If a beam of light is two-dimensional, its distance change in two-dimensional space is always between two points. However, in three-dimensional space, this coordinate changes. When two-dimensional beings measure the speed of light, they need to add an angle and use the Pythagorean theorem to calculate the distance the light travels. But if this beam of light is truly two-dimensional, its changes are not limited to the angle; it will also be affected by the curvature of space in three-dimensional space. Even a gust of wind can bend this beam of light, causing great trouble for two-dimensional beings.
The situation is similar when light travels from three dimensions to four dimensions. Light is three-dimensional, while space is four-dimensional. Light is greatly affected by space. Three-dimensional objects in three-dimensional space can easily withstand changes in space, or in other words, can easily influence space, because matter itself is also a high-density space. However, three-dimensional objects cannot influence four-dimensional space; on the contrary, four-dimensional space can easily influence three-dimensional objects.
The same applies to warships. However, warships carry a massive amount of energy, and their enormous and sturdy size, along with some simplified four-dimensional structures, allows them to withstand the changes in four-dimensional space.
However, three-dimensional is still three-dimensional. Even if a three-dimensional object is designed as a four-dimensional structure, its most basic building block is still Three-Dimensional Basic Space.
Although the fourth dimension is full of energy, there is no four-dimensional matter, which puzzles the academicians. Logically, Basic Energy constitutes matter. Academician Li Youwei has also studied the energy here, but the energy here is no different from the Basic Energy of the three-dimensional universe. In other words, Basic Energy has a three-dimensional structure. But why would three-dimensional Basic Energy form a four-dimensional space? This is a major headache for the academicians.
After returning from the Tree Race Academician Liu stayed in the fourth dimension, trying to find the Four-Dimensional Basic Space- dimensional universe. However, after many years, he still made no discovery. Academician Liu and Academician Li tried to synthesize matter here using Basic Energy. They were still able to synthesize all the matter particles in the three-dimensional universe, but they were all three-dimensional structures, and not a single particle had a four-dimensional structure.
Academician Liu and Academician Li hope to find Four-Dimensional Basic Space or four-dimensional matter. If they cannot find it, they will synthesize a four-dimensional matter themselves. In addition to four-dimensional matter, there is also two-dimensional matter. Currently, they are using energy collisions to change space and generate a macroscopic Two-Dimensional Basic Space.
If we could use these macroscopic Two-Dimensional Basic Space to synthesize Two-Dimensional Basic Energy, and even further synthesize two-dimensional matter to create true two-dimensional weapons, then human fleets would be fearless. The current two-dimensionalization of warships can only play a role in surprise and make them difficult to defend against. If they are subjected to a strong attack, these Two-Dimensional Basic Space will not play a significant role.
While two-dimensional matter offers little advantage in manufacturing warships, it is highly effective in creating two-dimensional weapons. Two-dimensional weapons have only one effect: forcing dimensional reduction.
Like other forces, spatial forces tend towards equilibrium. When a four-dimensional space enters a three-dimensional universe, it will experience dimensional reduction because the spatial forces of the three-dimensional universe are far greater than those of the tiny four-dimensional space. A three-dimensional warship entering a four-dimensional space will also be affected by the forces of the four-dimensional space, but it will not ascend in dimension. Dimensional advancement means absorbing energy, which is obviously impossible for a warship because four-dimensional space itself contains three dimensions. Dimensional reduction is like water flowing downhill; it can only go from high to low, not from low to high.
Similarly, if three-dimensional space were to enter a two-dimensional world, it would also experience dimensional reduction. In a three-dimensional universe, it is difficult to reduce dimensions to two dimensions. However, the emergence of two-dimensional matter would be different. If a three-dimensional square or other enclosed space were created using two-dimensional matter, and then this square were compressed, it would bring about a tremendous dimensional reduction explosion. This energy would be far more powerful than the explosion effect of three-dimensional antimatter encasing Two-Dimensional Basic Space. Such an attack occurring inside a warship would likely destroy even the Great Star Region Advanced Civilization, leaving no trace.
Moreover, this has been verified. By using three-dimensional matter in a closed four-dimensional space, the space inside is squeezed in the fourth dimension, which forces the space to shrink. The final effect is the dimensional reduction attack commonly used by fleets.
However, the academicians have no plans to build two-dimensional warships. The current state of two-dimensional overlaying three-dimensional is the most suitable. If the warship were truly two-dimensional, not to mention the difficulty of manufacturing, the defense alone would be overwhelming. Three-dimensional objects could easily destroy two-dimensional warships, and even if applied to two-dimensional weapons, they would be vulnerable to damage. There are many problems that need to be solved.
The fourth-dimensional fleet that remained near the defensive line soon witnessed the attack of those bizarre weapons. Not long after the Exterminator main fleet left, a giant insect leisurely strolled to the vicinity of the defensive line of the five Great Star Region Advanced Civilization, but the warships of the Great Star Region Civilization did not launch an attack.
Instead, the defensive weapons roared in anger. Hu Yu discovered that the energy was flowing towards these defensive weapons. As the energy was continuously drawn out by these weapons, the space in front of the defensive weapons gradually became clearer and brighter. Through observation, Hu Yu discovered that these weapons had actually created a three-dimensional space in the four-dimensional space, directly excluding the fourth dimension.
As space became three-dimensional, the worm suddenly exploded. After the explosion, the defensive weapons stopped working, space returned to its normal four-dimensional state, and the invading worm was reduced to fragments.
Hu Yu showed the video to Academician Zeng and his team. The academicians determined that when these weapons eliminated the fourth dimension, they only eliminated the fourth dimension of space. However, the fourth dimension of space still existed inside the insect. This result was terrifying. Space would be reduced in dimension directly inside the insect, resulting in death. Although the insect was powerful, like a warship, its interior was still fragile and could not withstand such an attack.
As for how these weapons manage to transform four-dimensional space into three-dimensional space, the academicians deduced that it's still an energy issue. These weapons extract energy, and when the energy in space drops to a certain level, a dimensional reduction change may occur. Although the academicians have created a true vacuum in three-dimensional space, where even Basic Energy does not exist, no dimensional reduction occurred. The academicians deduced that three-dimensional space is a relatively stable space, while the stability of four-dimensional space is not so high.
In the Insect Zone at this time.
