small irregularities. This experiment is beneficial to our understanding of the high-dimensional universe......" Professor Ding said unhurriedly, while pulling out a series of professor autographs from his pocket.

"And if you want to make antimatter in bulk, you have to start at the quark level...... Lots of antimatter! He whispered.

"Antimatter? Okay......" Yu Yifeng's heart moved, and he shrugged his nose slightly.

If you want to synthesize antimatter in batches, it is better to start at the quark level, after all, all elementary particles come from a vacuum. A meson is made up of quarks and antiquarks. The Big Bang also produced almost equal amounts of matter and antimatter.

"How to manipulate mesons, leptons, and baryons is equivalent to manipulating strong interactions, right? Do you want to use vacuum energy? ”

Faced with such a petition, Yu Yifeng thought about it and agreed. He has never objected to this kind of scientific research activities. And he doesn't think that scientists can find anything useful, they are at most just curious.

Besides, the "Pangu" Battlestar is still in the process of escaping, and all the current designs can only be in the theoretical stage.

After receiving the reply, Professor Ding Yidong left satisfied.

Next, Gaia Creature Ling also put forward her own request: she hopes to add a super-large ocean to the surface of the planet! u
