There are only three dwarf planet spaceships, which can accommodate not many robots, accounting for only about 5% of the total, and the rest are distributed to work on thousands of asteroid spaceships and material objects.

The Kuiper Belt consists of ice-covered rocks and dwarf planets orbiting around the Kuiper Belt over the centuries, and now about 1,500 Kuiper Belt objects ranging in diameter from thousands of meters to thousands of kilometers have been discovered, and more than 1,000 of them are being subjected to crude resource gathering operations.

The most tricky thing about the Kuiper Belt is the ultra-low temperature environment of about minus 260 degrees Celsius, and in the face of such a harsh environment, it is very difficult to directly board the celestial bodies and mine them, so Tan Qiusheng deployed thousands of asteroid spacecraft to the Kuiper Belt, and directly blasted those large celestial bodies, and after blowing them up, they can use gravity to capture matter, which is very efficient and extremely low-cost.

In the orbital radius of 30,000 to 100,000 astronomical units, there are hundreds of billions of comets, these comets are also the target of collection, because the comet is relatively fast, and too far away, so the difficulty of mining will be much higher than that of frozen rocks and dwarf planets, so at present, only some comets close to the star are selected for testing, and not much manpower and material resources have been invested, so the harvest is not very much, these will wait until more than 1,500 Kuiper Belt objects are collected, and large-scale capture of comet material will be considered.

After unloading, the materials such as stones, dirt and other materials that cannot be used temporarily in the warehouse of the dwarf planet spacecraft will be packed in boxes similar to containers, which themselves are non-powered sealed vehicles, these containers are huge rectangles of standard models, and can be locked together with each other, gathered into a more colossal object, and then these are linked together. And let the spacecraft drag them to different orbits of the star, let them orbit the star by inertia, and then pick them up when they are needed later.

The Kuiper Belt is 7 billion kilometers away from the star system, and most areas in this range can be used to park these materials, because the space is too large, so Tan Qiusheng is afraid that he will not be able to find them, in order to prevent the loss of materials, these containers parked in star orbits will place some signal equipment to locate their positions, and another function is to inform their specific locations in time, so that the spacecraft can know the situation ahead in advance, and can avoid space collisions.

After hundreds of years of development in spacecraft, the curvature engine has been developed and applied, so a distance of 7 billion kilometers can be completed in a single transportation mission for a small number of spacecraft today.

The curvature engine is an application of space, nuclear fission and nuclear fusion can cause changes in space, nuclear fission will make the space in the universe shrink into the microscopic world, this process will form a state of collapse of space, and nuclear fusion is the release of space in the microscopic world, and the microscopic space will spread sharply in the universe, and this process will form a state of space expansion.

Both collapse and expansion can have an impact on the universe, so we can design targeted engines for them respectively, and the engines made by using the principle of space collapse rely on the space suction formed when the space collapses. The engine made by using the principle of space expansion relies on the space thrust formed when space expands.

The two engines are compatible, as long as they are installed on the front and rear sides of the spacecraft, as long as the two ends of the spacecraft can reach sub-light speed, then theoretically, the cumulative acceleration of 1+1 will reach the speed of light or far exceed the speed of light.

The distance of teleportation depends on the range and distance of the warp space, the range represents whether the object can pass through normally, and the distance is how far it can be teleported, if it is really teleported according to the distance of the spaceship's own warp space, then it will not be able to teleport far.

So on this basis, it is also necessary to build a teleportation array at the destination, these teleportation arrays are built in the space environment, and they are extremely huge, and the largest teleportation array currently built can only teleport asteroid spaceships.

Each teleportation array needs to set the spatial frequency, and basically the spatial frequency of these teleportation arrays is fixed, so that other spaceships can use them to carry out accurate position teleportation.

The teleportation array is always active, and if this section is turned off, other spaceships will not be able to find it and use it to teleport.

The teleportation process of the spaceship is to use the collapsed space to focus on a space vortex, and the center of the space vortex is a point, and this point must be at the same frequency as the point of the space vortex of the corresponding teleportation array, so that these two points can resonate.

Under the impetus of space expansion and the action of space suction, the spaceship can enter the space vortex (the space vortex needs to cover the area of the entire spaceship, its space expansion is the thrust, and it is also the expansion recovery force after the teleportation, the time for teleportation preparation will be very long, and the teleportation process is only a momentary thing, just like penetrating a wall of air, you can directly step on the opposite side. ）

In the process of entering, the spaceship seems to be distorted by space, and continues to shrink, and then slowly becomes a point, and finally teleports to the point of the teleportation array.

Through the spaceship of the teleportation array, the people and objects on it are intact, this is because space is not matter, what we see is only the appearance, we can compare the point of this space vortex to a miniature world, just like the nature of the miniature world in the atom.

As mentioned earlier, as long as a small part of the spaceship has a curvature engine, and most of them fail to use it, it is very simple, because Tan Qiusheng does not have so many resources to build such an expensive spaceship, and there is no need to do so.

To achieve teleportation, as long as the teleportation array is built in the place where it is needed, adjust the frequency of the teleportation array, and reach the teleportation array at the other end, as long as there are two teleportation arrays in each place, one with a fixed frequency to receive the outside world, and one for the special teleportation spaceship, then it's fine.

This utilization rate is the highest, and it is more energy-saving, and the curvature spacecraft also has a lot of roles, because they can use space, they are very fast in speed, fast means that they are very versatile, you can send them to explore other distant places, build more teleportation arrays, and send more curvature spaceships to explore in the direction of the earth, to see if they can find the earth, and in the space close to the earth, build a teleportation array and so on.
