Start sweeping the universe by rubbing the CPU with your hands.

At this stage, the scientific research capabilities of human civilization have once again come in handy.

At this stage, the human scientific community is unable to make breakthroughs in universal theories such as M theory, but at this moment Han Yang has completed the most important breakthrough, and then teaches it to human scientists and lets them learn it, then One learns faster than the other.

There is no way, I have been studying for the past hundreds of years, and the screening has been completed long ago, and all the people with the strongest learning ability have been screened out.

After completing the study, it is also not a problem to do some applied and micro-innovative research.

This is the strength of human civilization at this stage.

Of course, with the presence of Han Yang, this process will advance faster.

Otherwise, even if a breakthrough in basic theory is achieved, it will be almost impossible to truly transform it into combat effectiveness within 100 years.

At this moment, Han Yang and the human scientific community are facing the most basic and important issue.

Gravity conversion problem.

The transformation of gravity is the foundation of all the iconic technologies of level four civilizations.

To put it simply, use the energy of other properties to convert it into gravity, or offset gravity.

With the support of M theory, which can truly be called the theory of everything, completing this transformation becomes an engineering problem, not a theoretical problem.

Just like when humans mastered the theory of relativity, creating an atomic bomb was only an engineering problem and no longer a theoretical problem.

In order to solve this engineering problem, Han Yang once again began to invest a lot of computing power. At the same time, all scientists related to this in the entire human scientific community also invested all their energy in it after completing their preliminary studies.

One after another, huge research institutions were established, and one after another, laboratories filled with sophisticated equipment were put into operation. After more than ten years of busy work, Han Yang finally made a breakthrough.

Eris, Gravity One Laboratory.

Standing on the dark and cold earth are two ultra-large-scale nuclear fusion power stations, which produce a huge amount of electricity at all times and supply the operation of an equally huge research institution.

Mountains of equipment can be seen everywhere here. The huge factory building with a height of more than 20 meters is inconspicuous here.

A large amount of energy from the fusion power station is gathered in, and after being transformed by huge scientific research equipment one after another, it is finally gathered into a laboratory with an area of ​​less than 50 square meters at the core.

At the heart of this laboratory is a glass box. Inside the glass box is an extremely pure vacuum. At the same time, maintained by numerous devices, its internal temperature is only one 20th of a degree higher than absolute zero.

Absolutely pure, absolutely cold.

Inside this glass box, there is a thin piece of metal.

It is only a few microns thick and weighs less than a thousandth of a gram.

But even if it is so light, even if Eris is just a dwarf planet with weak gravity, it can still only fall on the tray honestly.

The planet's gravity still acts on it, binding it.

But with the arrival of a burst of energy, everything changed.

Under the eyes of the scientists who were watching closely through observation equipment, and under the eyes of Han Yang, in the extremely high vacuum glass box, the piece of metal suddenly slowly levitated.

No, it wasn't actually that it levitated, but that the test chamber sank a little.

But the key question is that if the test box sinks, shouldn't this piece of metal also sink in a gravity environment?

But no!

At this moment, it broke free from the gravitational field of Eris and no longer followed the tray.

The pallet sinks, but it floats.

Suspended without any support or power.

Gravity shielding was realized at this moment.

But it's not over yet. The next moment, following some operations by the scientists, the piece of metal suddenly quickly fell onto the pallet.

The gravitational acceleration of Eris is about 0.8 meters per second, that is, if an object is in free fall, it will accelerate by 0.8 meters per second.

This piece of metal was undoubtedly in free fall just now. However, the instrument showed that the acceleration of its previous fall reached 1.2 meters per square second.

It exceeds the gravitational acceleration of Eris by about 50%!

This incredible scene was truly displayed in front of the scientists.

The previous unsupported suspension was gravity shielding. The current accelerated fall is due to increased gravity!

Although the energy of two large nuclear fusion power stations was exhausted, in the end they only operated such a small thing with a mass of less than one thousandth of a gram. Although there was a gap of hundreds of millions of times in the input-output ratio, when this scene really appeared in In front of people, in the conference room of the Gravity No. 1 Laboratory, the senior government officials, outstanding scientists, military personnel, etc. who came to watch the ceremony burst into warm cheers at the same time.

In an instant, cheers and applause resounded throughout the large conference room. Some were even so excited that they hugged each other and shed tears of excitement.

After so many years, so many generations of struggle, so many generations of sacrifices, finally, for the first time in history, control of gravity was achieved...

Although this piece of metal is small, the hope contained in it is so vast.

Just think about it and you will know how broad the prospects are.

The first is for spacecraft.

Until now, there is no gravity in the spaceships built by humans or any other third-level civilization.

Even if there is, it is only artificial gravity created through rotation, and its essence is actually centrifugal force.

But now, if the gravity conversion technology is mastered, then constructing artificial gravity through rotation will become a thing of the past.

Even on a plane, people can directly create gravity through relevant technologies.

But this is actually just a very small application.

With this technology, the key point is that it can create gravitational shielding.

As we all know, there is an upper limit to the gravity that the human body, or other life forms of alien civilizations, can withstand.

For example, for humans, once the gravity exceeds 20 times the earth's gravity, the human body will be damaged if it remains for a long time. When the gravity reaches 70 times or higher, humans will die in just a few seconds.

This limits the spacecraft's ability to accelerate.

20 times the Earth's gravity corresponds to an acceleration of about 200 meters per square second, and 70 times the Earth's gravity corresponds to an acceleration of 700 meters per square second.

In other words, even if it is a space battleship, even if it is very thirsty for maneuverability, it cannot maneuver more than 700 meters per square second. Because once this speed is exceeded, all the soldiers in the battleship will die.

