"This is the beginning, all vital signs are normal, and there is no damage to the body, it is over."

　　 After completing the one-second regular report, I was distracted to pay attention to the external electromagnetic wave signal and its own situation information at first. At this time, it had already left the original star system.

The definition of sub-light speed is 90% or more of the speed of light. If the Kuiper belt is used as the boundary of the star system and the external subjective time, it only takes five minutes to leave the star system as the starting point and enter the star. The open area between.

　　 Lost the acceleration force of the sub-light orbit, the state of the initial body returned to the normal level. According to the description of the theory of relativity, the two objects move in the same direction and the same speed, and each other is a reference to each other, and they also maintain a relatively static state with each other.

At this moment, the initial acceleration to sub-light speed can also be understood as that each of the initial body accelerates to sub-light speed, so the particles maintain a relatively static state, so the body state returns to normal without tearing or tearing. There is a superposition of forces.

　　 In the end, it was still at sub-light speed relative to the outside world. Therefore, even a piece of tofu in front of it's course of travel was enough to kill it instantly.

Observing the outside situation for the first time, the surrounding area is pitch black. There is only one light source in front. This light source is rainbow-colored, with infrared rays below visible light in the center, and then gradually increasing the frequency. After visible light, you will see a crimson red. The ring is like a target for shooting. The outer circle is orange, and then yellow, green, cyan, blue, purple...

　　 Then, outside the purple, it breaks out of the category of visible light, which is the ring of ultraviolet rays.

　　The star rainbow phenomenon, the cosmic rainbow formed by the aberration phenomenon of relativity and the Doppler effect, is a wonderful scenery that can only be seen after entering such an extreme speed.

Light is light in any state, and it will not change due to the difference in the frame of reference. Even if the speed of light slows down due to different media, it is only the slowdown caused by the length of the path of light, not because the speed of light really drops. .

　　 "Is this what the will tells me to observe?"

　　 "It's really different from the world under normal conditions. It's very strange, but... what can the collection of these data bring to the group? It feels useless."

　　 "No, it's useful, the will can't be wrong, but I'm too stupid to understand the intention of the will."

　　 "Huh? One second later, continue to broadcast radio information."

　　 First read the timing information of the atomic clock in his body, and repeat the broadcast of radio information.

　　 "This is the beginning, all vital signs are normal, and there is no damage to the body, it is over."

This is meaningless, because the distance is too far, and the electromagnetic wave will decrease with the distance. To solve this problem, you can only increase the energy output, but unfortunately, the energy carried by itself is not much. Don't say let Ming receive his report information.

The original intention of formulating this plan was just thinking that they wanted to use the first few feedbacks to measure the impact of the scale reduction effect after reaching the sub-light speed, so as to estimate the ratio of the initial time to the outside time. By the way Collect data for use when navigating at sub-light speeds for other races.

However, when the plan was finalized, they changed their minds. No matter how weak the light is, it will not disappear out of thin air, but it is too weak to be captured by the existing radar technology. This does not mean that the future radar technology will not work. What if during the period of time when they first went to the target star, thought they had a technological explosion in radar technology? Based on this hope, although it is a waste of energy, they still require radio information to be sent every second at the beginning.

　　 After reporting the information, it returned to a state of doing nothing at first, but this does not mean that it can relax its mood, but it has to withstand a small-scale bombing every once in a while.

　　 For mothership creatures, cosmic navigation is very quiet, but at first it was just the opposite. From the beginning, it was shrouded in ‘noisy’, so that it missed the quiet universe at normal speed.

The space between the star and the star is very thin and empty, but it does not mean that there is no matter. On average, there is a hydrogen atom for every cubic meter, which is a large scale of five light-years between the starting star and the target star. At least initially it will hit 9x1015 hydrogen atoms head-on.

Everything is relative. The effect of relativity is very obvious in large-scale cosmic space. The initial impact of hydrogen atoms on the route at sub-light speed is equivalent to that of the hydrogen atoms on the route crashing head-on to standstill at sub-light speed. In the beginning, the energy released is equivalent to a grenade. In other words, every short interval in the beginning, you have to take a grenade bombing with your face. Such bombing will have to withstand at least 9x1015 times.

The impact of these hydrogen atoms is impossible to avoid. They have already dispersed between the stars. The electricity carried by the stars at the beginning is generally neutral. It is impossible to deflect by the electric field and can only be resisted. .

Fortunately, the collectors had anticipated this situation long before they set off~lightnovelpub.net~ so they used a high-density titanium alloy exoskeleton as the initial shell. The initial life structure, not to mention the grenade explosion, as long as Not at the center of the nuclear explosion, hardly resisting a nuclear explosion with the equivalent of 10 million tons is completely fine.

　　 If it hadn't reached such an intensity, the collectors would not have the confidence to sail across the star at subluminal speed.

Time just passed by under the repeated repetition of Chu. Chu didn’t even notice that time was passing. There was nothing to do. The surrounding environment was empty. Only the cosmic rainbow in front was always shining in front, as if it was immutable. , It is easy for people to have such an illusion-the world is like this, and he is not in motion at all, just staying relatively static with the light source in front.

　　 Fortunately, the hydrogen atoms that collide from time to time and the atomic clock in the body will dispel this initial illusion, reminding it all the time that this world is not like this.

Time passed slowly, and the initial mood became more and more tense. The hydrogen atoms on the route can only be regarded as small gaps. If you successfully cross the long distance between the star and the star without encountering any large masses Entity, then it means that I passed the first ghost gate and arrived at the second.

　　 This second ghost gate is to complete the sub-light speed of deceleration and enter the star system.

　　 sounds easy, but in fact...too difficult.

　　The sub-light speed at the beginning relied on the acceleration of the outside world, not on itself. The increase in speed was easy and safe, but it did not have the ability to slow down.

　　 The only thing it can rely on is the solar sail.
