At this time, the "Yanyun" shook slightly, started the jump engine, and the window suddenly became dark, because the jump speed of the non-stargate jump reached 1 for the slowest flagship-level starship. 5 AU/s (1 AU = 149,597,870,700 meters), which is 498 times the speed of light (light per second = 300000000 meters), and the fastest jump speed is the shuttle speed can reach 7. 5AU/S, the jump speed of "Yanyun" is roughly 3AU/S, so there is no light outside the window, and the energy carried by conventional starships can only jump arbitrarily in the star system, and if you want to go to other star systems that are often calculated in light years, you must pass through the stargate, the principle of the stargate is to create an artificial space wormhole, which can quickly pass from one star system through the folded space to another star system, but due to the instability of the universe, Only this kind of stellar-to-star folded space is the most stable.

Specifically, the construction of the stargate is based on artificial wormholes and is formed by gravitational resonance in binary star systems. This resonance is equivalent to the friction between gravitational waves of stellar objects. The greater the mass of the celestial bodies, the stronger the resonance between them. The position of the planets in the star system, as well as the complex structure of the dust rings of large planetary bodies, are affected by this resonance phenomenon. Due to the strong resonance phenomenon in binary star systems, the gravitational fields of two stars interfere with each other in a stable binary structure galaxy, just as waves emitted from two wave sources affect each other.

These steady waves form a cascade of standing waves, much like the waves formed by the vibration of the strings when the guitar is played. The strongest resonance is the 1:1 resonance (called the first harmonic), which has two points of stability and one in each of the centers of the two constancies. The second strongest resonance is a 1:2 resonance (called the second harmonic), and its stable point exists at the midpoint of the line between the two stars (assuming that the two stars have equal masses), and so on. At the node, a pair of counterdynamic tensors formed by two rapidly oscillating antigravitational fields produces a strong shear force.

Normally, the interaction between these shear forces is radiated by high-frequency gravitational radiation, without producing any significant macroscopic quantum phenomena. But if this stress (the interaction described above) is confined to a finite range, then this tensor field will eventually form an ever-extending tentacle of high curvature, like a structure in a space-time continuum. Specifically, the tentacles form a self-avoidance four-dimensional flow pattern, causing the tentacles to continuously extend outward. Just like a magnetic field in space-time, the apical curvature of the tentacle reaches its maximum point, and a large enough curvature will cause a small tentacle to form in a distant high-density star field, and the two tentacles will touch and merge naturally.

A similar phenomenon in life is that when lightning strikes the ground, the tip of the lightning actually produces a small lightning bolt that diverges upwards from the ground, and the two merge somewhere above the ground, thus forming a closed current loop. The stargate is primarily composed of a type of sphere called a very large boson, based on a medium-mass fundamental force field and strongly interacting with gravitational waves. The object is filled with super-large boson plasma that reflects gravitational waves, much like the reflection of light from mirrors. By adjusting the density of the plasma, the high-frequency gravitational waves are reflected to counteract the shear tension, and the resulting radiation will be stored in the celestial body, and the internal heavy stress at the resonance point will grow steadily like a network, eventually forming a tentacle with high curvature.

Similarly, lasers produce extremely interfering dense beams of electromagnetic energy by reflecting resonances in cavities. The distance between the ends of the two wormholes depends on the mass of the star in the binary system and the resonance point at which the gate is located. In order to connect the two gates, the application of trial and error is necessary and usually takes many years. This is because we have no way of predicting where the tentacles formed by tensor sites will appear. But by establishing a heavy stress field in nearby galaxies, we don't have to reach a tipping point, and the tentacles are constantly extending. Although it will take a lot of trying, it will be more likely that the two gates will be connected in this way. This is the same reason as using a lightning rod during a thunderstorm.