However, the theoretical propulsion capability of thrusters developed by humans has already exceeded 1000 meters per square second.

This means that the structural strength of the human body limits the maneuverability of the battleship.

But now, with the emergence of gravity conversion technology, this restriction has been directly lifted.

After applying this technology, even if the battleship's maneuverability is as high as 10,000 meters per square second, the soldiers inside the battleship will not feel any inertia at all. No matter how violent the maneuvers, they can always stand steadily on the ground, truly walking on flat ground.

How much does this improve the battleship's combat effectiveness? It’s unimaginable!
Secondly, this also indicates the potential feasibility of a new type of weapon.

For example...gravity bombs, or gravity shields, and gravity cannons.

Through a certain technology, the bomb has super strong gravity, even comparable to that of a white dwarf star or a neutron star. It uses gravity to attract all surrounding tangible and invisible objects and destroy them.

As for the gravity shield, it can create a certain gravity field on the spacecraft to deflect the trajectory of the incoming shrapnel so that it cannot hit the hull.

For gravity cannons, gravity technology can be used to accelerate projectiles, making them more lethal than energy cannons.

Gravity shielding, gravity enhancement, gravity bomb, gravity shield, gravity cannon...

This small piece of metal indicates a vast sea of ​​stars behind it.

Through this test, Han Yang and the human scientific community comprehensively verified the engineering feasibility of controlling gravity.

With engineering feasibility in mind, all that needs to be done is miniaturization and stabilization.

This part of the work can be left to the human scientific community, or at least a large part of it can be undertaken. Han Yang's main energy at this moment was transferred to another direction.

A direction that is also extremely important and critical.

Changes in how energy is obtained.

At level three and earlier, intelligent life relies on chemical energy, nuclear fission energy, and nuclear fusion energy to obtain energy.

Among them, chemical energy comes from the disruption and reorganization of matter molecules. For example, combustion is the oxidation process of the chemical elements that make up matter.

Nuclear fission and nuclear fusion come from the disruption and reorganization of atomic nuclei.

This process achieves basic changes in the properties of matter. For example, the fission of uranium causes the uranium to become a variety of lower-density metallic elements.

The fusion of hydrogen also results in the conversion of hydrogen into other elements.

In this process, nuclear fusion, especially the fusion of protium, produces the highest energy, which can even reach about 0.7% of the mass.

But compared to the overall mass, this energy conversion efficiency is still too low.

It is almost unimaginable to rely on such a magnitude of energy acquisition methods to support various iconic technologies of a fourth-level civilization.

But it doesn't matter. After fully mastering M theory, Han Yang found a more efficient way to obtain energy.

A more fundamental way of obtaining energy from subatomic particles than from the atomic nucleus level.

Quark fission!

By manipulating the four basic forces, Han Yang will be able to break the quark confinement and release the strong interaction force trapped inside subatomic particles as energy.

In a subatomic particle, such as a proton, neutron, etc., the quark itself only contributes about 1% of its mass.

The remaining 99% exists in the form of strong interaction field energy. That is to say, it is precisely because of this energy that all the materials that people come into contact with every day, whether it is the earth or the air, whether it is the table or the food, will have the current quality.

Without this energy, the mass of all matter would be reduced to 1% of its original mass.

There is so much energy contained in subatomic particles, but people in the past could only look forward to it and be unable to use it at all.

But now, after mastering M theory, everything is different.

Han Yang has found the key to harnessing this energy.

The key to this key lies in gravity. To be more specific, it is a sufficiently strong gravitational field.

The gravitational field is strong enough, and with a certain pressure and temperature, this energy can be extracted.

Ideally, the energy that can be extracted by quark fission can even account for 14% of the total mass of matter! It is 20 times the energy that can be extracted by protium fusion!
In other words, after innovating the energy acquisition method, the original ideal combat time of a warship was only two months, but now it can be directly increased to 40 months!

This is a higher level of energy utilization than nuclear fusion.

At the edge of the solar system, two dark and icy asteroids are orbiting each other.

In the human star catalogue, these two asteroids are called the Soul Stars.

On the Soul God Star, a huge base has been built.

It is surrounded by tall buildings forming a circle. In the middle of the building is a hemispherical building.

The core of the hemispherical building is a huge equipment with a height of more than ten meters and a diameter of seven to eight meters.

It's full of complicated pipes and thick cables. The energy from the surrounding nuclear fusion power plants continues to pour in, and is converted into gravity through a series of complex equipment, giving it a gravity field equivalent to 1.2 times the earth's gravity.

Among them, some pure gold elements were put into the core of the reaction chamber.

In the super strong gravity field, through a series of magical changes based on M theory, a huge amount of energy was suddenly released from these gold elements.

It was like a fiery sun suddenly appeared on the planet, and the dark night sky was instantly illuminated. With the release of endless light and heat, the entire planet shook.

The people observing here from space cheered at the same time after seeing this scene.

Because people have confirmed that just before, an unprecedented explosion occurred on this asteroid.

Not a chemical explosion, not a nuclear explosion, but a type of explosion that has never been seen before.

Quark fission explosion!

The energy trapped in subatomic particles was finally extracted for the first time in human history.

It is only one kilogram of gold element, of which about 140 grams of mass is converted into energy, releasing about 1.26*10^16 joules of energy, which is approximately equivalent to the energy released by the explosion of 300 million tons of TNT explosives!
At this moment, although humans can only achieve uncontrollable quark fission, causing energy to be released all at once and causing a violent explosion, but since the extraction of this energy can be realized in engineering, then it can be further made controllable, and the same It's just an engineering problem.

Just like, after the atomic bomb is built, will the emergence of nuclear fission power plants be far away? (End of chapter)
