The solution is to send a radar signal from the starting star to the target star, calculate the initial speed and the sub-light speed travel distance in the objective time compared to the speed of light and the distance traveled by the speed of light, and transmit such a radar signal in advance during the initial acceleration phase.

The radar signal will arrive at the target star five years ahead of Chu, and then feedback from the target star. When the first sub-light speed reaches the position where the side orbit is needed, it will receive this signal, and then unfold its own light sail. , Use Light Sail to change track.

Although the beginning of the sub-light speed does not know where it is, it still knows its own situation and its heading. As long as it knows this information, it uses itself as a reference to unfold the light sail and present a deflection angle. Atoms, photons, and other particles along the route will hit the light sail, causing the initial trajectory to be slowly deflected, just like a lone boat drifting on the ocean.

There is no need to do the rest. The route has been set long before departure. All problems will be solved by mathematics, and it can only be solved by mathematics. "I just hope that you don't encounter large substances above the molecular volume. That way, it is very dangerous."

After receiving the original orbit change signal, it unfolded the light sail to a predetermined angle as planned before departure. As for whether there was any orbit change, it did not know the halo of the star rainbow phenomenon. It will not change its position due to its angle deflection, as long as the sub-light speed does not decrease, it will always exist directly in front of its traveling direction.

Now that the signal is received, it means that it is already close to the target star system, which also means that it will face a lot of matter larger than the atomic volume and travel at the extreme speed of sub-light speed, even a grain of sand in space can give it. Early penetration injury. Not long after the light sail unfolded, at first we could see bright stars gradually detaching from the light cluster directly in front of it. First they were purple-blue, then gradually changed to blue-yellow, and then crimson...

The Doppler effect becomes very obvious at this time. Electromagnetic waves will be compressed when they are approaching, and stretched when they are far away, thus showing the color change between red and blue, which is caused by the constant speed of light. .

The impact of the scale reduction effect is a slow process when viewed from the outside world. It can be seen from the initial time perspective, but it is a very fast process. This scene change is somewhat similar to the spatial transition in science fiction works.

"There are so many stars, but there is still no way to be used as a reference for positioning."

Observing the changes in the outside world for the first time, it is waiting for the speed to drop further, and it can observe the cosmic stars, indicating that it has broken away from the sub-light state, but these stars are flying across its sides and thrown behind it. It shows that the speed is still too fast, so it needs to continue to wait at the beginning, it is not in a hurry, it has a lot of time to wait.

Its speed has dropped further. The most obvious evidence is that the surrounding stars have returned to the correct position and are fixed, and no longer converge in front of them to form a cosmic rainbow due to the Doppler effect.

But this speed is still very fast. The specifics are not clear at first. It has no method of measuring speed. It can only roughly judge that it is above the speed of the third universe, because it can easily get rid of the gravitational force of the target star by changing the angle of the light sail. Into the vast stars.

"It should be almost there now."

After the speed is lowered, it can no longer continue to spend time like this at the beginning. The material reserves are not enough. It needs to enter the star system as soon as possible, and then obtain the star light energy to maintain its own life activities, without the blessing of the scale reduction effect. Space voyage is a very time-consuming process, and you might be starved to death at first.

At this time, the position is outside the Kuiper belt. It can be determined that the stellar illumination is equivalent to the starlight, which is not enough to provide it with enough energy. It needs to approach the star.

"I have to be careful, otherwise it will be dangerous."

This reminded myself that I slowly deflected the light sail that extended from the tail.

The area of ​​Lightsail is very large, which increases the probability of being hit. It is not a problem that can be solved with first care. Its self-remind is meaningless and can only be regarded as a psychological comfort.

Although Chu had already lost the help from the group of the starting star after slowing down, and could not determine the location of the target star he was going to through the sky where he could not even find his starting star, it still has The method can determine the position of the star.

The method is always invented. After all, the target star is much closer than other stars, so the emission direction of those charged hydrogen atoms can be detected to determine the direction of the target star.

In fact, to put it plainly is the solar wind, as long as you go in the direction of the solar wind, you are absolutely right!

The first threshold is the Kuiper belt. Every star has its own Kuiper belt, which is destined to form. The formation of stars will inevitably be accompanied by residues~lightnovelpub.net~ and these remaining residues The Kuiper belt will inevitably form even if it is rarest to form planets. The only difference is the density of meteorite groups. If they are dense enough, planets or dwarf planets may be formed.

If you cross the Kuiper belt made up of meteorites without danger, you can judge the position of these meteorites through the occlusion of the starlight, and avoid them early. .

The Kuiper Belt is the second, but also the last, ghost gate that it faces at the beginning. Once it enters the star system and keeps a proper distance from the stars, it can maintain its own life activities and put a perfect end to this cross-stellar voyage.

Now that it has crossed the Kuiper belt, the rest is close to the star. After the target star can be observed remotely for the first time, the angle of the light sail is changed to move in the direction of the star's rotation. This way, the gravitational slingshot can be used to increase its speed and reduce the speed of the journey. Consumption, the cells of the whole body enter a semi-dormant state on purpose.

In this process, the trajectory of the initial use of gravity is the same as that of a small boat falling into a vortex, slowly approaching around a center.

During the journey, because of the proper angle, Chu once again received the ethnic information from the starting star. The signal was very weak, but it was still interpretable. "This is the ethnic group. At first, the will was right. Time defeated the empire. The empire's behavior to contain the development of the two colonial stars finally encountered the complete hostility of the Serines on the two planets. To our surprise, They look at the compatriots on Celine, and they look at the other races, which is really interesting."

"According to the plan, they will soon begin to launch independence in the next ten years. Time is really a terrible thing."
