Chapter 423: Beyond the Race (Part II)

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

The radar signal will travel five years in front of the initial to reach the target star, and then feedback back from the target star, and when the sub-light speed of the initial travel reaches the position where the side rail is needed, it will just receive this signal, and then deploy its own light sail and use the light sail to change orbit.

Although the sub-light speed does not know what position it is in, it still knows its own situation and its own course, as long as it knows this information, it uses itself as a reference to unfold the light sail to present a deflection angle, atoms, photons and other particles along the route will hit the light sail, so that the initial trajectory slowly deflects, like a lonely boat drifting on the ocean.

There is nothing left to do at the beginning, the route has been set before departure, and all problems are left to mathematics to solve, and it can only be left to mathematics to solve, leaving it to fate.

"I just want not to encounter large substances that are larger than the volume of molecules, which would be very dangerous."

After receiving the orbit change signal that was originally transmitted, it initially unfolded the sail to a predetermined angle according to the plan before departure, and as for whether there was an orbit change, it did not know that the halo of the star rainbow phenomenon would not change its position because of its angle deflection, as long as the sub-light speed did not decrease, it would always exist directly in front of its travel direction.

Since 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 size of an atom, traveling at extreme speeds such as sub-light speed, even a grain of sand in space can give primal penetrating damage.

Not long after the sail was unfurled, the bright stars could be seen gradually detaching from the light clusters directly in front of it, first purple-blue, then blue, then red......

The Doppler effect becomes very pronounced at this time, as electromagnetic waves are compressed when approaching and stretched away from them, resulting in a color shift between red and blue, which is the result of the constant speed of light.

The effect of the shrinkage effect, the slowdown is a slow process when observed from the outside world, but it is a very fast process from the perspective of time at the beginning, and this kind of scene change is somewhat similar to the spatial leap in science fiction works.

"There are a lot of stars, but there is still no way to use them as a reference for positioning."

At first glance, it was waiting for its speed to decrease further, and it could observe cosmic stars, indicating that it had broken away from its sub-light state, but these stars were rapidly passing over its sides and throwing them behind it.

It shows that this 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.

The most obvious evidence of the further decrease in its speed is that the surrounding stars have returned to their correct positions and are fixed, and no longer converge directly in front of them to form a cosmic rainbow due to the Doppler effect.

But this speed is still very fast, the specific is not clear at first, it has no way to measure the speed, can only roughly judge that it is above the third cosmic velocity, because as long as it changes the angle of the light sail, it can easily get rid of the gravitational pull of the target star and escape into the vast stars.

"It should be about the same by now."

After the speed is slowed down, the beginning can no longer continue to squander time like this, the material reserve is not enough, it needs to enter the star system as soon as possible, and then get the stellar light energy to maintain its own life activities, without the blessing of the shrinkage effect, the space voyage is a very time-consuming process, and it will starve to death if it is not done at first.

At this point, the position at the beginning of the year was outside the Kuiper Belt, which can be determined that stellar illumination is equivalent to starlight, and it is simply not enough to provide it with enough energy, it needs to approach the direction of the star.

"I need to be careful, or it'll be dangerous."

This reminds me that I am slowly deflecting the light sail that extends from the tail.

The large area of the light sail increases the probability of being hit, which is not a problem that can be solved with initial care, and its self-reminder is meaningless, which can only be regarded as a psychological comfort.

Although Chu had lost the help of the group from the starting star after slowing down, and was unable to determine the location of the target star it was going to through the stars in the sky where it couldn't even find its own starting star, it still had a way to determine the position of the star.

The method is always come up with the fact that the target star is much closer than the other stars, so it is possible to detect the direction of emission of those charged hydrogen atoms and thus determine the direction of the target star.

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

The first threshold is the Kuiper belt, each star has its own Kuiper belt, which is destined to form, the formation of stars will inevitably be accompanied by the remainder of the debris, and these remaining residues will inevitably form the Kuiper belt even if they are the rarest and do not form planets, the difference is only in the density of the meteorite group, if it is dense enough, it may form planets, or dwarf planets.

There is no danger of crossing the Kuiper belt composed of meteorites, and at the beginning through the obscuration of the starlight, so as to judge the location of these meteorites, and avoid them in advance, otherwise wait until they enter the horizon range, with the efficiency of the light sail, the consequences can be imagined.

The Kuiper Belt is the second and last of the first to enter the stellar system and keep a proper distance from the star, so that it can maintain its own life activities and draw a perfect end to this transstellar voyage.

Now that the Kuiper Belt has been crossed, all that remains is to approach the star, and after being able to observe the target star remotely, change the angle of the light sail and move in the direction of the star's rotation, so that you can use the gravitational slingshot to increase your speed, and at the same time, in order to reduce the cost of the journey, you will intentionally let the cells of the whole body enter a semi-dormant state.

In this process, the trajectory of the initial gravitational force is the same as that of a boat falling into a vortex, slowly approaching a center.

During the journey, because of the appropriate angle, Chu once again received the population information from the starting star, and the signal was very weak, but it could still be interpreted.

"This is the race, at the beginning, the will is right, time defeated the empire, the empire curbed the development of the two colonial stars, and finally met with the complete hostility of the people of the two planets, to our surprise, they actually looked at the people on the Seren in the same way as the alien race, it is really a very interesting thing."

"According to the plan, they will soon start to launch independence in the next ten years, and time is a terrible thing."
