Membrane Mutual Annihilation

The first requirement is achievable by most Level 3 Civilization. A normally developed civilization with decent computer technology can possess the industrial capability to build Astronomical-Level Particle Collider. It's just that some civilizations are more powerful, so the construction time is shorter and the lifespan of their creations is longer.

Of course, creating such a creation also requires that civilization to have the courage to Burn the Boats.

As for the second point, it's practically impossible for any Level 3 Civilization to achieve this. So theoretically Level 3 Civilization would never be able to detect the experimental anomalies of Astronomical-Level Particle Collider. Fortunately, the technology in this universe seems to have a way of working. This path is blocked by a high wall, but there is a hidden window on the other side, allowing civilizations to peek through this window at the clues on the other side of the high wall.

This window contains the foundational theories of unbridled imagination that far surpass the applied technologies of our current civilization.

Don't assume that every civilization is like this just because humanity possesses a large number of theories that are completely impossible to realize. In fact, quite the opposite is true. For example, in the Crimson Flame Civilization, no trace of String Theory or Superstring Theory has been found in the civilization's database.

They deduced from some data of the 'Hyperdistance Communication Core' component that had already come into human hands that there exists a communication method in the universe that exceeds the speed of light, possibly a different kind of particle. They even named this hypothetical particle and concluded that it has Negative Mass, is faster than light, and gains energy more slowly, etc., characteristics similar to Tachyon in human theory.

But that's all.

Therefore, barring any unforeseen circumstances, the Crimson Flame Civilization will most likely be trapped at the peak of Level 3 Civilization, since they are unable to even produce Strong Artificial Intelligence independently.

So what is this theory related to Tachyon? Humans happen to have it, although we don't yet know if it's correct.

Descriptions of this exist within the human knowledge base.

That refers to the membranes in String Theory, specifically the D0-brane. So what is D0-brane? To understand D0-brane, we first need to know what a membrane is, and then what D-Membrane is.

A membrane, as everyone knows, is a description in String Theory and superstring String Theory, a structure of a string. D-Membrane, however, is a special kind of membrane, defined by humans as: D-Membrane is where a string ends in space.

So what about D0-Membrane? First, we know that a string is a 1-membrane. A point particle is a 0-membrane. A membrane-like object at any given time is a surface, which is a 2-membrane. Similarly, there are 3-membranes, 4-membranes, two types of 5-membranes, 6-membranes, 7-membranes, 8-membranes, and 9-membranes.

Therefore, it is easy to understand that the D0-Membrane is a point particle.

It has mass. If we use String Theory to explain quantum fluctuations, then it is the motion of a taut string between two D0-Membrane. This motion is the phenomenon of quantum fluctuations.

So what does it have to do with Tachyon?

Of course it's related—point particles and Particle Collider! From the perspective of String Theory, some of the point particle collisions in Astronomical-Level Particle Collision Experiment conducted by humans, such as electron-electron and electron- Anti-Electron collisions, are essentially D0-Membrane collisions.

So the question arises: from the perspective of String Theory, what phenomena would occur during D0-Membrane collisions?

The answer is that the mutual annihilation of the D0-Membrane and anti-D0- Membrane Mutual Annihilation, besides producing intense radiation, also generates a mathematically difficult-to-eliminate negative value related to quantum fluctuations. Theoretically, this is the Tachyon, something with imaginary mass.

When a D0-Membrane and an Anti-D0-Membrane move away from each other, sufficient energy is needed to tense the string beyond the negative contribution of quantum fluctuations. At this point, the Tachyon, hidden within the laws of the universe, is very stable. When a D0-Membrane and an Anti-D0-Membrane approach each other, they are attracted to each other by Gravity because they have mass. However, because they carry the same neutral charge, their Gravity is canceled out by repulsion, resulting in the two being almost unaware of each other's presence. At this point, the Tachyon is in a nearly stable state.

When the D0-Membrane and Anti-D0-Membrane get too close, these strings become Tachyon, or in other words, the Tachyon hidden in the laws of the universe are in an unstable state. When the D0-Membrane and Anti-D0-Membrane actually collide and annihilate each other, the Tachyon hidden in the laws of the universe will roll away, falling from the peak of quantum fluctuations, and becoming definite Tachyon.

Tachyon appear and leave the collider, then obviously the mass-energy conservation before and after the experiment will change. However, this phenomenon is affected by the fluctuations of the Higgs Mechanism, so much so that the technology of Level 3 Civilization cannot detect any change in the mass-energy conservation.

However, if we look at the experiment through the 'window' of String Theory, we will not get this result; we will find that something has gone missing.

Of course, the so-called "discovery" here is not a real discovery, but only a discovery based on String Theory mathematical derivation, rather than something that humans actually measured precisely and intuitively from experiments.

String Theory certainly has problems that it cannot explain, but it can be used to explain the situation that humanity is facing today.

However, if humanity only encountered this situation and did not possess the 'Hyperdistance Communication Core' obtained from the Crimson Flame Civilization, they probably wouldn't have thought of the connection. Even if they did consider looking at the problem from the perspective of String Theory, they wouldn't realize that the deviation in the calculated values was caused by Tachyon, but would instead think it was due to incorrect theory or calculations.

If that's the case, even if humanity has fundamental theories that far surpass applied technology, it won't think in this direction, unless one day it gets incredibly lucky and finds an artifact related to Hyperdistance Communication in some Level 4 Ruins, and can understand its general workings.

This shows that the barriers of Level 4 Civilization are not so easy to break through. It requires that the civilization and race have a strong imagination and extremely good luck. Otherwise, the civilization may be trapped at this stage indefinitely due to rigid thinking.

Of course, luck isn't everything. After all, some civilizations, even without the creations of Level 4 Civilization to inspire them, can still realize the problem through a "flash of inspiration." This is inevitable; otherwise, there wouldn't have been a first civilization to reach Level 4 Civilization.

However, the discovery of Tachyon is not the end of the story, because humanity knows very well that the hallmark of Level 4 Civilization is not the discovery of Tachyon, but the Grand Unified Theory. Moreover, in a sense, humanity hasn't truly discovered Tachyon yet, since we haven't detected Tachyon at all. If the theory is correct, then it can only be considered an indirect discovery.

The relationship between the Tachyon observed in the experiment and the Grand Unified Theory remains unknown to humankind.