The first stargate built by the Ellens had a great limitation: once a wormhole had been formed and a ship had already crossed it, another wormhole had to be formed if another ship wanted to pass through. Since it takes days or even months to reconnect the two gates, it takes a lot of time for ships to pass through the gates and wait for the tentacles to rematch. Later "stargate jumps" were built to keep wormholes open for long periods of time, and modern stargates can keep the connection between wormholes open for decades before they reset. In addition, the first stargate built by the Ellens could only connect and keep one wormhole open at a time, whereas nowadays, several wormholes can be kept open at the same time, and the stargate can connect to multiple other gates at once. In an ordinary binary star system, the effective jump distance of the gate is about 15 light-years, with the exception of the gate being built on a second point of resonance between the stars. This is because these nodes are very far away from the star system (usually up to 0 distances. 5 light years), and are more difficult to use, and it is only in the last few hundred years that they have begun to be slowly developed. On the other hand, the gates established at these points have a much larger range of distances than normal gates.

Of course, there are some strict restrictions on crossing the stargate. First, because stargates are built on resonance points, they can only be achieved between galaxies with two or more stars. In this case, one-third of galaxies will not have the objective conditions to build a stargate. Second, in a galaxy, only one gate can be enabled at the same time. This is due to the irregular vibrations that occur in the resonance field generated by the super-large boson spheres, and if there are more than one sphere active in the same galaxy at the same time, then they become extremely unstable and difficult to control. In order for a ship to sail between wormholes, the ends of both wormholes must be connected to their respective gates.

This means that ships can jump in a normal space where wormholes can be created. Because the tentacles will be extremely dilated in the longitude direction, which means that in spatial coordinates, the wormhole will also expand in the longitudinal direction, and the rays will be ring-shaped. If the ship passes through the wormhole, it will have a large tilt, which will inevitably endanger the overall structure of the ship. Of course, this can also be counteracted by the counter-forces of the adjacent ships. Here, the super-large boson sphere also played a significant role in the construction of the stargate. When the spacecraft passes through the super-large boson sphere, a monoatomic layer of a super-large boson will cover the surface of the ship. This surface layer prevents the ship from being stretched and tilted by the resonant field, which protects the overall structure of the ship as it passes through the wormhole. Of course, this does not mean that the tilt is completely non-existent, and even those experienced pilots who have experienced the sensation of the ship leaning down when crossing the wormhole.

Because of the current science and technology, due to the limitation of expensive and scarce energy, generally only flagship-level starships are equipped with ultra-long-range jump engines, but the energy required by conventional starships is charged during sea trials, even if it flies uninterrupted every day as long as the energy compartment is not damaged, it does not need to replenish energy for a lifetime, and it can be maintained in time. The ultra-long-range jump engine for flagship-level starships to jump between star fields, conventional energy can not provide such a huge amount of energy, and can only consume the five kinds of particularly rare energy that are kept secret by various countries so far, such as the "fairy crystal" used by Huaguo's conventional flagship small star carrier and dreadnought, it is said that the super flagship large star carrier and the newly developed other shore use the "divine crystal" with purity far beyond the "fairy crystal", the "holy light source energy" of the Ellen Empire, etc., and what minerals are these super energy sources refined, This is the top secret of the state, and it will not be disclosed to the public at all.

However, if the flagship wants to jump to a star system within a certain star field, it must prepare an inducing force field in advance for positioning in that star system, for safety and secrecy, the general inducing force field is turned on by a frigate or cruiser with stealth ability before the flagship is ready to jump, but because the signal wave of the inducing force field is too strong, the enemy will immediately detect it and prepare for the battle in advance, but when the inducing force field is opened, there are generally a large number of conventional starship troops to defend to ensure the safety of the starship that releases the inducing force field, Therefore, it is difficult to obstruct, of course, the flagship can also make space jumps autonomously when the fuel is sufficient, but this kind of jump according to the judgment of the gravitational field of different stars can not accurately jump to the position in the star system that you want to reach, and it is often necessary to correct the orientation after the jump and carry out the second star system jump, this risk factor is relatively large, once the conventional combat starship can not go to escort in time, it is likely to be caught by the enemy in advance and destroyed by the group fire, so the loss can be much heavier, Because the cost of an ordinary small flagship is about ten times that of a conventional battleship, the dreadnought-class starship is 25 times that of a battleship, and the cost of a super flagship large star carrier is more than 200 times that of a battleship, not to mention the other side of the ultimate strategic starship, which is even more sky-high, and only powerful superpowers such as Huaguo and Ellen Empire have the ability to build it.
