Chapter 215 Heavy Nuclear Fusion

After sending the mothership away, the human fleet, under the order of Yue Yuan, destroyed and massacred the remaining residential ships of the Kuntai civilization.

Except for the Tianqin, all other Shan-class warships were present, including all the human Ganymede-class warships and frigates. Under Manyuemei's wave, they all started to massacre the residential ships of the Kuntai civilization.

97 residential ships and more than 6 million Kuntai people had no resistance. In less than ten minutes, they were all turned into cosmic garbage under the intensive artillery fire.

Pierce's plan to wait for the broadcast of the Galactic Heart Alliance also turned into dust floating in the Aldebaran star system with the roar of human warship guns.

It can be said that Yue Yuan was the culprit of this real Kuntai massacre, but he did not feel any guilt. Of course, he was not aware of Pierce's plan.

From giving orders to the destruction of all Kuntai residential ships, he watched the whole thing. After that, he turned around and devoted himself to his work.

The resistance consciousness of Kuntai civilization was finally completely wiped out. The remaining more than 10,000 newborns will be kept in captivity by humans and then participate in the research of human life sciences.

The database of a civilization is very comprehensive. Even though the Kuntai civilization here is also a civilization that has lost its mother planet, and has lost a lot like humans, their preparations are still sufficient. Although the entire technology tree has been lost, it is not as serious as humans.

So in addition to life sciences and cold nuclear fusion, humans have also dug out many things from the database of Kuntai civilization.

Like Kuntai civilization's computer technology, cosmic model theory, standard particle model, as well as humanities and social data, ideology, etc.

Of course, except for cold nuclear fusion, all other technologies are at the first-level civilization level.

However, even at the first-level civilization level, many theories are ahead of humans, such as heavy nuclear fusion.

The research on heavy nuclear fusion by Kuntai civilization has lasted for thousands of years. The reason for the lack of progress is clearly written in their database, that is, the limitations of particle physics, so in the end, Kuntai civilization has to find back the magnetic confinement that has been abandoned for many years.

After knowing this, human physicists followed this line of thought and began to blow the horn of attack on heavy nuclear fusion technology.

The principle of hydrogen bomb is to use the fusion reaction of hydrogen isotopes, which is generally triggered by the fission of atomic bombs. The reason is very simple, that is, temperature and pressure.

Today, humans have mastered the fusion of hydrogen and helium nuclei. These two elements are lighter elements, that is, elements with atomic sequences at the front of the periodic table. Therefore, this kind of nuclear fusion is also called light nuclear fusion.

Obviously, heavy nuclear fusion is the nuclear fusion that allows the elements later in the periodic table to undergo nuclear fusion.

The principles of the two are the same, both are nuclear fusion, mass loss, and energy generation.

However, the technical difficulty is not at the same level.

The heavier the atomic nucleus, the higher the temperature and pressure required for fusion.

Take stars as an example. Stars have huge gravitational force, which makes them have strong centripetal pressure, so the temperature requirements for nuclear fusion on stars are relatively low.

Generally speaking, the temperature required for hydrogen nuclear fusion in stars is 10 million Kelvin, which is 10 million minus 273.15 degrees Celsius, which is rounded to about 10 million degrees Celsius.

Helium fusion temperature requires 200 million Kelvin, corresponding to a star size of 0.5 times the mass of the sun and a density of 6*10 squared grams per cubic centimeter. This means that in order for helium nuclei to fuse, the environment that meets the requirements must have a temperature of at least 200 million Kelvin and an equivalent internal pressure environment produced by an object of 0.5 times the mass of the sun.

Carbon nuclear fusion temperature requires 800 million Kelvin, corresponding to a pressure environment of 4 solar masses. Oxygen nuclear fusion requires 1.5 billion Kelvin, corresponding to an environment of 6 solar masses. Silicon nuclear fusion requires 3.5 billion Kelvin, corresponding to an environment of 9 solar masses.

From this, it can be seen that if humans want to achieve heavy nuclear fusion, they must at least be able to create a temperature environment of 800 million Kelvin. If they want to "burn stones" to produce the final product iron, they must have 3.5 billion Kelvin and create a pressure environment of up to 9 solar masses.

If such a high temperature is to be resisted by materials, there is no material that can withstand it. After all, the most powerful material currently used by humans can only withstand a temperature of 150 million degrees Celsius, and the pressure is even more different. It is still far from enough.

In fact, humans have the ability to create temperatures higher than these temperatures. For example, the proton collider located at the European Center for Nuclear Research has created 10 trillion degrees Celsius.

Of course, these are the temperatures at that moment. The volume is too small, and it is only the temperature. Humans cannot create such a high continuous temperature.

In other words, humans have not mastered the technology of final nuclear fusion in one step.

There is no way to achieve it in one step, so human scientists will find another way and proceed step by step. If the pressure conditions are too high to be achieved, then increase the temperature and reduce the pressure, and vice versa.

Just like oxygen nuclear fusion, a pressure environment of 6 solar masses requires 1.5 billion Kelvin, but if it is changed to a pressure environment of 10 solar masses, the temperature will become 200 million Kelvin.

The same is true for silicon nuclear fusion. If a pressure environment of 20 solar masses can be achieved, it only needs 300 million degrees Celsius to achieve it.

What human scientists need to do now is to combine their own technology with that of the Kuntai civilization to conduct repeated experiments on these various possible conditions for heavy nuclear fusion.

Humans have made great achievements in magnetic confinement, while Kuntai civilization has made great achievements in inertial confinement. Magnetic confinement is good at increasing temperature, while inertial confinement is good at increasing pressure. Now humans are just holding the highest technology of both to impact the peak of nuclear fusion technology.

Humans, we must master the power that exceeds the sun.

Yes, it exceeds the power of the sun, but not the power of supernovas.

The power of supernovas can create all heavy elements after iron, but heavy nuclear fusion cannot, because its final product is iron, which is still many orders of magnitude away from the power of supernovas.

Even though it is still far behind the power of supernovas, it is still very, very difficult for humans at present.

Even the terrifying temperature and pressure conditions seem to be more desperate than cold nuclear fusion.

Of course, it only looks like it. In fact, if there is no Kuntai civilization's mature cold nuclear fusion technology, humans are still in the stage of theoretical demonstration of the feasibility of cold nuclear fusion.

From this point of view, cold nuclear fusion is the technology that does not see hope, not heavy nuclear fusion. Fortunately, humans have obtained a full set of ready-made cold nuclear fusion theories and technologies.
