Beneath Deep Space

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

"Even with a gravitational wave telescope, it is difficult to detect an object with a mass of only tens of billions of tons two light years away..."

"The Future will also be in a state of radio silence for a long time to maintain its concealment."

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

In less than half a month, the Future has arrived at the designated area and gradually stopped moving. Various robots are busy back and forth on the surface.

"The radio interferometer is fully operational."

"There are...other high-power experiments and high-power industries temporarily suspended." Yu Yifeng issued a few orders again.

Seeing the quiet starry sky, he sighed softly.

All plans have been implemented, and the new humans have done everything they can to do their best. What happens next can only depend on fate...

The long wait begins...

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 battleship escaping will be greater.

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

Waiting in "years" is not just a day or two, so how can you not be impatient? This will definitely test the patience of senior government officials and ordinary people.

With this conflicting mood, many new human citizens were unwilling to work at first and often went to the observatory to see if any enemies appeared. There are also some people who are worried about the staff going to the metal planet, where they have their relatives and friends...

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

However, humans are highly adaptable creatures. As time goes by, no matter how worried you are, everything turns into peace. As long as the enemy does not appear, the "Pangu" will definitely be safe, and there is no point in worrying. The entire society has once again entered a normal working stage.

At this stage, in order to maintain radio silence and not emit too much heat, all large-scale experiments and large factories have been stopped.

But another major project is in full swing inside Noah, and that is the design work on the planetary spacecraft!

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

A metal spaceship is equivalent to a large ball with a diameter of two thousand kilometers. Many spaces inside can be used as long as it can be dug out.

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

Architects are studying related material reinforcement techniques and the mechanical structure of the entire planet.

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 them is, of course, new materials. Whether it is the reinforcement of the planet or the weapon system, everything is inseparable from the support of new materials.

For now, the most cutting-edge material science is a frictionless, zero-viscosity material. This material is the fifth state of matter, a "Bose-Einstein condensate." Researchers use a series of technical means to fuse light and matter. At this time, a series of very weird properties will appear, such as light stagnation, superfluidity, and so on.

However, how to apply "Bose-Einstein condensate" to large industry is still unknown. For the time being, it can only be used in industries such as virtual imaging, solar cells, and lasers. It always feels like it is overkill.

Next is the study of "metallic hydrogen" and "metallic nitrogen". Research in these two aspects is already relatively mature. The energy storage capabilities of these chemical substances are limited to nuclear fission. They are very good for making chemical batteries, and they also have very magical properties.

Metallic hydrogen needs to be pressed under a pressure of five million atmospheres. As a metastable substance, the material itself is not in equilibrium, but it can maintain relative stability.

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

This property is very magical. If metallic hydrogen can be retained for a longer period of time, evaporate slower, and release energy gently, it will be equivalent to a very, very efficient battery.

Although its energy density is not as good as nuclear fission and nuclear fusion, it can be made very compact and can store more power than traditional aluminum-air batteries. For now, it's still very useful.

Metal hydrogen can also be used to make a "magnetic cage" that confines the plasma to "contain" the hot ionized gas. This can be said to be the latest version of controllable nuclear fusion.

Of course, crazy scientists no longer care about things like "nuclear fusion" that have already been realized. They plan to complete a quark energy research experiment at the core of the metallic planet!

Metallic hydrogen is a necessary experimental material.

At an ultra-high temperature of one trillion degrees, protons and neutrons will also completely melt and become a plasma composed of quarks and gluons. This pot of "quark soup" can convert mass into energy under certain conditions. Heavier quarks quickly become up or down quarks through a process called particle decay. Particle decay is the process of changing from a high-mass state to a low-mass state.

Ordinary nuclear fusion has a mass-to-energy conversion efficiency of about 3% to 7%. Using quark-level conversion, approximately 40% of the mass can be converted, which can be said to be an order of magnitude higher!

"Ordinary nuclear fusion is enough... The materials for nuclear fusion are almost endless. This kind of quark energy..." Yu Yifeng was quite speechless when he saw this experimental plan. Are these researchers bored to this point?

Generally speaking, nuclear fusion can fully meet the needs of new humanity. Whether it is to propel the planet or other industrial activities, the energy generated is sufficient.

Now we have to work on the extremely difficult quark energy... No matter from any angle, the high temperature of trillions of degrees and the atmospheric pressure of millions are many times more difficult than nuclear fusion.

The increased energy is only one order of magnitude. What is used is still the conversion of mass and energy, and there is no essential change.

"The conditions for the formation of quark soup 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 tiny irregularities. This experiment is conducive to our understanding of the high-dimensional universe. Understanding..." Professor Ding said calmly, while taking out a series of professor signature lists from his pocket.

"Moreover, if you want to produce antimatter in batches, you must start from the quark level...a large amount 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 a better choice to start at the quark level. After all, all elementary particles originate from the vacuum. A meson is composed 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 the strong interaction, 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 activity. And he doesn't think that scientists can find anything useful. At most, they are just curious.

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

After receiving the reply, Professor Ding Yidong left with satisfaction.

Next, Gaia's creature Ling also made her own request: She hopes to add a super-large ocean to the surface of the planet!
