Voyage of the Stars

After sending the mother body away, the human fleet, under Yue Yuan's order, destroyed and massacred the remaining residential spaceships of Kuntai Civilization.

Except for the Tianqin, which did not participate, all other Shan-class battleships were present, including all human Callisto-class battleships and frigates. Under Man Yuemei's wave, they all massacred the spaceships inhabited by the Kuntai civilization.

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

Pierce's plan to wait for the Galactic Alliance broadcast also turned into dust floating in the Aldebaran galaxy along with the roar of human naval guns.

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

From the time he gave the order to the destruction of all Kuntai's residential spaceships, he watched in full. After that, he turned back and devoted himself to his work.

The resistance consciousness of Kuntai civilization has been completely eliminated in the end, and 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 the Kuntai civilization here is a civilization that has lost its home planet. It has lost a lot like humans, but their preparations are sufficient. Although the entire technology tree has been lost, it is not as good as humans. serious.

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

Such as Kuntai civilization's computer technology, universe model theory, standard particle model, as well as humanistic 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 mankind, such as heavy nuclear fusion.

The Kuntai civilization has been researching heavy nuclear fusion for thousands of years. The reason for not making any further progress is clearly written in their database, which is the limitation of particle physics. So in the end, the Kuntai civilization will have to re-process the materials that have been discarded for many years. Magnetic confinement retrieved.

After knowing this, human physical scientists followed this idea and began to sound the clarion call for heavy nuclear fusion technology.

The principle of the hydrogen bomb is to use hydrogen isotopes to carry out a fusion reaction. This reaction is usually triggered by the fission of an atomic bomb. The reason is simple: temperature and pressure.

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

Obviously, heavy nuclear fusion is the nuclear fusion that enables elements further down the periodic table to undergo nuclear fusion.

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

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

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

Take stars as an example. Stars have huge gravity, which gives them strong centripetal pressure. Therefore, the temperature requirements for nuclear fusion that occur on stars are relatively low.

Generally speaking, the temperature required for stellar hydrogen core fusion is 10 million Kelvin, which is 10 million minus 273.15 degrees Celsius, which is almost 10 million degrees Celsius when rounded.

The temperature of helium fusion requires 200 million Kelvin, which corresponds to a star size of 0.5 times the mass of the sun and a density of 6*10 quadratic grams per cubic centimeter. This means that for helium nuclei to fuse, the required environment must be a temperature of at least 200 million Kelvin and an equivalent internal pressure environment generated by an object with 0.5 times the mass of the sun.

The temperature of carbon nuclear fusion 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.

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

If materials are used to withstand such a high temperature, no material can withstand it. After all, the most powerful material currently available to humans has a high temperature resistance of only 150 million degrees Celsius, and the pressure gap is even greater. Too far off.

In fact, humans have the ability to create temperatures higher than these temperatures. For example, at the Proton Collider at CERN, humans have created temperatures exceeding 10 trillion degrees Celsius.

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

In other words, mankind does not have the technology to master the ultimate nuclear fusion in one step.

If there is no way to get it done in one step, human scientists will find another way and proceed step by step. If the pressure condition is too high to achieve, 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. If it is replaced by 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 will only require 300 million degrees Celsius.

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

Humans have made great achievements in magnetic restraint, and Kuntai civilization has made great achievements in inertial restraint. Magnetic confinement is good at increasing temperature, and inertial confinement is good at increasing pressure. Now mankind is just holding the two highest technologies to hit the pinnacle of nuclear fusion technology.

Human beings want to master power that exceeds that of the sun.

Well, yes, more than the power of the sun, but not the power of a supernova.

The power of a supernova can create all heavy elements after iron. Heavy nuclear fusion cannot do this because its final product is iron, which is still many orders of magnitude behind the power of a supernova.

Even though it is much worse than the power of a supernova, it is still very, very difficult for humans at present.

Even the appalling temperature and pressure conditions seem more desperate than cold fusion.

Of course, this is just a look. In fact, without Kuntai civilization’s already mature cold nuclear fusion technology, humans would still be at the stage of theoretical demonstration of cold nuclear fusion.

From this point of view, cold nuclear fusion is a technology with no hope, not heavy nuclear fusion. Fortunately, mankind has obtained a complete set of ready-made cold nuclear fusion theories and technologies.
