Chapter 420: Chapter 421 Sub-light Journey (Part 2)

"This is the beginning. At present, all the vital signs are normal, and there is no damage to the body. That\'s over."

After the routine report at an interval of one second, it was distracted to pay attention to the external electromagnetic wave signal and its own situation information. At this time, it had already left the original star system.

The definition of sub-light speed is ninety or more than ninety percent of the speed of light. If the Kuiper belt is used as the edge boundary of the star system and the subjective time of the outside world, it only took five minutes to leave the star system as the starting point and enter the open zone between the stars.

Without the acceleration force of the sub-light orbit, the state in the body returned to a normal level. According to the description of relativity, the two objects move in the same direction at the same speed, refer to each other, and also maintain a relatively static state.

At this moment, the initial acceleration to the sublight speed can also be understood that each of the initial body accelerates to the sublight speed, so the particles remain relatively static, so the body state returns to normal, and there is neither tearing nor the superposition of forces.

But in the final analysis, compared with the outside world, it is still in a state of sublight speed. Therefore, even a piece of tofu in front of its route is enough to make it die in an instant.

At the beginning, when observing the situation outside, it was dark around, and only the only light source existed in front of it. This light source is presented as a rainbow color. The center is the infrared below the visible light, and then the frequency increases step by step. After the visible light, you will see a red ring, like a shooting target, and the outer ring is orange, but Then there are yellow, green, blue, blue, purple...

Then it is out of the scope of visible light outside the purple, which is the ring of ultraviolet light.

The star rainbow phenomenon, the cosmic rainbow formed by the photo 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. It will not change because of different reference frames. Even if the speed of light slows down caused by different media, it is only the slowdown caused by the path length of light, not the real decline in the speed of light.

"Is this what the will makes me observe?"

"It\'s really different from the world in a normal state. It\'s very wonderful, but... What can collecting this data bring to the ethnic group? It feels useless."

"No, it\'s useful. The will can\'t be wrong. It\'s just that I\'m too stupid to understand the intention of the will."

"Huh? After a second, continue to broadcast radio messages.

Read the timing information of the atomic clock in your body for the first time, and repeat the broadcast of radio information.

"This is the beginning. At present, all the vital signs are normal, and there is no damage to the body. That\'s over."

It is meaningless to do so, because the distance is too far, and the electromagnetic waves will decrease with the distance. If you want to solve such a problem, you can only increase the output of energy, but it is a pity that you don\'t carry much energy at the beginning, let alone let it receive your own reporting information.

The original intention of formulating this plan was to determine the impact of the initial shrinkage effect after reaching the sub-light speed through the initial feedback information, so as to estimate the ratio of the initial time to the external time, and collect data for other races to use it for sub-light speed navigation.

However, when the plan was finalized, they changed their mind. 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, which does not mean that the future radar technology is not good. If they first went to the target star, they will have a radar technology. What about the technical explosion? Based on this hope, Although it is a waste of energy, they still require them to send radio information every second.

After reporting the information, it returned to a state of doing nothing at the beginning, but this does not mean that it can relax. It has to withstand a small-scale bombing every time.

For mothership creatures, space navigation is very quiet, but at the beginning it is exactly the opposite. From the beginning, it is shrouded in \'noisy\', so that it misses the quiet universe at a normal speed.

The very thin and empty space between stars does not mean that no matter exists. On average, there will be a hydrogen atom per cubic meter. The large scale of five light years between the star and the target star will hit at least 9x1015 hydrogen atoms head-on at the beginning.

Everything is relative. The relativistic effect is very obvious in large-scale cosmic space. At the beginning, it hits the hydrogen atom on the route at sublight speed, which is also equivalent to the hydrogen atom on the route hitting the stationary head at the speed of sublight. The energy released is equivalent to a grenade. In other words, the initial interval For a short time, you have to use your face to receive a grenade bomb, which will withstand at least 9x1015 times.

The impact of these hydrogen atoms is unavoidable. Wandering between the stars, they have long dissipated the electrical properties they carried from the stars. They are generally neutral. It is impossible to deflected through the electric field and can only resist hard.

Fortunately, the collectors expected this situation early before sailing. used the high-density titanium alloy exoskeleton as the initial shell. Not to mention the initial life structure, as long as it is not in the center of the nuclear explosion, it will be resistant to tens of millions of tons. The amount of nuclear explosion is completely no problem.

If it hadn\'t reached such a strength, the collectors would not have the confidence to sail at sublight speeds across stars.

Time gradually passes under such repetition at the beginning. At the beginning, I can\'t even notice that time is passing. There is nothing I can do. The surrounding environment is empty. Only the cosmic rainbow in front of me has been shining in front of me. As if it is eternal, it is easy to make people have such an illusion - the world is like this, and I don\'t have it at all. It is in motion, but it is relatively static with the light source in front of it.

Fortunately, the hydrogen atoms that hit from time to time and the atomic clocks in the body will dispel this illusion at the beginning and remind it that this is not the case in the world.

Time passes slowly, and the initial mood is gradually becoming tense. The hydrogen atoms on the route can only be regarded as small gullies. If you successfully cross the long distance between stars and stars without encounter any mass entities, it means that you have first passed the first ghost gate and reached the second one. .

This second ghost gate is to complete the decelerated navigation at sublight speed and enter the stellar system.

It sounds easy, but in fact... it\'s too difficult.

The initial sub-light speed relies on external acceleration, not itself. The speed increase is easy and safe, but it does not have the ability to slow down.

It can only rely on the sun sail.
