Voyage of the Stars

The first point requires that most level 3 civilizations can achieve it. A civilization with normal development and good computer technology can have the industrial strength to build an astronomical particle collider. It's just that some civilizations are stronger, so the construction time is shorter and the life of the creation is longer.

Of course, to build such a creation, the civilization also needs to have the courage to burn the boats.

As for the second point, basically all level 3 civilizations cannot do it. So theoretically, level 3 civilizations will never discover the experimental anomalies of astronomical particle colliders. Fortunately, the technology in this universe seems to have traces to follow. This road is blocked by a tall wall, and there is a hidden window on the other side, allowing civilizations to peek at the clues on the other side of the high wall through this window.

This window is the basic theory of the unrestrained and far beyond the application technology of this civilization.

Don't think that every civilization is like this just because humans have a large number of theories that are completely impossible to realize. In fact, it is quite the opposite. For example, in the database of the Chiyan civilization, humans have not found any traces of string theory and superstring theory.

They did infer from some information about the "super-distance communication core" component that has been in the hands of humans that there is a way of communication in the universe that exceeds the speed of light, which is likely to be a different kind of particle. They also named this speculative particle, and also concluded that this particle has negative mass, and is inherently super-light speed, but the slower it acquires energy, etc., which are similar to the characteristics of tachyons in human theory.

But that's all.

So if there is no accident, the Red Flame Civilization will most likely be trapped and killed at the peak of the third-level civilization, after all, they can't even produce strong artificial intelligence independently.

So what is this tachyon-related theory? Humans happen to have it, although humans don't know whether this theory is correct or not.

In the human knowledge base, there are descriptions of this aspect.

That is the membrane in string theory, the D0 membrane-related discussion. So what is the D0 membrane? To understand the D0 membrane, first know what the membrane is, and then what the D-membrane is.

As for the membrane, as we all know, Zhou is a description in string theory and superstring theory, a structure of the string. And the D-membrane is a special membrane. Humans define it as follows: the D-membrane is where the string ends in space.

So what about the D0-membrane? First of all, we know that a string is a 1-brane. A point particle is a 0-brane. A membrane-like object is a surface at any given time, a 2-brane. There are similar 3-branes, 4-branes, two 5-branes, 6-branes, 7-branes, 8-branes, and 9-branes.

So it is easy to understand that D0-brane is a point particle.

It has mass. If string theory is used to explain quantum fluctuations, then it is the movement of the taut string between two D0-branes, and their movement is the quantum fluctuation phenomenon.

So what is its relationship with tachyons?

Of course it is related, point particles and particle colliders! From the perspective of string theory, some of the point particle collisions such as electron-electron and electron-anti-electron in the astronomical particle collision experiments conducted by humans are collisions of D0-branes.

So the question is, from the perspective of string theory, what phenomenon will the collision of D0-branes produce?

The answer is that the mutual annihilation of D0-branes and anti-D0-branes, in addition to producing strong radiation, also has a negative value about quantum fluctuations that is difficult to remove mathematically. Theory holds that it is a tachyon, something with imaginary mass.

When a D0-brane and an anti-D0-brane move away from each other, there needs to be enough energy to tighten the string to exceed the negative contribution of quantum fluctuations. At this time, the tachyon hidden in the laws of the universe is very stable. When a D0-brane and an anti-D0-brane approach each other, because they have mass, they will attract each other gravitationally. However, because they have the same neutral charge, their attraction will be offset by repulsion. As a result, both sides can hardly perceive the existence of each other. At this time, the tachyon is in an almost stable state.

When the D0-brane and the anti-D0-brane are too close, these strings will become tachyons, which can also be said to be the tachyons hidden in the laws of the universe are in an unstable state. When the D0-brane and the anti-D0-brane really collide and annihilate each other, the tachyons hidden in the laws of the universe will roll away, rolling down from the apex of the quantum fluctuation and becoming a definite tachyon.

If the tachyons appear and leave the collision laboratory, then obviously the conservation of mass and energy before and after the experiment will change, but this phenomenon is affected by the fluctuation of the Higgs mechanism, so that the technology of the third-level civilization cannot detect any change in the conservation of mass and energy.

If we look at the experiment from the "window" of string theory, there will be no such result, and we will find that something has escaped.

Of course, the so-called "discovery" here is not a real discovery, but only a discovery based on the mathematical derivation of string theory, not a precise and intuitive measurement by humans from experiments.

String theory certainly has unexplained problems, but it happens to be used to explain the situation that humans are facing today.

But then again, if humans only encounter this situation and do not have the "super-distance communication core" obtained from the Red Flame Civilization, then they probably will not think of the connection. Even if they think of looking at the problem from the perspective of string theory, they will not realize that the deviation of the calculated values ​​is caused by the tachyons, but will think that it is a wrong theory and wrong calculation.

If so, even if humans have many basic theories that surpass applied technology, they will not think about this, unless one day they are lucky enough to find a creation about long-distance communication from a level 4 relic and understand its approximate working method.

It can be seen from this that the barriers of level 4 civilization are not so easy to break. It requires this civilization and this race to have a strong imagination and extremely good luck, otherwise this civilization may be trapped in this stage because of its rigid thinking.

Of course, luck is not absolute. After all, although some civilizations do not have level 4 civilization creations as inspiration, they can still realize the problem through "flash of inspiration". This is inevitable, otherwise there will be no first civilization to set foot on level 4 civilization.

However, the discovery of tachyons is not the end, because humans know very well that the symbol of level 4 civilization is not the discovery of tachyons, but the grand unified theory. And speaking of it, humans are not really discovering tachyons now. After all, humans have not detected tachyons at all. If this theoretical explanation is correct, then it is only an indirect discovery.

And what is the relationship between the tachyons that appeared in the experiment and the grand unified theory? Humans still don't know.
